Tower cranes are used because they are efficient at lifting and moving heavy materials while having a relatively small footprint on site. Tower cranes are great at lifting material and moving across long distances. Their reach allows them, in a lot of locations to have unencumbered access to the entire job site. There are three types of BQ tower cranes, that is hammerhead tower crane, flat top tower crane and luffing tower crane. Each type has different models.

1. Luffing Tower Crane Luffing tower crane is a type of tower crane which is widely used in cities and limited space. They have a very short counter jib and a variable working radius, which permit high productivity in extremely narrow spaces. 2. Topkit Tower Crane Topkit tower crane is tower cranes with tower head. The tower head is the fulcrum of tie-bars chains connected to jib and counter jib. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing invulnerability and lowers the weight of jib & counter jib (simple transforming beam in mechanical model). 3. Topless Tower Crane Flat top tower crane is easy for assembly. May Flat Top Cranes have been used on construction projects or near airports where overhead clearance is taken into a consideration.

The wire rope is wound around the hoisting drum and connected to the hook block. The steel rope is made of high-strength steel and have a high load-bearing capacity. Multiple steel wire rope are used to distribute the load evenly and ensure stability during lifting operations. Wire rope is an essential component of tower cranes as it provides the necessary strength and flexibility to lift heavy loads. Tower cranes typically use high-strength steel wire ropes that are specifically designed for heavy-duty lifting applications. The wire rope used in tower cranes is typically made up of multiple strands of steel wires twisted together to form a strong and durable rope. The number of strands and wires in the rope can vary depending on the specific requirements of the crane. Tower crane wire ropes are designed to withstand high loads and provide excellent resistance to abrasion, fatigue, and corrosion. They are also engineered to have a high breaking strength to ensure safety during lifting operations. Regular inspection and maintenance of the wire rope is crucial to ensure its safe and efficient operation. This includes checking for signs of wear, corrosion, or damage, as well as lubricating the rope to reduce friction and prolong its lifespan. Overall, wire rope is a critical component of tower cranes, providing the necessary strength and reliability to handle heavy lifting tasks in construction and other industries.

1. Plan and prepare: Before starting the tower crane erection process, thoroughly review the manufacturer's instructions and guidelines. Create a detailed plan that includes the necessary equipment, tools, and personnel required for the job. 2. Site preparation: Ensure that the site is properly prepared and leveled to support the tower crane. Clear any obstacles or debris that may hinder the erection process. Make sure the ground is stable and compacted. 3. Assemble the base: Begin by assembling the tower crane base. Follow the manufacturer's instructions to securely anchor the base to the ground. Use proper bracing and leveling techniques to ensure stability. 4. Erect the mast sections: Assemble and erect the mast sections of the tower crane one by one. Use a suitable lifting device, such as a mobile crane, to lift each section into place. Ensure proper alignment and connection of the mast section. 5. Install the jib and counterweights: Once the tower crane mast is erected, install the jib and counterweights according to the manufacturer's instructions. Ensure that all connections are secure and properly tightened. 6. Electrical and hydraulic connections: Connect the electrical and hydraulic systems of the tower crane. Follow the manufacturer's guidelines to ensure proper wiring and connection of all components. 7. Test and inspect: Before putting the tower crane into operation, conduct a thorough inspection to ensure that all components are properly installed and functioning correctly. Test all controls, brakes, and safety features to ensure they are in working order. 8. Training and certification: Ensure that all personnel involved in operating the tower crane are properly trained and certified. Provide necessary training on safe operation, emergency procedures, and maintenance requirements. 9. Regular maintenance: Develop a maintenance schedule for the tower cranes and follow it diligently. Regularly inspect and lubricate all moving parts, check for wear and tear, and address any issues promptly. 10. Safety precautions: Prioritize safety throughout the entire erection process. Follow all relevant safety regulations and guidelines. Use appropriate personal protective equipment (PPE) and implement proper safety procedures to minimize the risk of accidents or injuries.

Tower Crane anti-collision system is a safety feature designed to prevent collisions between tower cranes. It uses sensors and technology to detect potential hazards and alerts the driver or takes action to avoid a collision. One complete set of anti-collision system including a disply of Load Moment Limiter, a signal access module, a mainframe, a wind speed sensor, weight/amplitude limiter, a slewing sensor,ect. Anti-collision systems are commonly found in tower cranes, automobiles, aircraft, and ships. They can include features such as automatic emergency braking, lane departure warning, blind spot detection, and adaptive cruise control. These systems have been shown to significantly reduce the number of accidents and fatalities on the road. Remember, the specific requirements for an anti-fall safety device may vary depending on local regulations and the type of building hoist being used. It is essential to consult with safety experts and follow applicable safety standards and guidelines.

Luffing Tower cranes are especially demanded tall buildings on congested sites. They have a very short counter jib and a variable working radius, which permit high productivity in extremely narrow spaces. It's common to have limited space and clearance when working with a tower crane in an urban metro area and downtown work sites. A luffing tower crane is ideal for building projects where there's not much space on either side of the site and you need to work safely. A luffing crane is able to raise or lower its jib, and that allows it to reduce the slewing radius. But there are some disadvantages of the luffing cranes when you compare them to a tower crane: The price of the luffing-jib crane is much higher than a regular tower crane. The tower frames of a luffing tower crane are stronger, and the luffing mechanisms are much bigger than the hoist system of a tower crane. Of course, the technology applied to move the jib, counterweights, etc is the highest. The cost of assembling and disassembling are much higher too. Most of the structures are heavier, and it takes longer to erect a luffing-jib crane. Once again, to erect a crane is more difficult due to the technology applied, etc. The jib of a luffing crane acts as a wall to the wind, and the load moment is much bigger. So the restrictions of the tower are higher. Due to the luffing cranes don't have trolley motor (the movement is made by the total jib), the working process is slower than in a tower crane.

A flat top tower crane is a type of tower crane that has a flat top instead of a traditional A-frame design. This allows for easier assembly and disassembly of the crane, as well as increased flexibility in terms of the crane's reach and lifting capacity. Flat top tower cranes are commonly used in construction projects where space is limited or where the crane needs to be moved frequently. They are also popular in urban areas where there are height restrictions or where the crane needs to be positioned close to other buildings.

1. Luffing Tower Crane Luffing tower cranes are a type of tower crane commonly used in construction projects. Unlike traditional tower cranes, luffing tower cranes have a jib that can be raised or lowered to adjust the height and reach of the crane. This allows them to work in tight spaces or in areas with height restrictions. Overall, luffing tower cranes are a valuable asset in the construction industry, providing flexibility, efficiency, and safety in various construction projects. 2. Topkit Tower Crane Topkit tower crane is tower cranes with tower head. The tower head is the fulcrum of tie-bars chains connected to jib and counter jib. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing invulnerability and lowers the weight of jib & counter jib (simple transforming beam in mechanical model). 3. Flat Top Tower Crane A flat top tower crane is a type of tower crane that has a flat top instead of a traditional saddle jib. This design allows for easier assembly and disassembly of the crane, as well as increased flexibility in the placement of the crane on a construction site. Flat top tower cranes typically have a maximum lifting capacity of up to 20 metric tons and can reach heights of up to 80 meters. They are commonly used in high-rise building construction, as well as in infrastructure projects such as bridge construction and power plant construction.

Luffing Tower Crane Topkit Tower Crane Luffing tower cranes have a jib that can be raised and lowered vertically, allowing them to work in confined spaces or areas with height restrictions. This makes them ideal for urban construction sites where space is limited. They also have a higher lifting capacity than topkit tower cranes. Luffing tower cranes are especially useful in urban environments where space is limited. The ability to adjust the jib angle allows the crane to work around obstacles such as buildings or other structures. Topkit tower cranes are a type of tower crane that feature a top-mounted counterweight system. The counterweight is positioned on the top of the tower and helps to stabilize the crane during lifting operations. This design allows for increased lifting capacities and higher hook heights compared to other types of tower cranes. Both types of tower cranes have their advantages and disadvantages, and the choice between them will depend on the specific needs of the construction project.

Electric motors are the crucial parts of a tower crane, there are three types of motors for tower crane: Tower Crane Hoist Motor, Tower Crane Trolleying Motor and Tower Crane Slewing Motor. How to maintenance and repair them? 1.Keep tower crane motors are free from dirt, fiber, miscellaneous subjects, water and other conductive liquid; especially on these parts: carbon brush, slip ring and inlet&outlet of ventilation, make sure that they all have good performance. 2. In order to ensure the motors are well lubricated during operation, grease should be applied or replaced every 5000 hrs. First, pay attention to replace the overheated and deteriorated grease in time. Next, remove away the previous grease , clean the shaft and bearing with gasoline. Finally ,follow the instruction to fill the grease into the cavity between inner and outer bearing rings, to degree if it fills 2/3 of the cavity. 3.In case that motor protective device acts continuously, attention should be paid to confirm if the motors are overloaded running or set low in value. In addition,Check the motor casing and make sure the packing insulation value is over 0.5M.The cable of motor shall be free from damage.Tighten the bolt of motor if have demand.

When installing the building hoists, what safety measures is required? 1. Clean the erection site and fence it with railings. No admittance except on business, forbid constructing operation above the construction hoist when installing to prevent anything fall down to the erection site. 2. There must be the person who has specific duty for installation. 3. Strictly forbid operating the building hoist by non-working person during installing. 4. Operating hoist must be at the roof of cage, don't operate it in Passenger Hoist Cage. 5. The installation can not be done when snow, storm and the wind speed exceeding 13m/s. 6. The lifting device is only use for installing and dismounting parts of hoist and can not be permitted overload. 7. Don't stand under the lifting device during the device is working. 8. Don't move the cage when something is on the lifting device. 9. Person's head and hand can not be out of the safety railing when the hoist is operating. 10. Forbid starting the hoist when someone is working at mast or tie-in; None be allowed to go into the enclosure when the cage goes up. 11. Inspect every parts before the hoist is started. 12. During installation, the load of hoist must be less than the rated load. 13. Do not forget tighten connecting bolts of Construction Hoist Mast Section and tie-in. 14. Inspect and adjust verticality of mast when installing tie-in. 15. After installation, lubricate according to manual.

How to prevent mechanical wear of wire rope? 1.The mechanical wear of steel wire rope is caused by the running of machine material. In the using process of tower crane, the outer surface get in touch with the surface of the wheel groove, the drum, etc., causing wear, and the wire diameter will be thinned after the wear, and the outer steel surface of the wire is worn and smoothed. Wire surface wear contains single-sided wear and overall wear. 2.The bending fatigue fracture of the tower crane wire rope is caused by rope passing through the wheel groove and retracting of rope in the drum. The steel rope first forms an initial crack due to various slips, and then the crack tip repeatedly deforms under the action of shear stress, causing the crack to expand and fracture. 3.Prevention and improvement measures: Firstly, we need to increase the number of the outer wires of the wire rope and reduce the diameter of the outer wire. Secondly, reduce the wire line tension, increase the wheel groove and the drum diameter to increase the durability of the wire rope. Thirdly, lubricate the wire rope, and also apply grease, reduce the friction between the steel wire rope and the equipment to improve the fatigue resistance of the wire rope.

Jacking is an important work in the use of tower crane, and is also an accident-prone stage. Only by making full preparations and take the announcements during and after the completion of the construction, can we ensure the smooth progress of the work. There are some special notice for tower crane jacking: 1. Preparatory work before jacking of tower crane Prepare the mast sections to be added according to the required raising height of the tower, and line masts up along the jib. The on-site staffs in charge of jacking in their place according to the duties. Check whether the hydraulic system works normally, ensure that the pressure of hydraulic oil is in line with the regulations, the expansion of the piston rod is stable without jam phenomenon. Check the condition of jacking beam and hanging plate. Adjust the clearance between jacking guide wheel and tower main chord to meet the requirements. According to the manual, lift one mast section to be added to the imported beam, and then lift another mast section, move the luffing trolley to find balance and lock the slewing mechanism. 2. Matters needing attention during jacking During jacking, special personnel should be in charge of the command, special personnel in charge of taking care of the power supply, special personnel in charge of operating the hydraulic pump, special personnel in charge of supporting the jacking beam, special personnel in charge of pulling climbing claw, special personnel in charge of installation of the mast section. All personnel must concentrate, follow instructions and stick to their posts. Jacking work is not allowed at night. In special cases when jacking must be carried out, adequate lighting must be provided. Jacking work is strictly prohibited when the wind speed exceeds level 4 or the speed specified in the manual. During the jacking process, in case of sudden wind, jacking work should be immediately stopped. During jacking, do not rotate the jib and operate the trolley. Jacking work must be stopped immediately for inspection in case of jam or other fault. If the fault is not eliminated, jacking shall not be continued. The operator must concentrate on the operation, do not put his head into the scope of imported guide wheel, so as to avoid injury from sudden movement of the mast section. Pay attention to check the required releasing length of cable, and strictly prevent cable from being pulled, jammed and squeezed in the process of moving. The newly introduced mast section must be firmly connected with the upper and lower tower before the next continued jacking operation 3. Matters needing attention after jacking Check and tighten the height bolts connecting upper and down towers. Check whether the operating handle of the hydraulic system has been set to zero position. Check and put off the power of hydraulic jacking system. Remove the mast section used for balance on sling steel , and start the locking condition of slewing mechanism.
