Tower cranes have been used more and more in construction sites and have produced good economic and social benefits. However, due to the continuous renewal of the engineering structure and the ever-increasing building height, tower cranes have been used more and more widely in urban and rural areas. Due to their great harm and inefficiency, tower cranes have gradually become a social focus in the construction safety production process. BQ TOPLESS TOWER CRANE The frequent occurrence of tower...

Luffing jib tower crane and level jib tower crane are two kinds of common models. Both models are widely used but they differ in their structure, operating principle, and application field. Luffing jib tower crane is mainly used in large projects and industrial equipment installing fields where large lifting capacity, high perching accuracy, and high safety are required for lifting large members and equipment components. The level jib tower crane is mainly used in the common civil building...
The Derrick Crane Roof Crane is installed in a fixed place. The mast and a jib are fasted to a slewing platform. The mechanism and electrical parts are also placed on the platform. The height of the working platform can be adjusted within 1150-1800mm with arm which can be stretched out and drawn back. It can be widely used on parapet and complicated building in different height. The derrick crane is a large hoisting mechine similar to tower crane in most respects, except for its stationary...
A luffing-jib crane is characterized by the ability to raise and lower its jib, which allows it to reduce the turning radius. The luffing crane is also a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius is highly reduced in comparison to standard tower crane types. The luffing tower crane also has a higher lifting capacity because the weight is transferred from the crane’s jib much more effectively. BQ's 12ton luffing tower...

When the jacking of a tower crane is too slow, the following problems may exist: 1) Oil Hydraulic Pump Station wear, efficiency decline; 3) Valve stem and valve hole of manual directional valve are seriously worn; 4) Tower Crane Cylinder piston seal damage, internal leakage. Recommended solution: 1) Repair or replace damaged parts; 2) Add sufficient oil; 3) Clean the oil filter.
Suspended platform, as temporary suspended cradle platform, are widely applied in maintenance applications such as curtain fecade cleaning in high rise building, painting, glazing repairs, bill- board painting, cable installation and other outer working of high rise building up to 150 meters about 30 floors high. Our ZLP series Suspended Cradle Platform, ZLP1000, ZLP800, ZLP630, ZLP500, ZLP400 and ZLP150, are good choices for fulfill above outside of wall work.
A construction hoist is a lifting system often used at construction sites to lift personnel and materials to upper levels of unfinished buildings. The passenger hoist consists of a cage (or two) in which people will stand during transport, and a track that is mounted to the building. The cage will travel along this track by means of a rack and pinion drive system, and the Passenger Hoist Cage can be stopped at various locations along the track. This allows people to load or unload at any floor...
The Derrick Crane Roof Crane is installed in a fixed place. The mast and a jib are fasted to a slewing platform. The mechanism and electrical parts are also placed on the platform. In addition to general used suspending mechanism, we can also make special suspending- platform in accordance with different building wall. The derrick crane is a large hoisting mechine similar to tower crane in most respects, except for its stationary foundation. BQ models of derrick crane includes 10T Derrick Crane...

This is because the slewing radius is highly reduced in comparison to standard tower crane types. The luffing tower crane also has a higher lifting capacity because the weight is transferred from the crane’s jib much more effectively. BQ models of luffing tower crane ： GHD4015-6；GHD4510-6; GHD5012-8; GHD5020-10;GHD5030-10；GHD5522-12; GHD5027-14; GHD6032-18; GHD6091-32, ect.
Tower cranes are fixed to the ground on a concrete slab (and sometimes attached to the sides of structures), tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall buildings. The base is then attached to the mast section which gives the crane its height. 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. BQ...
Topkit Tower Crane also called hammer head tower crane is the tower crane with tower head and horizontal jib (jib and counter jib). The tower head is the fulcrum of tie-bars chains connected to jib and counter jib.The jib carries the load, with a trolley that runs along its length to move the load in and out. The counter jib holds the hoisting motor. It also contains electronic controls, the cable drum, and concrete counterweights to keep balance. BQ GHT6015-10T tower crane is top-slewing with...
