Fig of tower crane QTZ63(5013)
tower crane Specifications:
QTZ63(5013) is a new type of self-raising tower crane.It has 3 jib radius, Max. radiu 55m, Max. hoisting load 6t, key features as following:
- Stationary height 41m
- Attached height 160m to 200m
- Max load moment 870kNm.
- Standard jib radius is 50m,there are 50m,45m and 55m three jib radius which can meet different site require.
- when jib radius 50m,Max load 6t at 13.72m, jib end load1.3t
- when jib radius 45m,Max load 6t at 14.48m, jib end load1.6t
- when jib radius 55m,Max load 6t at 12.13m, jib end load1.0m
Description of tower crane works:
- The hydraulic climbing is used on the upper to add or reduce tower mast section, which make the hoisting height of the tower crane can vary with the height of the building.High working speed, good adjusted performance, stable work and high efficiency.
- The tower crane is driven by transition three-speed motor and smooth shift, realizes light-load with high speed, heavy-load with low speed, and its Max. hoisting speed is up to 80m/min. The starting and braking of the hoisting gear is smooth and reliable by using hydraulic brake.The trolley travel on the level jib is dragged by traction trolley with good installation performance.
- Slewing gears adopts vertical planetary reducer, equipped with the fluid coupling, and winding multi-stall speed motor program, disc electromagnetic broker, all make the starting and braking of the hoisting gear is smooth and reliable.
- It has large scope of work, more work methods, wide application.
- The tower crane can get four work methods including rail travel, pressure independent fixed, non-pressure independent fixed and attached outside of the building by changing or adding some spare parts and assistant equipments, which can meet the different requirements.
- The Max. hoisting height of attached tower is up to 200m. The tower can be installed directly on the ground or the concrete foundation near to the building. In order to reduce the tower length and guarantee the tower design ability, we have four attached equipments.
- When the tower independent fixed works, Max. hoisting height is 41m. The tower has two jib length combination, 45m and 50m, which can meet different requirements.
- All kinds of safe equipments, and all work body with brake guarantee the safe and reliable work.safety devices: lifting height limiter, trolley travel limiter, hoisting moment limiter, hoisting load limiter, and slewing limiter.
- The whole machine has reasonable structure and fine shape.The cab is side set independent with wide vision, supplying better work environment for the operator.
- The hanging jib is equipped with rigid double-rod support, and light structure.
- The tower is applied with electrical components produced with advanced technology abroad, reliable quality, long life, less fault, convenient using and simple maintenance.
tower crane Applications:
- With the above features the tower is suitable for such high tower building as middle and high –storey hotels, residential lodgings, industrial building, large span factory, large chimney and silo using synovial method.
tower crane Installation:
- When the installation space is enough, the installation of the tower crane only realized with 16t auto crane, which is convenient and fast.
