QTZ63(PT5013) topless tower crane

Max. Load: 6t
Tip load: 1.3t
Jib length: 50m
Free standing height: 40m
Max. Height: 150m

It's an ideal engineering machinery for construction enterprises for its advanced parameters, excellent and reliable performance, beautiful sculpt, polish quality, simple and practical structure, and also its rational price. It has advanced safety settings, can be used safely and maintained conveniently.

Reduce requirements of lifting equipment when install and dismantle tower cranes. Because there's no tower head, its unit quality is small, installing height is low, max. Installing height is lower 10m than same loading topkit tower crane. For topkit tower cranes, when assemble hoisting jibs, have to joint all jib frames, pulling rods and other accessories on the ground, then will be lifted compeletely, so that will need large capacity lifting equipment. Because connection of jib tip hinge pins, then can lift hoisting jib to connect pulling rod, easy to cause accidents. However, flat top tower cranes won't have such condition. Hoisting jibs of flat top tower cranes are 4m, 5m or 10m per section, take 50m jib as an example, its unit quality is 1/5 of whole jib, can be installed and dismantle in the air, that reduce requirements of lifting equipment when install and dismantle, can save freight of installing and dismantling, safer and quicker.

Suitable for tower cranes group cross operation on the same construction site. Because no tower head, cross height can be reduced to 3m when two tower cranes cross operation, topkit tower cranes needs 10m at least. Less time of installing, lower capacity requirement of lifting equipment, less ballastings, smaller tower body and chassis.   table I  2 falls
