reliable quality and safety guarantee., manufacturer of tower crane with 10-year-experience., we have BV certification. - details see: https://www.machineto.com/5t-hydraulic-self-erecting-contsruction-tower-crane-qtz63-tc6310-10103527

QTZ tower crane is famous for its large operate ranges, varied working methods and wide uses.CCBT QTZ Tower crane is designed according to the standard of GB/T5031-2008” classification of tower crane”

The crane has many working mood, it is used in different condition, such as: anchored by embeded bolts, anchored to the building and so on. So that it is applied in different construction projects.

Advantages are as follows:

1.The technology of three mechanism keeps the most advanced level in China.

2.Hoisting, slewing and trolley mechanism adopt the frequency conversion.

3.Stable starting and braking, mall impact.

4.Long time Low-speed running and accurate positioning.

5.PLC programmable intelligent control system with top-brand electrical components.

6.Visual system(Alternative): in focus=safety+efficiency

7.Fastener galvanization against rust.

This series of tower crane has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, it shows a good speed-control capacity, satisfactory operating stability and high work efficiency. It can be widely used for the construction of high-rise hotels, residential buildings, high-rise industrial buildings, large-span factory buildings and tower-like buildings, like chimneys.

It has high working speed, good regulated speed performance, high efficiency, works smoothly and reliably. Hoisting mechanism has achieved a heavy low-speed, high-speed light-load. The trolleying mechanism have three kinds of speed to meet the operational needs; slewing mechanism have open-type stopper, it is easy for standard place and for the safety working.

All equipped safety devices are complete, such as weight limiter, height limiter, radius limiter, slewing limiter, rope-break-proof device, axle-break-proof device, slewing brake, traction brake and similar safety guards. Which are mechanical or mechanical-electrical integrated products and adopt to all badly conditions to ensure the crane working reliably.

We also provide excellent after-sales service which will get rid of all your worries in the purchase of our products.
