Traits of QTZ40 Tower Crane
1. QTZ40 tower crane is a new designed self-erecting top slewing tower crane. It has various working ways, stationary, external climbing and inner climbing types, is widely used in differernt construction sites. The static height is 29m, it can reach up to max. height of 120m by increasing mast sections and anchorages.
2. It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which enables heavy load low speed and light load high speed.
3. The range-changing structure drives the dolly to change range on the horizontal arm, wih good positioning performance, Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, so high loading capacity, steady starting and reliable operation are realized.
4. The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good version field. It creates a good working environment for the operator.
Fast Erection:
- Assembling is extremely fast and easy, and specifically conceived to guarantee safety conditions during all operations.
Work Safety:
- Fast erecting Topkit Tower Cranes are designed and manufactured to guarantee the highest safety standards during every assembling and working activity. The hinges coupling to the centre plate allow the jib and counter-jib to mesh without dangerous adjustments being required.
- The lifting, slewing and distribution mechanisms are strong, simple and reliable, all controlled by a frequency inverter that give smooth and fast movements, avoiding to overstress the crane structure.
Easy Transport:
- The modularity of its components makes it extremely easy and safe to transport, by keeping the required numbers of means of transport to a strict minimum.
Topkit Tower Crane Characteristics:
- Stable Quality
- Reliable Performance
- Low Rate of Maintenance
- Easier Installation & Dismantling
