Tower Crane series 返回
key stressed parts of the metal structurebrake motorhydraulic coupler
[Assembly]
Turning gears all adopt a hydraulic coupler, simple and reliable, able to accelerate and decelerate very steadily, also avoiding motor overloading;
All key stressed parts of the metal structure are made of 16Mn low alloy steel;
Amplitude variation mechanism composed of double coil three speed brake motor, planetary reduction gear and door restrictor, easing maintenance and reducing fault rate.

Scope of application: construction of high-rises and building complexes


[Characteristics]
Light overall structure, artistic appearance, wide operating range, high performance, safe and reliable;
Equipped with many safety devices, including moment restrictor, weight restrictor, height restrictor, amplitude restrictor, reverse stopper;
Air-conditioned driving cab, steadily operating frequency conversion mechanism without shock;
The electric control system may be provided with all imported component;
This unit may be combined into track travelling type, fixed type, attached type or internal climbing type;
Fitted out with remote control device at user's option;
