Lifting system

Latch barrel with inner mounting bracket locker is mounted to the underside of the pulley assembly at the top of mast. Furthermore, all steel cables are not exposed in the air, which realizes more effective protection.

Latching mechanism latched on steering arms is able to relieve strain on steel cables during working condition. The process of latching on and off is stable and non-vibrating. 

The bumper is designed on the illuminant mounting bracket to avoid direct damage between mast-top assembly and the illuminant mounting bracket.

The leveling device for illuminant support bracket is easy to operate and convenient to adjust level.

Special designed red indicator is with obvious visual effects to reflect real-time situation of latching operation.

Other models can be customized according to clients' requirements.
