Lifting system
Latch barrel with inner mounting bracket locker is mounted to an underside of the mast-top pulley assembly. Furthermore, all steel cables are not exposed and more effectively protected.
Latching mechanism latched on steering arms is able to release strain on steel cables when in the operation position. The process of latching on and off is stable and without vibration.
The bumper is designed on the luminary mounting bracket for avoiding direct damage between mast-top assembly and the raising luminary mounting bracket.
The leveling device for luminary support bracket is easy to operate and convenient to adjust level.
Special designed red-flag indicator has obvious visual effects and reflects actual situation of latching operation.
