1.The Limit device is for Automatic alarm at the limit position
2.The booms’ rotation is controlled reliably. The booms can be guaranteed to stay at any position, even on a slope. There is also the manual rotary device can also manually rotating the engine or hydraulic system failure.
3.The working platform is with the automatic leveling function. The tilt angle, which is for the working platform relative to a horizontal, can not be greater than 1.5 °.The working platform with manual leveling, that allows the working platform rose at an angle to meet specific work.
4.The ground and platform’ control boxes with emergency stop button. when the operation in accident, the operator can quickly extinguished the engine to avoid the platform to continue to make movement
5.With manual emergency pump or the optional 12V auxiliary electric power plant, the working platform can secure to the ground when the engine or main pump failure.
6.With horizontal instrument, when the machine is parked in the irregularities of more than 3 ° to the ground, the operator is able to observe.
7.The 2 control boxes are with protective covers.
8.The head of booms and Cylinder Piston Rod are with dust proof’s device.
9.Safe valves are installed in hydraulic circuit that will prevent the abnormal elevation of the pressure in the hydraulic components.
10.Each cylinder has a balancing valve or hydraulic lock that assures that the cylinders don’t make movement automatically. And the connection is rigid between cylinder, balance valve and hydraulic lock, that fully guarantee the cylinder does not automatically retracted and "soft legs".
