Scissor lift trucks are often used for the lifting operation of high-altitude cargo or the lifting operation of personnel. In such an environment, the safety performance of scissor lift is the most important guarantee for lifting freight elevator operations, and the safety performance of scissor lift trucks is There is a close relationship between mechanical safety and proper operation.
Copper Shot is common used Metal Abrasive on copper casting parts like copper valve, electrical accessories, copper watch accessories for surface treatment of deburring. In addition, they could also make them have a matte surface.

Safety performance
Lifting lifts are equipped with safety devices for traditional traction elevators. They are also equipped with: Relief valves: to prevent excessive system pressure during upward movement. Emergency manual valve: When the power supply fails, the car can be lowered to the nearest emergency. The door of the floor opens the door and the hand pump: when the system fails, the manual pump can be operated to press the high pressure oil to lift the car to the nearest floor position; the pipeline rupture valve: when the hydraulic system pipeline ruptures, the car stalls, Automatically shut off the oil line to stop falling. Oil tank oil temperature protection: When the oil temperature in the oil tank exceeds the standard setting value, the oil temperature protection device generates a signal and suspends use of the elevator. When the oil temperature drops, the elevator can be started.
Precautions
Judging from the safety performance of the machinery itself, there are no major safety issues after national safety certification. The main problems are concentrated in the fact that mechanical components are detached or damaged due to various factors after the lift lifts are used for a period of time. This problem depends on the regular inspection and maintenance of machinery.
The improper operation is the most important factor for the failure of the scissor lift truck. When the lift truck stacks the goods, it should be stacked neatly, and it is best to pile up in the center of the freight elevator cargo stacking area to avoid unbalanced ends of the stacking cargo area. Eventually when upgrading the freight elevator operation, the upgraded freight elevator loses its balance. After the cargo is stacked, it is best to use a rope to lock the cargo, so that the cargo is not afraid of being “accidentally†scattered during the lifting process.
