Scissor lift emergency system
Caused due to certain circumstances when the hydraulic system parking are working at height safety personnel and equipment needed return to the ground, we set up a decentralized system to scissor lift the emergency systems. Mainly by the high-pressure shut-off valves, Usually they are in the OFF state, to maintain the normal operation of the system when a fault occurs, first open the shutoff valve by hand number. then use the weight of the boom and the resulting load-driven workbench luffing cylinder rod chamber to produce oil. Since the cut-off valve is turned on, direct drive hydraulic telescopic cylinder piston forced to retract the telescopic boom cylinder is retracted so. retract the use of shut-off valves open and close to control the speed of the boom retracted. then wait for the boom fully retracted after Road closed valve, globe valve to control the opening and closing by luffing cylinder retraction alone, so boom lifts the hem until completely dropped to a safe location. then all closed valve, the system has returned to its original state, such as when the system is repaired, Restart the system, but also scissor lifts work.
Now, all aspects of technology matured scissor lift, scissor lift the related technology is constantly improving, I believe the scissor lift will get more user acceptance and favor.
