Under normal working conditions, equalization valves (8)
and emergency lowering valves (9) are closed. Oil flows to
the lower chamber of master cylinder through check valve
and the force of the piston causes the oil in the upper
chamber of the master cylinder to flow to the slave cylinder,
so the two platforms go up equally. The flow of oil from check
valve to the slave cylinder is blocked by equalization valves
(8).
For emergency lowering, open 2 emergency lowering valves
(9) to lower the lift slowly and carefully. The lowering speed
can be adjusted by speed valve (11).
To equalize two platforms, open 2 equalization valves (8),
raise the lift up and down 1 or 2 times and firmly closed
valves (8).
