·Hydraulic synchronization by four cylinders. The mechanical safety locking unit automatically releases before descending.

·Safe low control voltage (24V) for all control buttons and switches.Constantly read the height and working status of each platform throughvisual monitor.

·CLOSED-LOOP control system, the two platforms automatically align witheach other during every rising and lowering cycles. in normal working, theheight deviation is limited within 20mm.
·The lifting system stops working in case that the height deviation exceeds 20mm.
·At most 6 platforms can work together synchronously.
