Roped hydraulic elevator motor
Roped hydraulic elevators remain uncommon, but have gained favor in recent years because they allow the hydraulic piston to be installed above ground, eliminating the need for costly drilling underground to install a borehole jack. This also makes servicing the piston significantly easier. A warning label instructs anyone maintaining the elevator to take note of this uncommon configuration; it reads:
Warning - Roped Hydraulic - Do not use manual lowering valve if unit is on safeties. Excess slack rope will occur and equipment damage may occur. Do not leave manual lowering valve in open position. Excess oil may flood tank.
