Series D Lift with access from a mezzanine

Hydraulic Vertical Lifts - D Series Specifications


The D Series moves materials between two levels. Principal components are guide columns, carriage and hydraulic actuating mechanism.


Lifts loads up to 4,000 lbs. Carriage sizes up to 6’ x 6’. Vertical rise to 15’. Standard travel speed is 17 FPM (up to 25 FPM available).


Guide columns are 6” wide flange sections. Carriage is fabricated of heavy-duty structural members with steel deck plate. Other deck surfaces can be supplied. Carriage is cantilever style and may be loaded from any one of three operating sides depending on application.


Carriage is lifted and lowered by direct-acting hydraulic cylinders. Cylinders are actuated by a remote mounted hydraulic pump. Transmission of the lifting force is direct from the base of the guide columns to the carriage using a Dual-Pak ram.


Standard power requirements are 208/230/460VAC, 3-phase (single-phase available). Control voltage is 24VAC. Push button stations are NEMA 12 rated. Pump mounted, pre-wired control panel is NEMA 12 rated. Push button stations are provided for each level  and include call/send operators and a mushroom-head emergency stop. Quick connect pre-wiring is available (optional).


Upward travel of the carriage is limited by positive mechanical stops that ensure positive leveling with the upper deck. Redundant overload protection is provided to positively prevent raising of the carriage if loaded to more than 120% of rated capacity. Velocity fuses prevent uncontrolled descent in case of hydraulic hose rupture. NO RIDER signs are posted at each point of operation. 


Carriage is equipped with safety rails on non-operating sides and safety chains or diagonal drop bars on operating ends. Optional expanded metal or sheet metal carriage side guards are available.


Safety codes (ASME B20.1) require interlocked gates and enclosures on all sides of the lift. Enclosures must be a minimum of 8’ high and reject a ball 2” in diameter.
