Platform Lift Circuit
Note:
Refer to Hydraulic Manifold and Relief Pressure Adjustment Procedure.
Refer to Section 7 for Remove and Install instructions.
On model 3084RT, the lift system uses the hydraulic pump to obtain proportional lifting function
controlled by the lift valve and proportional valve.
On model 3084ES, the lift system uses the electric motor to obtain proportional lifting function
controlled by the lift valve.
Lowering is single speed. When lowering, the holding valve on the lift cylinder opens allowing gravity
to lower the platform. Lowering speed is regulated by a fixed orifice located on the lift cylinder.
ANSI:
Platform capacity is limited by a hydraulic relief valve in the lift circuit. (Refer to Machine
Specifications or the Hydraulic Schematic for proper setting).
CE:
Lift capacity is controlled by the Overload System.
