PRODUCT DESCRIPTION

The GHS Hydraulic Platform Lift is an electric/hydraulic system designed to safely lower your swim
platform below the water surface in order to launch various watercrafts. Your yacht builder has designed
and strengthened the transom of your yacht to allow the GHS Hydraulic Platform Lift system to be
attached to the transom and to operate with very specific maximum loads. Make certain that you consult
your yacht "Owners Manual" for this information. Operating the Lift outside of the designed maximum
limit may result in STRUCTURAL damage to the transom.
The Platform Lift System consists of the following major components:
A Power Unit Assembly
B Platform lift assembly
C Control Unit
The Power Unit Assembly is an integrated unit combining a 12V DC or a 24V DC electric motor, a
hydraulic pump, a hydraulic manifold, a manual hydraulic pump and the necessary valves and relays to
allow the unit to function. The hydraulic manifold is a complex unit that routes and controls the flow of
fluid to the four hydraulic cylinders. All of the valves in the manifold are preset at the factory to function
at very precise pressures and are not to be adjusted in the field by anyone other than a factory authorized
representative. Any readjusting of these valves by someone other than an authorized representative will
void the warranty on the entire Lift Assembly and may cause serious damage to the lift and the vessel.
The Platform Lift Assembly consists of the following major components:
A Transom Brackets
B Platform Brackets
C Lift Cylinders
D Locking Cylinders
E Lift Arms
The above components are designed to act as one unit to allow hydraulic pressure to lower and raise the
swim platform under controlled conditions. Extreme caution must be exercised when this unit is moving
either up or down. The locking and lift cylinders are very powerful, operating pressures as high as 2500
PSI. A warning horn signals when the platform is moving in either the up or down direction to caution all
in the vicinity that the platform is moving and all should remain clear. The lift should never be operated
when personnel are on the platform.
The remote control unit is a hand-held UP/DOWN switch that is hard-wired to the Power Unit Assembly
through a disconnect mounted in the vicinity of the transom. In addition to the standard hard-wired
control, there is available an Optional Radio Remote Control that can operate the platform lift from
distances of approximately 60-100 feet.
