Introduction
2-1 GENERAL DESCRIPTION
The model XLT-1071 Cougar Lift is designed and manufactured for use as a warehouse
stocking and order picking machine. Its unique guard rail design permits the operator to
ride on the platform with the load, while transferring it from group level to its overhead
storage location. The maximum platform load is limited to 500 lbs.
Platform elevation is accomplished by means of a 1-1/2 inch displacement type hydraulic
cylinder. The lower telescoping section is pushed vertically upward by the cylinder while
the upper sections are raised by a mechanical motion advantage accomplished through
two sets of chains and sheaves. The platform is raised three inches for each one inch of
cylinder extension. Platform elevation and descent is controlled by pushbuttons on the
upper control box located on the platform.
Safety of operation is assured by proper inspection and maintenance procedures as set
forth in this manual. The possibility of platform free-fall is eliminated by proper mainte-
nance and replacement of the chains, sheaves and sheave pins, a properly installed flow
restrictor valve, and a clean mast. The non-adjustable restrictor valve controls and fixes
the rate of platform descent whether empty or fully loaded to approximately 0.6 feet per
second. A hydraulic hose failure will result in the same rate of descent, eliminating free-
fall, when the restrictor valve is installed properly.
Emergency lowering of the platform is accomplished by means of a manual control valve
located on the hydraulic manifold block assembly, next to the pump/motor unit.
The Cougar Lift features a displacement type of cylinder that will not rust or corrode dur-
ing storage since the cylinder rod is immersed in oil. It is important that the cylinder rod
be kept clean and undamaged for the protection of the cylinder head packing.
The floor lock safety switch prevents the unit from raising until the two floor pads have
been properly engaged and helps to make the Cougar Lift a safe, dependable machine.
Carefully read all the safety instructions contained in Section 1 of this manual before op-
erating the Cougar Lift.
