CHASSIS
Welded Steel Structure.
DRIVE UNIT & TRANSMISSION
24V DC drive motor with two stage speed reduction by Chain & Sprockets, transmits power to drive wheels. The entire unit swivels on heavy duty ball & roller bearings and is controlled by a steering handle.
ELECTRICAL SYSTEM
Two sets of microswitches are provided for forward / reverse control. Located on top of the steering handle and operated by ush buttons, these microswitches acactuate the forward/reverse contractors. The 1st stage of traction is through a resistance, which is cut off in the 2nd stage by a third contractor, actuated by pressing the push buttons little further. For energising the hydraulic pump, a separate contractor is provided which is actuated by the hydraulic control lever, through a microswitch.
BATTERY
24v, lead acid fraction battery, capacity 224 AH @ 5 hrs rate of distance at 30ºC is provided.
TESTING & HYDRAULIC SYSTEM
A hydraulic pump is coupled with a 24V, DC motor which is actuated by a microswitch attached with the hydraulic control lever through a contractor. The lever operates a hydraulic fluid. The control valve is provided with pressure felief valve, which protects the system from overloading.
The pressurised fluid is fed to the Lift Jack, which, in turn, raises the fork carriage through a chain & pulley arrangement. A safety flow control valve is provided at the base of the lift jack, which prevents loads dropping at high speed, in the event of a hydraulic pipe burst.
CONTROLS
The steering control handle is spring loaded on as to return to vertical position always. A mechanical brake arrangement is provided, which becomes effective when the handle is either in vertical or horizontal position.
Forward/Reverse push buttons are provided on top of the handle. For Hurraulic Controls, a self centering three position lever is provided for lift/nertral/lower.
MAST UNIT
A twin telescopic welded channel mase-unit, comprising one Inner Mast, with a welded steel fork carriage is used for lifting operation. Forged guide rollers, mounted on ball bearing are provided for free movement. Nylon adjustment thrust pads are also provided for absorbing side thrusts.
FORKS
They are manufactured in parts from forged alloy steel and can be adjusted sideways on fork carriage and is provided with a locking device.
WHEELS
1. No rubbrerised drive wheel and 2 no rubbrerised load wheels are provided.
