MAINTENANCE OF FORKLIFTS - OD1660 - LESSON 1/TASK 2
(d) Tow Bar. The tow bar (figure 18 on the previous page) is
constructed of heavy-duty steel and is normally stowed in the
vertical position together with the retaining pin. It pivots to the
horizontal position to connect the forklift truck to the towing
(e) Pintle Hook. The pintle hook is a manually-operated latch-
type rigid pintle. It is opened by removing the cotter pin, pulling
the latch handle to the rear and lifting the top jaw. It accepts a
standard 3 inch by 1 5/8 inch lunette for connecting the towed load
to the forklift truck.
These are constructed of steel links with
attachment hooks to provide additional connection (safety) between
the forklift and the towed load or the towing vehicle.
(g) Steering Bypass Valve.
This valve is mounted on the left
side of the operators seat.
By turning the valve handle
counterclockwise, it disables the steering system and allows the
front chassis to pivot freely about the rear chassis and the steering
and must be closed (turned fully clockwise) for normal steering and
(h) Axle Disconnect Lever. This lever is used to disengage the
Pulling the lever outward allows the transmission output
shaft to freewheel, and prevents transmission damage or wear while
towing. The lever must be pushed inward for normal truck operations.
(12) Mast Assembly.
The mast (figure 19 on the following page)
raises and lowers the carriage by means of lift chains.
height (height of the forks without increased mast height) is not
less than 48 inches.
It consists of the outer and inner mast and
includes the mast latch pin. This pin is used to latch the outer and
inner mast between zero and 12 inches height of the lifting forks.
It disengages at over 12 inches height of the lifting forks. It also
ensures free travel of not less than 48 inches.
functions essentially the same
as the 6000 pound forklift.
Therefore, in this task, all controls and components will not be
