6.3 Winching and Towing
Procedures
This section provides the operator with the winching
and towing procedure, which includes instructions on
how to manually release the brakes.
WARNING
Ensure boom is in stowed position before
winching or towing. Sudden motion could cause
MEWP to become unstable. Death or serious injury
could occur.
WARNING
In emergency situations where MEWP functions
are not available and lowering is impeded by an
obstacle, utmost care must be taken to move
MEWP far enough to clear obstacle. In such cases,
operation must be extremely smooth with no
sudden movements and must not exceed a speed
of 50 mm/sec (2 in/sec).
WARNING
When winching or towing, do not exceed 3.2 km/h
(2 mph).
WARNING
Do not winch or tow MEWP on grade steeper than
45%.
WARNING
Do not winch or tow MEWP onto a slope, or brake
the towing vehicle rapidly. Do not pull MEWP down
an incline towards a winch.
1. Before winching or towing MEWP, fully retract,
lower and position boom over rear drive wheels
in line with direction of travel.
2. Manually release brakes (refer to Section 6.3-1).
3. Remove wheel chocks or blocks, and then
winch or tow MEWP to desired location.
4. Position MEWP on a rm and level surface.
5. Chock or block wheels to prevent MEWP from
rolling.

of the drive pump. Re-engage the drive pump
