Before Operation
LOW SPEED MODE—WINCH
CONTROLS UNLOCKED – Pull the speed/lockout
control le
ver back for the hook winch low speed
range, maximum hook winch pull is available; the
boom winch speed unaffected.
Speed/Lockout Control Lock (2)
Use the speed/lockout control lock lever (2) to lock
the speed/lockout control lever (1) in the LOCKED
MODE position.
Move the boom control lever to HOLD position.
Move
the hook c
ontrol lever to HOLD position. Move
the speed/lockout control lever to the centre
position. Flip the speed/lockout control lever over the
control lever in order to lock the lever in the LOCKED
MODE position. This locks the boom controls and
the hook controls in HOLD in order to prevent
accidental boom movement or hook movement.
Flip speed/lockout control lock away from the speed/
loc
kou
t control lever in order to allow actuation of the
speed/lockout control lever. Move the speed/lockout
control lever to the desired speed range in order to
operate the winches.
Always move the speed/lockout control lever to the
"L
OCKED"
position before shutting off the engine or
immediately after the engine quits running to prevent
unintentional load release or--after the engine is
restarted-- unintentional drawworks operation.
Hook Control (3)
HOLD – : The lever self centres to this
position whenever it is released. In this position, the
load winch brak
e will set, and the hook will stop and
remain at the position it is in.
Component failure! Re-engaging the free fall
while the load is dropping causes shock loads
which could cause component structural failure,
resulting in possible personnel injury or death.
(Emergency Lower) Free Fall – l- Move the
hook control lever to this position to lower the load
fast in an
emergency. The load winch’s free fall brake
will release, and the hook will move down under the
weight of the load. The lever will return to the “HOLD”
position when released, the load winch’s free fall
brake will; upon activating the free fall function the
load will drop and must be allowed to fall to its end
travel without re-engagement.
NOTICE
The Free Fall is used for a full release of a
suspended
load up to the maximum lift capacity of
the hook winch. Upon activating the free fall function
the load will drop and must be allowed to fall to its
end travel without re-engagement.
Note: Free Fall is only available in pipelayer HIGH
or LOW SPEED modeæWinch Controls Unlocked.
LOWER: – Move the lever to this position to
lower the hook with controlled winch power. The
furthe
r the lever is pushed away from HOLD, the
faster the hook will lower. The closer the lever is
toward HOLD, the slower the hook will lower. When
the lever is released, it will return to the HOLD
position, the winch brake will set, and the hook will
stop and remain at the position it is in. Hook winch
line speed varies with engine throttle setting. Hook
control is smoothest at engine speeds faster than
idle.
RAISE: – Move the lever to this position to
raise the hook. The further the lever is pulled away
from "HOLD", the fa
ster the hook will raise. The
closer the lever is toward "HOLD", the slower the
hook will raise. When the lever is released, it will
return to the "HOLD” position and the hook will stop
and remain at the position it is in. Hook winch line
speed varies with engine throttle setting. Hook
control is smoothest at engine speeds faster than
idle.
Note: T
he hydraulic pilot system and some machine
controls,
namely the hook quick drop, are "LIVE" for
as long as the accumulator holds a charge, even if
the engine is not running. This pressure charge will
take approximately four hours or more to bleed off.
Refer to the operation and maintenance manual
"Free Fall Active" for dropping load hazard warning.
Refer to the operation and maintenance manual
"Accumulator - Relieving Charge" to bleed off the
residual pressure if required and when safe to do so.
