4.10 TIE DOWN AND LIFTING
When transporting machine, boom must be in the stowed
mode with turntable lock pin engaged and machine
securely tied down to truck or trailer deck. Four tie down
eyes are provided in the frame slab, one at each corner of
the machine. (See Figure 4-3. Machine Tie Down.)
If it becomes necessary to lift the machine using an over-
head or mobile crane, it is very important that the lifting
devices are attached only to the designated lifting eyes,
and that the turntable lock pin is engaged. (See Figure 4-
4. Lifting Chart.)
NOTE: Crane and lifting devices, chains, slings, etc., must
be capable of handling at least:
600SC - 9,979 kg. (22,000 lbs.)
600SJC - 10,660 kg. (23,500 lbs.)
660SJC - 12,247 kg. (27,000 lbs.)
ABOVE ARE MINIMUM WEIGHTS. CHECK WEIGHT OF UNIT
PRIOR TO LIFTING.
NOTE: Lifting eyes are provided at the front of the frame
slab. An optional lifting attachment is required at the
turntable end. Each of the four chains or slings used
for lifting machine must be adjusted individually so
machine remains level when elevated.
SECURE TURNTABLE WITH TURNTABLE LOCK BEFORE TRAV-
ELING LONG DISTANCES OR HAULING MACHINE ON TRUCK/
TRAILER.
4.11 TOWING INFORMATION
Towing the Machine
PERSONAL INJURY OR DEATH COULD RESULT WHEN TOWING
A DISABLED MACHINE INCORRECTLY.
BLOCK THE MACHINE TO PREVENT MOVEMENT BEFORE FINAL
DRIVES ARE DISENGAGED. THE MACHINE CAN ROLL FREE IF IT
IS NOT BLOCKED. WITH FINAL DRIVES DISENGAGED, THE
MACHINE CANNOT BE STOPPED OR STEERED.
FOLLOW THE RECOMMENDATIONS BELOW, TO PROPERLY PER-
FORM THE TOWING PROCEDURE.
RELIEVE THE HYDRAULIC TANK AND LINE PRESSURE BEFORE
ANY DISASSEMBLY.
REMOVING THE PLUGS FROM THE BRAKE COVER OF THE
TRAVEL MOTOR WITHOUT FIRST RELIEVING THE INTERNAL
PRESSURE WILL CAUSE HYDRAULIC OIL TO SQUIRT OUT.
EVEN AFTER THE MACHINE HAS BEEN TURNED OFF, THE
HYDRAULIC OIL CAN STILL BE HOT ENOUGH TO BURN. ALLOW
THE HYDRAULIC OIL TO COOL BEFORE DRAINING.
NOTE: To tow the machine, both final drives must be disen-
gaged.
NOTE: Do not operate the travel motors with the final drives
disengaged. Damage could result.
These towing instructions are for moving a disabled
machine for a short distance at low speed. Move the
machine at a speed of 2 km/h (1.2 mph) or less to a con-
venient location for repair. Always haul the machine if long
distance moving is required.
Shields must be provided on both machines. This will pro-
tect the operator if the tow line or the tow bar breaks.
Do not allow an operator to be on the machine that is
being towed.
Before you tow the machine, make sure that the tow line
or the tow bar is in good condition. Make sure that the tow
line or the tow bar has enough strength for the towing pro-
cedure that is involved. The strength of the tow line or of
the tow bar should be at least 150 percent of the gross
weight of the towing machine. This requirement is for a
disabled machine that is stuck in the mud and for towing
on a grade.
Attach the cable to the towing eye on the front of the
machine if you are towing the machine forward. Attach the
cable to the towing eye on the rear of the machine if you
are towing the machine backward.
