Towing The Machine - Hyundai HL930A Operation & Maintenance Manual

6. TOWING THE MACHINE

Personal injury or death could result when
towing a disabled machine incorrectly.
Block the machine to prevent movement be-
fore releasing the brakes. The machine can
roll free if it is not blocked.
Except for an emergency, do not tow this
machine. If it is inevitable to tow the ma-
chine, observe the following.
1) GENERAL
(1) The parking brake cylinder of the machine
is operated by the spring force and re-
leased by hydraulic pressure.
If the engine does not operate, the brake
will be operated to stop the machine.
(2) When the machine is towed, move it for re-
pair to a nearby place at a speed less than
2 km/h (1.2 mph). Transport it on a trailer,
if it has to be moved for a long distance.
(3) When the steering device and the brake of
the machine to be towed cannot be oper-
ated, transport by trailer.
Be careful when towing.
Be careful that the brake will not work if there is any disorder in the braking sys-
tem.
(4) When you tow the machine from the front, attach the tow line to the tow eyes on the front
frame (1).
When you tow the machine from the rear, use the tow rear eyes provided for lift & tie (2).
(5) Do not use a chain for pulling a disabled machine. A chain link can break. This may cause
personal injury. Use a wire rope cable with ends that have loops or rings. Place an observer in
a safe position in order to watch the pulling procedure. The observer can stop the procedure,
if necessary. The procedure should be stopped if the cable starts to break. Also, stop the pro-
cedure if the cable starts to unravel. Stop pulling whenever the towing machine moves without
moving the towed machine.
(6) Keep the tow line angle to a minimum. Do not exceed a 30 degree angle from the straight
ahead position.
(7) Quick machine movement could overload the tow line or the tow bar. This could cause the
tow line or the tow bar to break. Gradual, steady machine movement will be more effective.
(8) Normally, the towing machine should be as large as the disabled machine. Make sure that the
towing machine has enough brake capacity, enough weight, and enough power. The towing
machine must be able to control both machines for the grade that is involved and for the dis-
tance that is involved.
