A03030 3/06 General Safety And Operating Instructions - Komatsu 830E-AC Shop Manual

TOWING
Prior to towing a truck, many factors must be care-
fully considered. Serious personal injury and/or sig-
nificant property damage may result if important
safety practices, procedures and preparation for
moving heavy equipment are not observed. DO NOT
tow the truck any faster than 8 kph (5 mph).
Attachments for towing the 830E are available from
Komatsu distributors as follows:
Front Bumper Modification Kit - XK0309: This kit con-
tains the parts necessary to modify the front bumper
for installation of towing bosses. One XK0309 kit is
required for each truck in the fleet.
Tow Adaptor Structure - MK3945: This structure
must be ordered (or designed) to mate with the
intended towing vehicle and is intended for towing an
unloaded vehicle only.
A disabled machine may be towed after the following
minimum precautions have been taken.
1. Shut the engine off.
2. If equipped, install hydraulic connections for
steering and dumping between the tow vehicle
the and disabled vehicle. Check the disabled
vehicle braking and steering systems for normal
operation.
3. If the disabled truck is loaded, dump the entire
load. Never pull or tow a loaded truck.

4. Inspect the tow bar for adequacy. The bar must
be approximately 1.5 times the gross vehicle
weight of the truck being towed.
5. Ensure whether the tow vehicle has adequate
capacity to both move and stop the disabled
truck under all conditions.
6. Block the disabled truck to prevent movement
while attaching tow bar.
7. Release the disabled truck brakes and remove
the blocking.
8. Sudden movement may cause tow bar failure.
Smooth, gradual truck movement is preferred.
9. Minimize tow angle at all times - never exceed
30°. The disabled truck must be steered in the
direction of the tow bar.
