WARNING

Should the vehicle be fitted with a tailgate. Cohesive material must not

be loaded into the body. There is a risk of injury to the driver if a tailgate

is used with a cohesive material.

Note: When loading the operator should be diligent and always aware of the

material which is to be loaded onto the vehicle. At any time, should he feel that a

load constitutes an obvious safety hazard, he has the right and duty to refuse to

load this onto the vehicle.

The most common methods of loading articulated trucks are with hydraulic

excavators, and front end loaders. The trucks can be loaded equally well from

the rear or the side using hydraulic excavators or rope shovels. Ideally,

excavators should require 90° or less swing. With a backhoe excavator a very

efficient loading method is with the backhoe on top of the bank loading over the

rear of the truck at the base of the bank. Backhoe slew angles can be small,

leading to very short cycle times.

WORKING THE TRUCK

Off-highway articulated trucks are used on a variety of hauling jobs, from sand

and gravel pits to road construction and mining. Every truck operation,

regardless of the type of job, can be divided into four phases; loading, hauling,

dumping and the empty return.

Note: After coming to a stop for loading or unloading the truck, the parking-

emergency brake control can be pushed in to hold the brakes in the applied

position as though the foot brake is depressed.
