The loader may be towed by a 20-ton towing tractor for transportation. The method is
detailed as follows.
Firmly connect the towing tractor to the towing pin of the loader.
The towing tractor shall be equipped with the brake system with good performance.
Place the bucket at the transportation position.
All actions shall be slight and smooth when starting up or stopping the loader, and
brake shall be applied before going down along a slope.
NOTE: When applying the brake, be sure to brake the towing tractor firstly, and then
brake the loader.
4.4.3 WORK METHOD
V-type work method
Align the loader with the material pile, keep the included angle between the truck and
the travelling direction of the loader at 60°, and stop the loader about 12-15m away
from the material pile. After the bucket is filled with materials, make the loader travel
backwards until it is 12-15m away from the material pile. Therefore, turn the loader
and drive it towards the truck and at the same time lift up the bucket. After the
materials are discharged, return to the original position for the next shovel-loading
operation.
Shuttling work method
The shuttling work method is mainly used for the combined work of loader and truck
fleet. As indicated in the figure below, after the loader is loaded with materials, it will
travel backwards by 2-3 times the width of the truck. Thereafter, the truck will run
along one side of the loader and stop in front of the loader. The loader will go ahead
and raise up the boom. After the materials are discharged, the loader will travel
backwards to the original position. If the truck is not fully loaded, the truck will go
ahead by the width of the truck. After completing the next shovel-loading operation,
the loader will return to the original position, and then the truck which is not fully
loaded will travel backwards until it is in front of the loader, and now the loader will
discharge the materials onto the truck. Repeat this operation until the truck is fully
loaded, and then load the next truck. This working method requires the close
cooperation between the loader driver and the truck driver, and, if necessary, the use
of horn, light or gesture for communication.
