Loading, unloading and transportation of machines
1. Safety rules for the shipment of the machine
1) Run the engine at a low speed, and operate the machine slowly when loading/unloading.
2) Do not load/unload the machine during automatic warm-up operation.
3) If the automatic warm-up operation is cancelled during the loading/unloading operation, the speed
will suddenly change.
4)
When loading/unloading the machine, choose a solid and level ground. Keep a safe distance from the edge of the
road.
5) To use a ramp with sufficient width, length, thickness and strength, the width of the slab is 1.2 to
1.5
times of the track width. In order to avoid any accidents, it is recommended that the loading/unloading slope should
be less than
15°, or the length of the slope should be greater than 3.5
times of the height. When using a
mound slope, the mound shall be completely compacted and measures shall be taken to prevent the slope from
collapsing.
6)
In order to prevent the machine from slipping on the ramp, remove all the mud and dirt on the track before starting.
Make sure that the surface of the ramp is clean and free of water, snow, ice, grease or oil.
7)
Do not correct the steering on the ramp, otherwise, the machine may tip over. If you must turn, you should drive off the
ramp, correct the direction, and then enter the ramp.
8) Do not use working devices for loading and unloading operations, this is dangerous.
9) When on a ramp, do not operate any joysticks other than the walking joystick.
10)
At the junction between the ramp and the transport vehicle, the center of gravity of the machine will suddenly change,
and there is a danger of the machine losing its balance. Therefore, walk slowly when crossing this area.
11) When turning the upper structure on a transport vehicle, the transport vehicle is unstable.
Therefore, retract the working device and rotate slowly.
12) No matter whether the machine is getting on or off, the wheels of the transport vehicle should be
wedged.
13)
Use wooden wedges to keep the excavator in a fixed position on the transport vehicle during transportation. Tie the
excavator to the transport vehicle with a rope.
14)
Before the driver leaves his seat after completing the work or ending the maneuvering. Raise the left control box first,
so that the pilot control oil circuit is disconnected, in order to prevent the machine from malfunctioning due to mistakes or
accidental hitting of the joystick.
15) Before going up and down the ramp, be sure to put down the positioning handle of the rotation
platform to prevent the platform from slewing.
