subject: Excavator Operation [print this page] Crawler excavator transfer site, application flat trailer transport. Special circumstances need to transfer, must remove the counterweight, the driving wheel in the back, arm, bucket slewing mechanism should be in the braking position and fixed with insurance. Walk every500~1000m to walk the institutions to carry out inspections and lubrication.
Walking excavator and operation sites such as the ground soft, should be the pad to tie or pad. Swamp area must as roadbed treatment or replace a special track plate.
Forbidden mining without blasting of rock or soil above grade five.
Single bucket excavator shovel operation, except for the loose soil, the surface should not exceed the specified maximum performance for excavation height and depth. In pull shovel or backhoe excavator operation, from the work surface edge should be at least keep1~1.5m safe distance.
Checking before starting work device, walking mechanism, the safety protection device, hydraulic components and electrical devices, confirm complete, can start.
Operation area should be no pedestrians and obstacles, mining before chirp schematic, and try to dig several times, to confirm the normal, to begin operations.
When operating, excavators should maintain the horizontal position of the walking mechanism, braking, and the tyre or caterpillar wedge.
In larger hard stones or obstacle, must be removed, before mining. Do not use bucket broken stone, frozen or unilateral bucket tooth gnaws hard.
Mining cliff should take protective measures. Face shall not have umbrella long and loose stones, such as the discovery of landslides risk should be treated immediately or be evacuated to safety of excavator.
When in operation, must be stopped after the fuselage when the bucket digging, not leaving the work surface may be turned to go back, and other movements, brake, should use the slewing brake, shall not use the steering clutch braking.
When loading, bucket to sit as low as possible, not any part of an automobile collision. The car did not stop or bucket must be over the cab while the driver did not leave shall not be loading.
When operating, bucket lift, drop not too hard. Fall not collision frame or track.
In operation or when walking, close to the forbidden overhead transmission line, mechanical and overhead transmission lines safe distance shall be in accordance with the relevant provisions of chapter fourth of the first section of the.
The operator cab off, regardless of the length of time, must take the bucket floor.
When walking, driving wheel in the back, arm and track parallel, brake the slewing mechanism, from the ground about 1m bucket. On the slopes shall not exceed the machine allows maximum gradient. Slope with slow speed, is strictly prohibited in the ramp shift and free sliding.
