Technical preparation before hydraulic excavator work 1) The engine section is implemented in accordance with the relevant regulations of the general operating procedures. 2) A signal should be sent before the engine is started or operated. 3) Check the hydraulic system for leaks; the tire type excavator should check whether the tires are in good condition and the air pressure meets the requirements; check the transmission device, brake system, slewing mechanism, instruments and meters, and test run, confirm the normal rear allowable Enter the job status. 4) Learn more about construction tasks and site conditions. Check the solidity and stability of the soil at the excavator's stop. The tire excavator should be supported to maintain its stability and reliability. Check the stability of the roller and groove slope to prevent the excavator from tipping over. 5) Any person in the area is strictly prohibited from staying in the excavator work area. Unrelated persons are prohibited from entering the cab. 6) The excavator work site should have a road for the dump truck to enter and exit. Technical requirements for hydraulic excavator operation and driving 1) When excavator is working, it is forbidden for anyone to push up and down the excavator and deliver the goods. It is not allowed to maintain while working; do not adjust the engine (speed governor) and hydraulic system and electronic control system at will; pay attention to selecting and creating reasonable work. Face, it is strictly forbidden to dig holes. 2) When the excavator is unloading, it should be carried out after the dump truck stops. When the unloading does not collide with any part of the dump truck, the height of the bucket should be lowered; the bucket is crossed from the top of the dump truck cab. 3) It is forbidden to use a bucket to crush solid objects; if large stones or hard objects are encountered, it should be cleaned before continuing to work; it is forbidden to excavate the rock of level 5 or above. 4) It is forbidden to arrange the excavator in the upper and lower excavation sections at the same time; when the excavator moves in the working plane, the ground should be leveled and the obstacles in the passage should be removed. 5) It is forbidden to jack up the excavator by fully extending the bucket cylinder. The excavator cannot travel horizontally or slewing when the bucket does not leave the ground. 6) It is forbidden to use the excavator boom to drag the object laterally; the hydraulic excavator cannot be excavated by the impact method. 7) When the excavator is making a swing motion, the reverse handle cannot be operated in the opposite direction. 8) The driver should always pay attention to the operation of the excavator. If abnormality is found, stop the vehicle immediately and check it out in time. 9) During the operation and operation of the excavator, always check whether the temperature of the hydraulic oil is normal. 10) When the excavator encounters electric wires, crossroads, bridges and culverts, understand the situation and then pass it. If necessary, set a special person to command; the distance between the excavator and the high-voltage electric wire should not be less than 5m; 11) When the excavator is running, its boom should be parallel with the running mechanism, the turntable should be locked, and the bucket should be about 1m away from the ground. The downshift should be used when running downhill, and it is forbidden to disengage. 12) The excavator's walking route should be kept at a sufficient distance from the slope, ditch and foundation pit to ensure safety; when crossing the soft section, use a low-speed uniform speed, and if necessary, use wooden boards, stones, etc. to pave the way. Technical work after hydraulic excavator operation 1) Excavators should be parked in a flat, solid place that does not obstruct traffic, hang upside down and implement parking brakes. If necessary, if parking on the ramp, the wedges are placed on the front and rear of the running mechanism. 2) Turn the fuselage, the bucket is landing, the work device joystick is placed in the middle position, and the driver can leave the excavator after locking the window door. 3) Routine maintenance of the excavator as specified in the warranty procedures. Mobile Scissor Lift traction type lifting platform uses external power as traction and three-phase power supply or diesel engine as power. It is convenient and fast to move and suitable for long-distance operation. It is mainly used for field high-altitude operation in oil, power, urban construction, post and telecommunications and other industries.
Mobile lifting platform is a kind of special equipment for high-altitude operation. Its scissor fork mechanical structure makes the lifting platform have high stability, wide working platform and high bearing capacity, which makes the high-altitude operation range larger and suitable for multiple people to work at the same time. It makes the high-altitude operation more efficient and safe. It is mainly used for indoor and outdoor mechanical installation, equipment maintenance and building maintenance of stations, docks, bridges, halls and plants.
Mobile Scissor Lift product structure is stable, the movement is flexible, the lifting is stable, the operation is convenient, and the load capacity is large.

Hydraulic excavator operating procedures
Hydraulic excavators are currently the most prosperous construction machinery products, but many users do not use hydraulic excavators properly, resulting in damage to the machine due to operational errors. The technician said that the operator must clearly understand the hydraulic excavator operating procedures and avoid unnecessary operation errors leading to machine maintenance.
