If the front beam of the bucket is on the beam, the bucket locking pin should be taken down. 2. If the quick connector cannot be connected, it may be because after the oil circuit is disconnected, the bucket moves up and down for some reason, causing the pipeline oil pressure to be large. At this time, loosen the nut connecting the hard pipe and the hose at the mop tube seat to discharge the high-pressure oil.

With the continuous development of science and technology, in order to reduce the expenditure of human, material and financial resources and reduce the secondary waste of resources, the electric scraper has the characteristics of stable loading, large control range, no sprinkling, high efficiency, continuity and so on, and is widely used. The electric scraper is suitable for mines, railway tunnels, hydraulic culverts and other departments. Here's how to deal with the engine flameout of the electric scraper:

Underground loader manufacturers explain what are the requirements of the scraper before underground work? Often check the tightness of the shaft end fastening screws and tire screws to prevent accidents. During inspection, repair and refueling, the scraper must be stopped, the power must be cut off, and the bucket must be grounded. During inspection, repair and refueling, all parts of the machine must be completely at rest and in a stable state. Due to the limitations of underground

Small scratches and scratches on cars are inevitable. People may get injured and go to the hospital, while cars may get injured and go to the 4S dealership (repair shop). When faced with maintenance, many novice drivers are not familiar with many automotive repair terms and techniques. Many times, a repainting job is said to be about making sheet metal, but you don't even understand what sheet metal is. Today, let me talk to you about the sheet metal and paint spraying of auto repair.

The working principle of a scraper mainly depends on the hydraulic system. A hydraulic pump converts mechanical energy into hydraulic energy and compresses hydraulic oil before sending it into a hydraulic cylinder. The hydraulic cylinder includes a piston and a piston rod. When hydraulic oil enters the hydraulic cylinder, the piston moves in one direction, which makes the hydraulic cylinder have a telescopic function. The bucket is connected by a piston rod and is connected to the body through a support arm. When the piston extends outward, the piston rod will push the bucket forward, thereby picking up objects; On the contrary, when the piston contracts inward, the bucket will tilt towards the body and unload the object.

A shovel loader is a type of soil transportation machinery that uses a shovel to cut soil and load the broken soil into the shovel for transportation. It can complete comprehensive operations such as digging, loading, transporting, unloading, layered filling, and local compaction, and is particularly suitable for leveling sites in railway, road, water conservancy, power and other engineering projects.
