hydraulic breaker

Excavator thumb attachment A wood grabber, also called a wood clamp, a wood grabber, a material grabber, and a clamp grabber, is a kind of front-end device modified by an excavator or a loader. It is generally divided into a mechanical wood grabber and a rotary wood grabber. The wood grabber installed on the excavator: the mechanical excavator wood grabber is propelled by the excavator bucket cylinder, without additional hydraulic blocks and pipelines; the 360° rotary hydraulic excavator wood grabber needs to add two sets of hydraulic valves on the excavator block and pipeline to control; The wood grabber installed on the loader: the modification of the loader requires modification of the hydraulic pipeline, the modification of the two-way valve to the three-way valve, and the modification of two oil cylinders. The wood grabber is suitable for ports, forest farms, lumber farms, wood products factories, paper factories and other industries for loading, unloading, unloading, arranging, stacking and other operations.

If the hyundai 210 rock breaker is not used for a long time, please keep it as follows: ①Clean up the outside of the breaker; ② After removing the steel brazing from the housing, apply anti-corrosion oil; ③ Before pushing the piston to the nitrogen chamber, the nitrogen in the nitrogen chamber must be sent out; ④When reassembling, the parts on the breaker should be lubricated with lubricating oil before assembling.

Excavator quick coupler, also called quick change joint, quick connector. The excavator quick coupler can quickly install and switch various configuration parts (bucket, ripper, breaker, hydraulic shear, etc.) on the excavator, which can expand the scope of use of the excavator, save time and improve work efficiency. Excavator quick coupler is a structural product, which is composed of main bracket, movable block, hydraulic cylinder, pin shaft and other components.

The excavator ripper is a replaceable working device with the functions of crushing and turning loose. It is divided into ripper for excavator and ripper for bulldozer. The ripper for excavator is also called bucket hook, and the ripper for bulldozer is also called tail hook. An integrally cast ripper tooth with ear holes on the upper part is hinged to the bucket rod and bucket cylinder respectively. The front end of the tooth tip has a hard alloy surfacing tooth cap. When the piston rod of the hydraulic cylinder is extended, push the tooth tip to forcefully insert it. and turn the soil. It is used for excavating cracked rock, breaking frozen soil, and also for excavating asphalt pavement. It is suitable for the crushing and splitting of hard soil, sub-hard stone and weathered stone, so as to facilitate excavation and loading operations with buckets.

According to the function of hydraulic grapple for excavator, it can be divided into: mechanical gripper, 360° rotary hydraulic gripper; According to the number of teeth of hydraulic grapple for excavator：it is divided into two-tooth, five-tooth and seven-tooth grippers. It is widely used in special operations such as sugarcane, wood, stone, material handling and loading and unloading, garbage grabbing, and waste metal processing. According to the shape, the grab can be divided into shell-shaped grab and multi-lobed grab, the former is composed of two complete buckets, and the latter is composed of three or more jaw plates. According to the driving method, it can be divided into two categories: hydraulic grab and mechanical grab. It is especially suitable for foundation pit excavation, deep pit excavation and loading of mud, sand, coal and gravel, and loading and unloading of ships, trains and automobiles.

The excavator grapple is professionally used in the operations of gripping/handling/loading round logs in the fields of cargo port terminals/timber yards, etc. This fixture adopts Q345 high-strength manganese steel plate, and adopts worm gear and worm 360° deceleration rotary mechanism, which has stable rotation and long service life. The clamp adopts a box-type mechanism with strong impact resistance, which effectively protects the clamp.
