The electrohydraulic grab is a hydraulic system with a motor,hydraulic pump etc,and is opened and closed by an external power supply. The grab controls the opening and closing of the grab by means of a positive reversal of the motor or a hydraulic reversing valve. Electro-hydraulic oeange peel grab is an effective tool for loading and unloading stones, scrap, garbage, etc. in a variety of harsh environments.The main components of the valve system, seals, valve blocks and other components of the hydraulic system are European and American brands.The pressure change of the system can effectively control the output of the pump. When the maximum pressure is reached, the flow rate of the pump is extremely low, thereby greatly reducing the overflow, reducing the energy consumption, reducing the oil temperature, and using the continuous work for a long time, which greatly improves the production efficiency. Grab structure is simple, easy to operate, can work in a variety of harsh environments. The unique sacral curve is particularly suitable for the loading and unloading of various types of bulk cargo. The upper part of the grab has a cable interface to facilitate the connection with the crane.
The wireless remote control grab is a kind of bulk grab that can be applied to the single cable grab in the air. It is usually used with a single-hook crane, which solves the difficulty of traditional single cable grabs with low working efficiency and large operation intensity. For single-hook type cranes and ship cranes, its work is reliable and easy to operate. The grapple comes with a closed hydraulic system. The wireless remote control device is used to realize the opening and closing of the grab. It not only has the characteristics of simple structure and reliable use of the rope grab, but also has the characteristics of high production efficiency of the power grab. It is widely used in ships, ports, stations, factories, mines and other industries. It is an ideal tool for handling bulk cargoes such as coal, mineral powder, bulk chemical fertilizers, and yellow sand. The wireless remote control grab can work under harsh environment such as high temperature, cold, dust, rain, etc. and its performance is not affected. The remote control distance can reach more than 100 meters. The grab uses high-performance battery. After each charge, the grab can be Continuous operation for more than 100 hours. Connection to the crane: The balancer of the grab can be used directly on the hook of the crane.
The four-rope clamshell grab is an effective tool for loading and unloading bulk cargoes such as yellow sand, coal, mineral powder, cement, and bulk chemical fertilizers under various harsh environments. The grab structure is simple, the failure rate is low, the operation is convenient, and the opening and closing motion can be accurately completed under various conditions. Grab adopts three-dimensional virtual design and uses ANSYS for strength verification and analysis. The weight distribution is more reasonable and the service life is longer. After years of accumulation, our company has formed a series of hundreds of types of grabs ranging from 1t to 100t, which is the first in the same industry in China. Grabs are suitable for loading and unloading all kinds of bulk cargo with double-reel cranes and can be applied to cranes with various pulley arrangements. There are often six types according to the arrangement of the pulleys and the connection to the crane.
Large dredging grab is an effective tool for dredging silt, hard mud, iron plate sand, blasting reef and even sunken ship. This kind of grab is efficient, durable, easy to maintain, easy to operate, and working well under harsh conditions.
The pulleys in the grab with many seal, which ensures that the grab will not permeate the water and sediment in seawater. After years of research, our company has developed a series of products from 6t to 200t. This type of grab is suitable for single ,two and four rope crane.
The diesel engine drives hydraulic grabs, including rings, shackles, housings, underbearing beams, bucket bodies, hydraulic devices, and radio remote control devices. The hydraulic devices are equipped with hydraulic pumps, oil cylinders, and control valve block systems. The hydraulic pumps are connected to the diesel engine connected thereto. The power is provided and the cylinder is driven through the solenoid valve. Both ends of the connecting rod are respectively connected to the inner edges of the two buckets through the pin shaft to limit and protect the grab when it is opened and closed. The grab can be remotely operated. Grab grabs with remote control or without any power supply, drive the cylinder to open and close the grab, pick and place the cargo, adapt to the harsh working environment, work under high frequency conditions, and extend the grab The working life of the company increases the efficiency of the company and overcomes production safety hazards, and is easy to operate.
This equipment is mainly used for the unloading and loading of bulk cargoes. The bulk cargo is grabbed by a portal grab crane, and the grabbing materials are run to the loading and unloading by the relevant operation mechanism of the gate grab crane. Above the system, the grab is opened by the PLC control system of the portal crane and the bulk cargo is unloaded into the unloading funnel of the loading and unloading system; an electrohydraulic push rod control device is located on the discharge opening of the unloading funnel. It is used to control the flow of material, so that it is safe and effective when loading the vehicle, which greatly improves work efficiency.
�?� The hopper of this equipment is divided into two layers, because the lower hopper of the upper hopper is relatively large, the hopper is not easy to raise dust, the suction port of the dust collector is arranged in the middle of the two layers, and the upper and lower material ports are sealed and dusted with a pulse bag filter.
�?� ï¿½?� ï¿½?� The funnel designed by our company is mainly used for loading and unloading coal slag, cement powder and iron powder, and can be designed according to the requirements of customers. The dedusting device, electro-hydraulic door device and vibration feeding device can be installed on the funnel, which greatly improves the Handling efficiency. This equipment includes bagging machine, main support steel frame, gravity feed funnel, power distribution box, discharge chute, bag holder, pneumatic system and some optional devices such as dust collector, empty Presses, etc. Among them, the DCS bagging machine consists of feeders, weights, etc. This device is used for weighing and bagging various small particle materials such as grain, dried cassava, fertilizer, PVC powder, small pellet feed, etc. Small particles of ore, bauxite and so on.
