Product Description

Product Description

 

operating principle

It is usually driven by a hydraulic cylinder, locked by a hydraulic control check valve, and disengaged and clamped by an electromagnetic directional valve. 4. When it is necessary to replace the working device, the driver operates the pilot valve in the cab to control the expansion and contraction of the hydraulic cylinder, so that the movable grapple or clamp block loosens or clamps the connecting shaft of the working device. At the same time, mechanical locking devices such as mechanical locks or safety pins are provided to form a double lock with the hydraulic lock, further ensuring that the working device will not accidentally fall off during the operation process.

physical design

Main components: Generally composed of connector housing, fixed grab hook, movable grab hook, mechanical cylinder and related hydraulic components.

Material selection: To withstand the huge impact and load during the operation of an excavator, key components are usually made of high-strength alloy steel. For example, components such as connector housings and grabs may be made of quenched and tempered 45# steel to improve their strength and wear resistance.

application scenarios

Widely used in fields such as construction engineering, road construction, mining, and municipal engineering. In these scenarios where the excavator's working device needs to be frequently replaced, the double-lock quick connection can fully exert its advantages, improve construction efficiency, and reduce labor intensity.

 

Our Advantages

 

High safety: The double-lock design effectively reduces the risk of the working device falling off during operation. Even if the hydraulic system malfunctions, the mechanical lock can also play a certain fixing role to ensure the safety of operators and surrounding personnel.

Fast and efficient connection: Compared with traditional connection methods, it greatly shortens the time for replacing work devices and improves the working efficiency of excavators. Generally, it only takes about 20 seconds to connect or replace a work device.

Strong applicability: Applicable to various models of excavators with a tonnage of 3 to 80. It can be quickly connected to different types of working devices such as buckets, breaking hammers, rippers, and log grapples.
