Clamp Type Wood Grapple

clamp-type wood grapple is one of the important working devices of an excavator. Here is a detailed introduction to it:

- Structural composition: It is mainly composed of grapple claws, oil cylinders, connecting frames, etc. The grapple claws are usually made of high-strength wear-resistant steel. The oil cylinders are used to control the opening and closing of the grapple claws, and the connecting frame connects it to the arm of the excavator.

- Working principle: It is powered by the hydraulic system of the excavator, which drives the oil cylinders to expand and contract to realize the opening and closing actions of the grapple claws, thereby grabbing and moving objects.

- Classification: According to the rotation function, it can be divided into mechanical wood grapples and rotary wood grapples. The mechanical type is pushed by the bucket cylinder and can only swing back and forth, while the rotary type can rotate 360 degrees, making the operation more flexible. According to the number of oil cylinders, it can be divided into single-cylinder wood grapples and double-cylinder wood grapples. Single-cylinder wood grapples are light in weight and flexible, but have a light grabbing weight and poor structural strength. Double-cylinder wood grapples have strong holding force and high structural strength, but are heavier.

- Features: It has strong versatility and can be adapted to different models

In addition, the clamp-type wood grapple can be equipped with cutting components such as saw blades and motors to become a clamp-type wood grapple saw, which is used for rough processing such as log cutting.
