METDEEM Multi Task Hydraulic Rock Log Grapple for PC CAT Excavator for Wood Stone Grapple Work

METDEEM Multi Task Hydraulic Rock Log Grapple for PC CAT Excavator for Wood Stone Grapple Work

Experts recommend：

METDEEM Hydraulic Rock/Log Grapple is an “intelligent assistant” that turns excavators into material handling devices.
The single-cylinder model is economical and agile, making it easy to handle wood cotton bags.
The double-cylinder model has a huge grip and can firmly grasp huge trees and stubborn rocks.
It can be matched with a 360° imported rotary motor as required, featuring strong power, flexible operation and precise stacking and grasping.
The use of special wear-resistant alloy steel and the reinforced design of the grab blades have extended the service life.
One machine can be used for various materials such as wood, stone, and scrap steel, greatly expanding the applicable working conditions and significantly improving the efficiency of grasping, loading and unloading as well as the return on investment.

Metdeem Hydraulic Rock/Log Grapple–Single cylinder type & Dual cylinder type

1.Single-hydraulic rock/ log grapple

It is driven by a single hydraulic cylinder, featuring a compact structure and high cost-effectiveness. It is particularly suitable for the daily loading, unloading and stacking of materials such as wood, forage and light waste, and is the first choice for forestry, farms and small material yards.
The overall weight is lighter, reducing the requirement for the excavator’s load-bearing capacity. At the same time, it makes the cycle action faster and the fuel consumption lower, making it particularly suitable for occasions that require frequent movement and rapid loading and unloading.
All key components are made of high-strength alloy steel and special alloy wear-resistant teeth to ensure stronger, more stable grasping force and better wear resistance.
The claw flap is designed with a firm grip, allowing for easy handling of various materials such as wood, stone, and waste packaging, achieving multiple functions in one machine.
Thisproducts can be designed to rotate 360 degrees according to the working conditions, making the grasping, loading and unloading operations more flexible and convenient.
2.Dual-cylinder rock/ log grapple
- The dual hydraulic cylinders are symmetrically driven, providing balanced, powerful and extremely stable closing force, which can easily grasp and firmly lock heavy logs, large stones, compacted scrap steel and other “heavyweight players”.
- It is comprehensively reinforced from the grab arm to the main structure, specially designed to withstand extreme impacts and continuous heavy loads. It is a durable fortress in harsh working conditions such as mines, large ports, and heavy waste yards.
- The claw blades are usually longer, and the embedded special alloy anti-slip teeth are thicker and stronger, which can deeply penetrate into the interior of the material, achieving a “bone and flesh connected” grip, effectively preventing heavy materials from slipping during handling and doubling safety.
- It can be equipped with a high-torque rotary motor to achieve 360-degree rotation. The operator can control the material grasping with one click in the cab, easily completing high-difficulty and high-precision stacking and loading operations.

Metdeem Hydraulic Rock Grapple–Guidelines for selection and parameter matching

First, clearly define what kind of materials need to be processed

The single-cylinder type wood grabber is mainly used for wood, cotton bales and lightweight recycled materials. It is agile and convenient.
The double-vat gripper is often used for large logs, huge stones and heavy scrap steel. It has strong and stable grasping force, is safe and efficient.
In mixed working conditions, when it is necessary to switch materials, the appropriate gripper can be selected based on the characteristics of the materials and the complexity of the working conditions.

Second, check the model and tonnage of the excavator that are compatible

For different product models, there are excavators with corresponding tonnages. The appropriate grabber and grabber should be selected based on the model and tonnage of the excavator.
Please carefully check the hydraulic flow rate and rated working pressure of the excavator. They must meet the driving requirements of the wood grabber cylinder and the rotary motor; otherwise, they cannot fully exert their performance.
According to parameters such as the diameter and center distance of the pin shaft and pin hole of the excavator, match the appropriate model of the log grabber.

Third, the core parameters of the product

- The grasping force (T) : determines the grasping force of the grasping tool.
- The opening width (T) : It determines the amount of material that the gripper can grasp in one opening and closing.
- The rotation Angle (N) : It determines the “torque” for the gripper to turn heavy objects and the flexibility of control.
- The self-weight (T) must comply with the safe operating weight of the excavator to ensure safe operation.
