Three steps on welding process of excavator steel grab

The excavator is specially used for the grasping and loading of scrap steel, and the hard labor intensity is very large! If your welding process is poor, then the best material material is useless.

No.1:The excavator gripper is one of the excavator working devices, and the hydraulic gripper is one of the excavator working device accessories independently designed, developed and manufactured for the specific work needs of the excavator. Hydraulic gripper is divided into: mechanical gripper and rotary hydraulic gripper; The mechanical gripper can be used without modifying the excavator pipeline and hydraulic system (low-cost type); Rotary hydraulic gripper requires modification of excavator piping and hydraulic system to achieve 360-degree rotation needs (convenient, practical, high cost)

No.2:Excavator gripper:

(1) The mechanical gripper is driven by the excavator bucket cylinder, without adding hydraulic blocks and pipelines;

(2) 360 rotary hydraulic excavator gripper: It is necessary to add two sets of hydraulic valve blocks and pipelines on the excavator to control;
Non-rotating hydraulic excavator gripper: It is necessary to add a set of hydraulic valve block and pipeline on the excavator to control.

No.3:Excavator gripper  Application:

Grab gravel, scrap metal, industrial waste, construction waste, domestic waste workshop grab operations.

The recommended common methods of excavator welding for the excavator steel grab:

There are many welding methods to understand the base material, welding data, welding methods, welding joint types, assembly requirements and other relevant common sense before welding, on the structural parts of the production of welding process parameters and welding sequence, preheating, post-heat and post-welding heat treatment process is more important. Structural parts production welding precautions are still more, you must strictly in accordance with the welding process instructions rules of the process parameters and welding order for welding, especially about the type of butt joint, as well as butt weld and combination weld should be set at both ends of the weld arc and lead plate, pay special attention to is in a rainy day, Or the weather is not good in the general welding, the welding appearance should be kept dry and clean, at the same time, in the construction, the welder should have the welder certificate, welding data weld thickness and flaw detection also have strict requirements…..
