The quick change joint of excavator is one of the accessories of construction machinery. The quick change joint of excavator is one of the accessories of working device of construction machinery which is designed, developed and manufactured independently for the specific working requirements of excavator. Excavator quick change joint is divided into: mechanical quick change joint, and hydraulic quick change joint; Mechanical quick change joint can be used without refitting excavator pipeline and hydraulic system (low cost type); Hydraulic quick change connector requires retrofitting of excavator piping and hydraulic system to meet the requirements of automatic replacement of working device (convenient, practical, high cost type)

Quick change joint application

Quick change joint can quickly install various configuration parts (bucket, crushing hammer, hydraulic shear, etc.) on the excavator, which can expand the scope of use of the excavator, save time and improve efficiency. Divided into: mechanical quick change joint, hydraulic quick change joint. Mechanical wedge or screw positioning, hydraulic oil cylinder on the one-way control valve positioning. The hydraulic type requires a set of backup valves, two hoses, and a solenoid control valve.

Quick change joint characteristics

1. Use high-strength materials; Suitable for all types of 4-45 tonnage.

2. Use the safety device of hydraulic control one-way valve to ensure safety;

3. There is no need to modify the excavator configuration. Also need not remove pin shaft can be replaced, so the installation is fast, can greatly improve the work efficiency!
