Description:

Quick couplers (also called quick hitches) are devices installed at the outer end of the work equipment of various types of construction and earth-moving machines. They facilitate the rapid exchange of working tools or buckets. Quick couplers are most common on hydraulic excavators and compact excavators and on the backhoe equipment of backhoe loaders, but are also installed on telescopic handlers, wheel loaders (loading shovels), skid-steer loaders and the loader equipment of backhoe-loaders. They are also occasionally installed on attachments installed on agricultural tractors. Quick couplers do not normally have a specific function themselves in that they do not carry out handling or digging operations, but when installed on a machine they become a part of the overall system. They are usually mounted on the machine by means of the pins that would otherwise be the mountings for the bucket or attachment. This article concentrates on quick couplers installed on excavators and similar equipment.

Spec. of Quick Hitch:

1. Use material of high strength; Suitable for different machines from 4 to 45 ton.

2. Use security device of hydraulic control valve to ensure the safety.

3. Can change the accessories without disassembling the pin and axle .

4. Thus realize faster installation and much higher efficiency.

Type:

We produce two types of quick coupler: mechanical type and hydraulic type; Mechanical type do not need to modify excavator pipeline and hydraulic system (low-cost); Hydraulic type need to modify excavator pipeline and hydraulic system to achieve the demand of the automatic replacement device (convenient, practical, high cost).

Specifications:

The application of quick coupler/hitch:

Replace excavators various configuration pieces, such as excavator bucket, grapple, ripper, hydraulic shears, broken hammer, etc.
