Safety issues

The most prominent advantage of Jiangtu fully automatic double locking hydraulic quick hitch coupler is safe.It cancels the hand-inserted safety pin on the basis of the safety of ordinary hydraulic quick hitch coupler. The safety spring and safety hook together form a double safety guarantee against failure.

1. The linkage safety block is installed at the rear hook of the hitch coupler (as attached photo). If the front hook or the piston rod of the cylinder breaks, the safety hook can lock the top pins of the bucket to prevent the bucket and other accessories from falling and causing danger.

2. The safety spring is another important guarantee. When there is a problem such as internal leakage of the oil cylinder, if there is no safety spring, the oil cylinder will retract and drive the safety hook to retract, the hitch coupler and the attachment will be easily separated, and the safety spring will stop the retraction of the oil cylinder and the safety hook to achieve the purpose of protection.

3. In addition, a safety valve is built into the cylinder, to prevent the cylinder from shrinking, forming multiple safety guarantees.

Jiangtu’s after-sales service solemnly promises: six-month replacement and one-year warranty; this after-sales guarantee is beyond the reach of other quick hitch coupler brands in the Chinese market.
