About the Essex Lock-Hitch® Essex Auto Latch®

Essex Lock-Hitch® Auto Latch

It was important that when designing the Essex Auto Latch® that hazards to the operator on implement change over and operator requirements for change over were reduced to provide a safer environment.

The final design results are:

The primary or main system utilizes a wedging action to engage the attachment implement pin which effectively isolates the operational loadings back to the hydraulic cylinder.
The wedging action forces the implement pin against the hitch frame constantly compensating for wear and ensuring that the hitch and implement work together as a tight single entity.

2 to 5 Tonne Class

The safety bar automatically drops in behind the wedge on engagement to prevent the wedge inadvertently retracting.
Should in the unlikely event that the wedge unintentionally retracted the implement will become loose on the hitch but not release indicating to the operator there is a problem.
Two visual flags, one is to indicate engagement of the safety system from the operators’ position. The second is for a secondary person e.g. site inspector to confirm operation prior to commencement of work.
The primary cylinder has a weld on check valve body as an integral part of the cylinder.
The hitch operation mechanism has a guard to avoid foreign objects affecting the hitch operation.
The main design has over 20 years of tried and tested performance and durability.
