New 4-10 ton (50mm/45mm pin) Excavator Mechanical Spring Quick Hitch Coupler

New Excavator Mechanical Quick Hitch Coupling to suit 4-10 Ton machines.

Designed for Caterpillar 416D / 416E / 428 C3 Linkage / 432 C3 Linkage / 438 C3 Linkage etc. but will fit other machines (see below list of machines we have found so far). With some modifications this Hitch could also be setup as an all-45mm pin or all-50mm pin setup (details below).

Want a quick hitch but don't have any spare auxiliary hydraulic lines for a hydraulic hitch? This hitch is identical to a hydraulic hitch setup except you lever the rear pin clasp open and closed with a 16mm diameter rod that compresses the spring.

There is no need to pull either of the pins out of your buckets and try to line up the bucket holes with the hitch holes (like a half hitch requires). Instead you simply hook the hitch into your bucket's front pin just like a full hydraulic hitch, then lever the rear spring open and close the coupling over the bucket's rear pin. The Red pole (pictured) locks the mechanism from moving during use.

The 16.56mm hole that the lever rod goes into is at the end of a round bar poking out the side of the hitch and can be seen in pics# 3 & 5).
Please note! the lever rod is not supplied, but you just need a 16mm-16.5mm pole (preferably solid or thick walled) around 30-50cm long (we used a 300mm extension bar from a 1/2" socket set, works fine).

It is New and well engineered. We have also greased all the nipples so it is ready to work.
