Introduction

Quickhitches are used on machines to allow the rapid

change of buckets, shovels and other attachments

on the machine.

Quickhitches 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 machine system.

They are usually mounted on the machine by means

of pins that would otherwise be the mountings for the

shovel or attachment.
