Quickhitch
Excavator Arm Quickhitch
General
CAUTION When the quickhitch is installed and its attachment attached, there is a danger of the attachment
hitting the machine. Operate the boom and dipper carefully when the quickhitch and its attachment are
attached.
CAUTION When the quickhitch is attached to the machine, allowance must be made for the weight of the
quickhitch on the rated operating load. The mass of the Quickhitch is stamped on the data plate.
The Excavator Quickhitch, which is attached to the dipper enables the fast removal and installation of the
bucket (and other attachments).
To prevent premature wear, failure and breakage, the Quickhitch assembly must be used with a rockbreaker
for short periods only.
If the machine is to be used for rock breaking for a long period of time, it is recommended that the rockbreaker
is installed directly on the machine.
When using a rockbreaker, it must be curled towards the machine (as a typical digging operation). Do not use
the rockbreaker as a lever as this causes excessive loads on the locking mechanism.
Installation
This operation is easier done by two people, one person to operate the controls and one to line up the pivots.
1. Before the Quickhitch is installed, make sure that the tipping lever locking bolt assembly is attached with
the nut.
2. Put the Quickhitch on solid, level ground. Use the safe and correct lifting equipment to move the Quickhitch.
3. Move the machine so that the dipper arm and Quickhitch are correctly aligned as shown. Refer to Figure 80.
4. Engage the dipper:
4.1. Operate the controls to line up the hole in the dipper arm with the holes in the Quickhitch.
4.2. Install the pivot pin and secure it with the nut and bolt.
5. Engage the tipping link:
5.1. Operate the controls to line up hole in the tipping link with hole in the Quickhitch.
5.2. Install the pivot pin and attach it with the nut and bolt.
