When we set the design criteria with the design team the critial design features we were after were the following:

• Compact and light
• Internal cylinders
• Tilts 45 degrees each way
• Ease of hosing
• Durable
• Cost effective
• Rebuildable

The design which was eventually chosen is in many ways very simple, which really is the beauty of it.

At the centre of the design is a single double-acting cylinder, which provides the tilting action 45 degs each way. The cylinder is sized and mounted in such a way so that when the power is on the rod side of the cylinder it has the same force as any of the equivalent on the market. When tilting the opposite way it has around 180% more tilting force. One cylinder instead of two has meant that weight, maintenance and hose costs have been cut down. As far as we are aware it is the most compact and the lightest.

Rotoloc Mechanism
Like the Standard Rotoloc hitches the Tilt hitch uses the well-proven “Rotoloc lock mechanism. How it works is that the rotor, which rotates in the hitch body, has an inner bore which is eccentric to the outer diameter. As the rotor turns into the lock position the distance between the half bush and the rotor is ever increasing. The rotor turns until one bucket pin is fully engaged in the half bush and the other is locked in the rotor.

With this unique system one of the advantages is that when digging all reverse forces are applied to the rotor and absorbed directly by the hitch, in a radial fashion around the rotor. The rotor-activating cylinder feels none of these forces.
Another major advantage is that because the design holds the implement pins tight during all operations, pin wear is virtually nil.

Safety is built into the design.
Pilot pressure is used to continually turn the rotor round the pin. This is important as if you lose pilot pressure due to a hose failure or the like the machine instantly becomes non- operable.

As the reverse digging forces tend to tighten the rotor's grip on the bucket pin, full mains pressure is needed to break the rotors grip
Also as an added level of safety, a valve is fitted to the rotor cylinder that won’t let the rotor loosen unless mains pressure is applied.

Features

• Hitch can be locked in the straight position with lock bolts provided.
• The trunions have replaceable hardened bush pressed on to stop wear.
• The trunion cylinder bushes are cheap and easy to replace.
• Main pivot bushes are spherical plain bearings, which are sealed. Because the movement is within the bearing and not bearing to bush they are extremely durable.
• Gooseneck of hitch is fully machined giving excellent support to pin.
• Main pins are threaded to help extraction.
• Grease points are protected
  
• Hitch allows bucket to be turned and used as face shovel.
• The hitch has been through stress analysis (FEA) to ensure that it will take the stress loading yet not heavier than need be.
