Recovery Tow Link
Loadquip has developed a Recovery Tow-Link for a range of mining trucks including; Hitachi (EH3500, EH4500 & EH5000), Komatsu (830E, 860E, 930E & 960E) and Caterpillar (789 & 793), with the ability for other models to be developed on request.
The Recovery Tow-Link (RTL) enables the simple and safe towing of a disabled mining truck with another mining truck of sufficient size. In general no modifications are required to either the towing or towed truck, so any suitable truck can be pulled from production for towing duties on short notice. With a total mass of 2.5 tonnes, the RTL can be installed using a lightweight crane in less than 20 minutes. The device is also available as a Recovery Tow-Link Trailer that can be installed without the use of a crane.
The RTL comprises three main elements; the Draw-Bar, the Axle Beam and the Bumper Beam. The Axle Beam attaches to the towing truck and the Bumper Beam attaches to the towed truck. Each of these attaches with the installation of only two pins. The Axle Beam and Bumper Beams attach to the Draw-Bar using a single pin. Operators with mixed fleets can have several different Bumper Beams along with one Axle Beam and Draw-Bar to enable towing of a range of different trucks with a single RTL.
The disabled vehicle requires functioning steering and braking systems. Depending on the requirements of the particular truck these systems can be powered using either a ‘buddy system’ from the towing truck, or via a separate auxiliary power unit which Loadquip can supply. The configuration shown above (Hitachi EH4500 under test) is specifically designed to function around a sound attenuation package on the front of the vehicle, specialised configurations can be supplied as required.
