Truck/Bus- Magnum

Supplier: Autowash

The Magnum gantry system generally requires a wash bay length of minimum 34 metres.



Characteristics of System

The Magnum gantry system generally requires a wash bay length of minimum 34 metres. The vehicle remains stationary whilst the gantry travels the length of the vehicle.

The machine is capable of delivering a full b-double wash program in approximately 12 minutes. The program cycles are as follows:

  • Detergent pass – applies either a light acidic or light alkaline based detergent (dependent on washing application)
  • High pressure, high volume Jet stream pass, concentrating on the prime mover and wheel areas.
  • Brush pass – which generally commences on the trailer (we advice that brushes should be kept out of contact of most prime movers)
  • Rinse pass – fresh water rinse pass to ensure spot free dry

Prime Mover Wash

Zero degree high pressure, high volume nozzles provides an effective prime mover wash and also effectively wash the sill area and tyres. The nozzles move multidirectional motion (laterally and up and down) which can be programmed to ensure difficult areas of the truck are cleaned.

The wash cylinders are electronically controlled (MPC) so that the applied brush pressure is regulated for a contour-following, gentle and effective wash.

Washing B-Doubles is no issues. A safety function prevents the wash cylinders from contacting the drawbar and coupler.

Frequency controlled geared motor drives guarantee jolt-free and therefore low-wear unit operation. Minimum wash times can be achieved with speeds variable from 6 – 18 m/min.

Electronic Control

Each programmed washing sequence is electronically controlled by the Stored Programmable Control to suit the program or variety of programs selected including application and dosage rate of cleaning solutions. Actual water and brush pressure during wash programs is separately controlled for each wash station.

All operating conditions are electronically monitored and adjusted by the SPC during each wash cycle. All wash cycles are selected at the “user friendly” control panel.

The truck driver simply parks the vehicle in the wash bay and selects the appropriate wash program for his/her vehicle (e.g. b-double, tanker etc). The Magnum can also be configured to produce a ‘speedy’ drive through program. The control panel has been designed for easy use.
