Box-shaped measuring system vehicle for mineral oil

With unbeatable manoeuvrability

Employing a distribution vehicle often generates unnecessary costs. This is inevitable in cases where the unloading point is not accessible to a semi-trailer or a truck due to the road and site conditions. WILLIG has a number of economical solutions to this problem:

Technical data


  • Two-axle semi-trailer tanker with rear-steering axle or power-steering axle
    Gross volume 33,000 to 40,000 l with 3 to 5 compartments
  • Single-axle semi-trailer tanker
    Gross volume 25,000 l with 2 to 4 compartments


We can provide an axial hose reel at the front of the end bottom or at the rear in a cabinet. Alternatively, a disc hose reel can be attached to the left in the loading cabinet.

Loading / Discharging

Loading options

  • Top loading via man hole
  • Bottom loading via loading coupling
  • Manual loading via suction

Discharging facilities

  • Metered pump discharging via the measuring system with/without wet hose and/or dry hose
  • Measured gravity discharging via measuring system and dry hose
  • Unmetered discharging with/without pump via the outlet port

Steering system

A power-steering system for the last axle offers the following benefits compared to the conventional rear-steering axle:

  • The steering angle is max. 26° (11° for rear-steering axles).
  • The power-steering axle also works when the vehicle is in reverse. The rear-steering axle is locked.
  • Also available: A control unit so the driver can also manually control the steering axle. This is especially advantageous during shunting and when the complete wheel angle needs to be available immediately from a standing position.

There are two power steering systems to meet specific requirements:

  • hydraulic TRIDEC system
  • electronic VSE system

We are happy to discuss these options with you personally.

Brakes / Air suspension

Braking comfort improved with integrated EBS/ABS brake system and RSS function. Vehicle safety can be increased through selective braking in the case of risk of tipping.

  • The EBS function accelerates reaction and pressure build-up times in the brake cylinders. This reduces the stopping distance by a few metres.
  • Driving stability is assured by the ABS function during the braking process.
  • The RSS function uses selective braking to prevent the tanker from tipping, jack-knifing or skidding.
  • The trailer air suspension can be managed mechanically via an air suspension valve or electronically via an ECAS control box.


The semi-trailer can be fitted with additional safety and technical features:

  • Rear view camera
  • Reflective contour markings
  • Working lights next to the cabinets
  • Reversing lights at the rear
  • EMERGENCY OFF function on each side of the vehicle
  • Automatic braking if cabinet doors open
  • Tyre pressure monitoring system
  • Load-dependent shock absorber control
  • Reverse warning buzzer
  • Reversing area monitoring sensors


Lateral marker lights on the semi-trailer tankers are equipped with LED lights as standard. Benefit: service life of up to 15 years, high light intensity and colour consistency.

  • Hazard signs
  • Hazard labels
  • Cons
  • Binding agent vessel
  • Binding agent
  • Wheel chocks
