Our premium product: The direct dispenser for mineral oil

Our star at the petrol station

Semi-trailer tankers from Willig are perfectly tailored to the demanding requirements facing petrol station supply. They are ideal for transporting 1203 gasoline and 1202 diesel/heating oil. The trailer can be fitted with or without a dipstick measuring system. Weight-optimised trailers considerably reduce the empty weight and thus reduce heating consumption and tyre wear during transportation.

Technical data

Tank

A fully cylindrical design provides optimum stability against dynamic forces. The semi-trailer tanker offers a stable drive thanks to its low centre of gravity and favourable surge behaviour. As direct dispensers, we recommend the following tank sizes for the transportation of 1203 petrol and 1202 diesel/heating oil:

  • Gross volumes:
    43,000 l with 4 to 5 compartments

Fittings

Cabinet
The lightest version is a divided cabinet featuring the Willig swivel door. A continuous control cabinet with prarllelogram or swivel doors is also available.

Auxiliary cabinet
The auxiliary cabinet is individually manufactured to the maximum possible size. Depending on requirements, it provides space for cloths, tools, gloves and spare parts. A printer or hose reel can also be integrated.

Hose storage tubes
Various lengths and sizes of hose storage tubes are available: 2”, 3” and 4”. Collection of drips within the pipes can be emptied using the drain valve at the rear.

Loading / Discharging

Loading cabinet
As shown here, if required, the bottom loading and discharging system can be placed on the left side of the vehicle using loading/discharging couplings.

Discharging cabinet
All components are securely installed in the user-friendly control cabinet. Lateral hose holders make it possible to carry additional hoses.

Controller cabinet
An aluminium box for the controller makes it possible to operate without having to open the doors on the control cabinet. The controller is positioned in a protected space next to the control cabinet.

Electronics

The following systems are available as extras:

  • Triple overfill protection system with cross over prevention sensor cable
  • Cross over prevention for the correct allocation of the product
  • Loading hose protection system for the proper connection of hoses
  • Monitoring of the cabinet doors
  • Sealed Parcel Delivery System (SPD)
  • GPS integration
  • GSM data transfer system

Measuring systems

Portable turbine wheel meter
The turbine wheel meter DN 80 is attached between the discharging unit on the semi-trailer tanker and the empty hose. It can be used in hazardous areas but doesn’t come with an official approval. Flow rate: min. 250 l/min, max. 2,000 l/min.

Electronic dipstick measuring system
The calibrated measurement of the fill level is achieved using bearing tubes in the compartments.

System benefits:

  • Shorter discharging times thanks to the faster flow
  • Higher usage load compared to a measuring system vehicle
  • Volume control during loading thanks to bearings on the vehicle.
  • Temperature compensation
  • Guaranteed purity (cross over prevention)
  • Monitoring of empty compartment
  • Tilt monitoring

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.

Safety

The semi-trailer tanker can be fitted with extra safety equipment upon request:

  • 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
  • Emergency brake light (flashing brake lights in the event of emergency braking)
  • Tyre pressure monitoring system
  • Load-dependent shock absorber control
  • Reverse warning buzzer
  • Reversing area monitoring sensors

Lighting

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.

ADR features

Each semi-trailer tanker is supplied with full ADR features for road-worthiness. Depending on the type of vehicle, you receive:

  • Hazard signs
  • Hazard labels
  • Cons
  • Binding agent vessel
  • Binding agent
  • Wheel chocks
  • Shovel and brush
  • Protective equipment
  • Fire extinguisher etc.
