Shunters up to 2800 tons

Unimog U 423 up to 1000 tons

Efficient and economic use on road and rail

The multi-use and versatility of the ZAGRO road-rail vehicles are based on their efficient operation both on the road and on rails.

Being equipped with specific implements, the Unimog can be used flexibly, e.g. for shunting, repair and maintenance work or for recovery of damaged trains. The vehicle has signal light system, various coupling systems, wagon brake system, safety drive circuit, inductive safety monitoring and radio remote control.

EBO approval

We are familiar with railway regulations and take care of the necessary EBO approvals. Vehicles are built according to current requirements. This ensures the approval as per § 32 Railway Construction and Operations Act (EBO), that allows the operation on public rail infrastructure.

ZAGRO track guiding equipment with system axle

Our patented track guiding system provides perfect running characteristics. The track-guiding wheel is positioned close to the rubber road wheel to guarantee optimum track guidance. Due to our long-standing experience in the fields of designing and manufacturing track guidance systems, the system is safe, efficient and quiet whilst in operation. The ZAGRO track guiding equipment is based on the principle of the single system axle which is suitable for all rail wheel types and sizes: e.g. the larger safe and more robust track guiding wheels of 400 mm diameter or, as an option, the small bogie wheels of 136 mm diameter for narrow curve radiuses.

Modern central control console

The modular design of our new control console utilises CANBus technology. The central LCD control panel with integrated diagnosis system offers operator ease of use and the possibility to use remote maintenance via the worldwide GSM network.

Wagon brake system to move up to 1000 tonnes load

As a shunting vehicle, the Unimog are equipped with a wagon brake system to move and brake up to 1000 tonne trains safely. High-performance compressors, priority filling system, electronic regulating valve with filling speed adjustment, dual chamber air dryer, digital brake and release pressure indicators as well as the automatic operating hours display ensure speedy and safe shunting operations.

Design is our passion

The integrated bumper and ballast plate combine distinctive style with function blending well with the Unimog. Using a sophisticated modular system, which allows various additional equipment such as wagon brake system, track drying device, track sanders, rail wheel chock, radio remote controlsystem, and spare wheel bracket. Retrofitting of any of the above systems is easily possible.

Coupler systems

A wide range of wagon coupling systems is available: mechanical, automatic, with swivelling device, damped or adaptation to a specific customer’s request.

Radio remote control system

As an option, the road-rail vehicle can be equipped with radio remote control system for one-man operation. This system meets all the current relevant safety standards required for class AK4 to AK6. ZAGRO is well known for their ability to provide logical and clear arrangement of components within the radio control system.

Railway equipment

In conformance with the regulations published by the Railway Authorities, we install the correct railway components as requested: isolation of road lighting, inclusion of rail lighting, compressed air rail horn, warning bell, inductive train protection system (INDUSI), dead-man’s handle (SIFA), radio telephony MESA, emergency power-off, earthing device, track circuit bridge-over equipment. We carry out in-house all official railway inspection and acceptance tests (German Railways). We can also provide equipment to meet other rail authority requirements.

ZAGRO E-MAXI XXL in railway operation

TERBERG/ZAGRO Truck up to 2800 tons

The new rail-road tractor TERBERG/ZAGRO Truck RR222/282 is designed for pulling gross combination weights up to 2800 t. The special vehicle is built with standard parts and reliable top quality components. The long-standing experience and bundled knowhow of the two specialised manufacturers TERBERG Benschop B.V. and ZAGRO combines their core strengths in special vehicle technology and road-rail technology.

Proven drive system

The main feature of this tractor is its driving system: two driven axles are designed to meet any requested track gauges and ensure high traction. Since the track gauge of the front steering axle is considerably wider than the drive axles, the tractor can be operated with a very small turning circle of 13,5 meters.

High-capacity wagon brake system

Furthermore, its high-capacity wagon brake system ensures maximum supply in idle condition to save fuel - for the benefit of the operators.

EBO approval

TERBERG/ZAGRO Truck has been approved as per § 32 Railway Construction and Operations Act (EBO) for shunting operation on public rail infrastructure.

Easily accessible for service work

The tilting driver cab and easy to open fiberglass covers allow easy access for maintenance.

Rescue vehicle with box body

The three-axle TERBERG special vehicle will also built into a rescue vehicle. Equipped with a box body, the road/rail vehicle with technical devices and rerailing tools is a compact rescue vehicle. The box body offers sufficient space for a crew cabin for max. five persons and a tool compartment with hydraulic rescue equipment.
