ATLAS Service Manuals, Fault Codes and Wiring Diagrams

Hinrich Weyhausen KG traces its roots back to 1919 when Heinrich Weihausen founded it as a trading company. The foray into agricultural machinery commenced in 1921, marking the beginning of a legacy. A pivotal moment occurred in 1950 with the production of the first hydraulic excavator. In 1986, the company incorporated the Atlas trademark into its name, becoming Atlas Weyhausen GmbH.

The evolution continued in 2002 when the construction equipment line was divested to Terex Corporation. This ushered in the era of cars produced under the Atlas-Terex brand. In 2010, Atlas-Terex found a new home under the umbrella of Atlas Maschinen GmbH, an offshoot of Atlas Weyhausen GmbH.

Today, Atlas Weyhausen stands as a conglomerate comprising ATLAS Weyhausen GmbH and F. Weyhausen AG & Co. KG. Though legally independent entities, they collaborate under a unified brand.

Particularly sought after in the construction industry are the specialized wheeled excavators designed for deep digging. Featuring a unique boom design with a hydraulic telescopic handle and three extension sections, these excavators can delve into wells up to 16.25 meters deep while achieving a discharge height of 2.85 meters, facilitating direct soil transfer into dump trucks. ATLAS wheel excavators, renowned for their versatility, excel in various excavation tasks and material handling operations at industrial facilities, quarries, metal product warehouses, coal, coke, and timber facilities, large container terminals, ports, as well as in landscaping and garbage collection.

The robust construction of these excavators enables them to handle diverse materials with ease, showcasing high maneuverability and mobility. The operator benefits from a comfortable cabin equipped with panoramic windows, reliable sound insulation, an air purification system, and climate control, ensuring optimal working conditions even in challenging environments like dusty quarries and garbage dumps. Ergonomic seats further enhance the operator's comfort during extended working hours. The control system, operated by joysticks, guarantees precision and speed in executing operations. Easy access to key components simplifies machine maintenance, while hydraulic pipelines are robustly protected from mechanical damage. The environmentally friendly working fluid underscores Atlas Weyhausen's commitment to sustainable practices in construction machinery.

A PLEASURE IN OPERATION

Safety, power and fast and comfortable operation set our rail-road

excavator apart, making it amongst the most pleasurable machines

to operate on rail or on site.

Speed – working faster than ever

• The required pressures on the rail guidance wheels are automatically set when the 1404 ZW and

1604 ZW are re-railed. No awkward external adjusting screw to set the contact pressure on the tyres.

• Innovative AWE 4 technology for sensitive, proportional control of all movements irrespective of

load. Travel and work simultaneously. This is the big advantage to you.

• Front and rear wheels can be controlled independently (not with the friction wheel version).

• Simple de- and re-railing ensure high operating comfort for fast, safe and efficient operation.

Tractive force

• Faster on the construction site: the enormous power allows you to use our rail-road excavator

as a “shunting locomotive”. Both models are approved for 40 T un-braked trailer weight and 120 T

braked trailer weight. We can also supply with a wagon brake on request.

Precise operation – optimised for the track

• 4 outrigger stabilisers (with the 1604 chassis) adapt optimally to the rail embankment.

• Customised specification: tailor your excavator precisely to your requirements from the various

superstructures and chassis, for example the superstructure of the 1404 ZW can be mounted on

the chassis of the 1604 ZW for maximum stability with ultra short tailswing.

• Counterweights suitable for the application can be rapidly changed.

• The loading gauge for wagons is met.

A space-saver – great when it gets tight

• Rail-road excavator with ultra short tailswing. Choose between the different counterweight options.

• The 1404 ZW features the shortest tailswing on the market at 1575 mm

making it suitable without restriction for any spacings between rail tracks.

• For narrow gauge tracks, use the 1404 ZW rail-road excavator friction wheel with its up to 1000mm narrow axles.

Reliable – because every minute counts

Our market leadership is based on our well-proven technology –

tried and tested a thousand times over in the most arduous applications.

High-tensile steels, robust electric and electronic components as well as excellent workmanship in all hydraulic components ensure that the

excavator is the reliable heart on any construction site.

THOROUGHLY DESIGNED

Stability

• Low centre of gravity ensures optimum stability in operation.

Assisted by a transverse mounted engine.

Safe on rails

• The outriggers are automatically lifted when the “drive” function is selected.

This avoids damage during rail operation.

• Continuous monitoring of contact pressure. (not friction wheel version)

• The air reservoirs of the wagon brake are located in the superstructure and chassis and

are very well protected.

• De-railing of the bogie by the outriggers is automatically eliminated.

Electronic swing and height limitation

• Computer assisted swing limitation, which proportionally reduces the superstructure speed electronically

when the limit is reached.

• Electronic height limitation eliminates the risk of the excavator boom from coming into contact with obstacles

above such as power cables. The maximum articulating boom height, relative to the point of reference, is taken

into account. The system recognises whether the clamshell or bucket are fitted and adjusts the programmed

operating height accordingly. The motion stops when the programmed limit is reached.

• Swing and height limitation can be comfortably programmed from the operator’s seat.

It is not necessary to get out of the machine.

Emergency de-railing

• Emergency de-railing is permanently available and doubly protected. Firstly by connecting the hydraulics

to the cigarette lighter via an electric cable. Secondly by a fixed emergency hydraulic hand-pump.

• An electric emergency pump is available as an option.

• Emergency lowering of the rail bogie is permanently available.

POWER

Deutz turbo-charged engines provide fast and

powerful motions, a powerful drive train, fast cycle

times and dynamic development in performance.

What you should also know

• Primary and secondary overload protection.

• Suction valves for all operating functions.

• Overload lock valves, precision lowering valves and travel

brake valve.

• Pipe break protection valves for lifting cylinders.

Optionally also on adjusting and articulating cylinders.

• Emergency steering and pressure reservoir for emergency

lowering of the boom system.

• Proportional control of attachments by slider in joystick in the

1604ZW as standard.

Hydraulic system

PRECISION CONTROL • The rail-road excavators are fitted with well-proven load-sensing hydraulics.

Our intelligent AWE 4 hydraulic management system allows simultaneous movements

to be carried out irrespective of load. For more productivity and safe operations.

• The power you need, at the right time.

For fast cycles or high lifting capacity: our load-sensing system attunes the method

of operation of the excavator exactly to your application.

For greater economy – you save fuel and maintenance costs.

FAR-SIGHTEDNESS

The cab with more view

• Two-man cab with excellent all-round vision.

• Optimum lay-out of the controls provides clear view of the attachment.

• Optional: rear view monitoring with camera and display.

Welcome to the “Feel-good” workplace

• The cab is very well isolated from vibrations.

• The sound pressure level is very low thanks to the high quality sound insulation.

• Air conditioning is standard including a defrosting function for fast de-misting and

de-icing of the windscreen.

• The air-cushioned operator’s seat is individually adjustable in all movements.

Backrest, lumbar support, cushion length and angle can all be easily adjusted.

• The narrow steering column gives excellent vision to the attachment and the rail bogie.

Go into (rail) guidance mode

Our CARSY system (Computer assisted rail contact pressure system) electronically

ensures the optimum pressure on the rail is maintained continuously

and automatically.

• The required pressures are automatically set, continuously monitored and adjusted if necessary.

• The front and rear bogie wheels can be independently switched to permit simple de-railing and

positive by-passing of rail points.

• Automatic self-diagnostics of the electronics.

• Available for 1404 ZW and 1604 ZW models.

Operation at the optimum level

• Continuous self-levelling of the rail running gear ensures smooth movement of the rail-road

excavator when travelling on rail.

Optimum grip

• Bogie axle box with optimum oscillation in the axle mountings.

The successful result: safe operation especially on uneven construction site tracks and in cornering.

• With the friction wheel model, traction is provided via a non-slip friction roller.
