TRYBERG TWM-180LGP PAYWELDER

TWM-180LGP is a wetland crawler paywelder specifically engineered for pipeline construction in swamp and soft terrain conditions. Equipped with a reliable power system and a low-ground-pressure (LGP) chassis, it delivers excellent mobility, strong traction, and stable power output, making it an ideal solution for demanding pipeline construction environments.

Key Benefits & Field Performance

• Outstanding mobility in challenging terrain – The TWM-180LGP offers excellent off-road capability for wetland and soft terrain environments.

• High productivity – Supports up to four welding inverters simultaneously (Lincoln Electric DC‑400, Invertec V‑350pro, Invertec STT II, or equivalents). The system is resistant to overheating and does not require work breaks.

• Fuel flexibility – Cummins 6BTA5.9‑C180 engine (Euro‑2 emission standard) allows use of lower‑grade fuels.

• Heavy‑duty crane – High lifting moment and large working radius, designed for operation from –40 °C to +40 °C.

• Reliable components – Built with components from leading global manufacturers: CUMMINS, STAMFORD, HIAB, UNIC, DELIXI, DOOSAN, and others.

• Simple operation – Intuitive controls and straightforward maintenance.

• Proven in extreme climates – TRYBERG TWM‑180LGP paywelders are field‑tested in arctic conditions (down to –40 °C), desert environments (up to +40 °C), and high‑altitude terrain (up to 3000 m). They have demonstrated reliable performance across the Russian Federation, Central Asia, and the Middle East.

• Welding stability – Self-propelled TWM-180LGP provides stable welding parameters even when four welders operate simultaneously.

Main Features

The TWM-180LGP Paywelder is a modern pipeline welding machine designed for wetland and soft terrain construction. Featuring a low-ground-pressure (LGP) chassis, it delivers excellent mobility and stability in challenging environments, and can operate at altitudes of up to 3,000 meters.

The machine is built as a universal tracked module and includes:

• A single power unit for both propulsion and electric power generation — a Cummins engine;

• A hydraulic crane unit (FURUKAWA UNIC, Japan) with a high lifting moment, suitable for handling heavy welding tents;

• A STAMFORD generator unit that supplies power to up to four welding stations for manual or semi-automatic welding, compatible with self-shielded welding wire systems such as Lincoln Electric’s Idealarc DC-400 combined with the LN-23P wire feeder.

Tryberg welding tractors are also designed to carry auxiliary equipment, such as welding tents, pipe alignment frames, induction heaters, and more.

Operating Conditions

• Outstanding mobility in challenging terrain provided by 800 mm wide triangular swamp tracks

• Operating altitude: up to 3000 m above sea level

• Ambient temperature range: from –40°C to +40°C (–40°F to +104°F)

Undercarriage (LGP Version)

The TWM-180LGP is specifically designed for swampy and low-bearing soils. It is equipped with 800 mm triangular swamp tracks, which provide low ground pressure and high traction.

Engine

Both models are powered by a Cummins 6BTA5.9-C180 engine (180 hp), licensed by Cummins (USA) and covered under the Cummins Worldwide Guarantee Program.

Using a single power plant for both movement and power generation reduces the range of consumables compared to twin-engine configurations and cuts technical service costs in half.

Key advantages of the engine:

• Fuel consumption: 206 g/kWh — 22% more economical than competing engines;

• Service life: at least 20,000 operating hours before the first overhaul;

• Optional Eberspächer autonomous pre-heater for reliable starting at temperatures as low as –40°C.

Operator Cabin

The cab is sealed and comfortable, equipped with:

• Air heater and fan (air conditioner available as an option);

• Windshield that slides up fully and can be used as an emergency exit;

• Anti-vibration seat for operator comfort;

• Optional autonomous cabin air heater for operation in extremely low temperatures.

Electrical System

The TWM-180LGP is equipped with a STAMFORD UC alternator (Cummins Generator Technologies, UK), designed to supply power to up to four welding inverters, such as the Lincoln Electric DC-400 or equivalent models.

The electrical cabinet includes DELIXI DZ47 63A series circuit breakers (400 V AC, 4500 A breaking capacity), providing protection against overloads and short circuits.

• Welding tents

• Internal line‑up clamps

• Bevelers

• Pipe joint heaters

• Other field equipment

Welding System Configuration

The compartment layout of the TWM-180LGP allows installation of up to four welding inverters, such as the Lincoln Electric Idealarc DC‑400 or equivalent models, in combination with mobile self‑shielded wire feeders (e.g., LN‑23P). This configuration supports semi‑automatic welding with self‑shielded wire for trunk pipeline construction.

Note: Welders are not included in the standard configuration and can be installed upon customer request.
