The Yanmar YL4000M Diesel Lighting Tower is a mobile lighting solution designed for construction sites, roadworks, industrial operations and other outdoor work areas requiring powerful illumination. Powered by a Yanmar three-cylinder diesel engine, it features four 1,000W metal-halide lamps mounted on a manually operated, 9-metre telescopic mast.
With a 360° rotating mast, a 114-litre fuel tank and an integrated trailer-mounted design, the YL4000M supports extended site lighting and convenient relocation between work areas.
The Yanmar YL4000M combines high-output lighting, diesel power generation and mobile deployment in one integrated unit. Its four metal-halide lamps provide broad-area illumination, while the telescopic mast raises the lights to a maximum height of 9 metres to illuminate large work zones.
A Yanmar 3TNM72-GHFCL diesel engine powers the unit, supported by a radiator cooling system and a brushless alternator. The lighting tower also provides auxiliary electrical power when the lights are switched off, allowing additional compatible electrical equipment to be powered within the unit’s rated capacity.
The trailer-mounted chassis includes stabilizers, forklift pockets and a transport arrangement for moving the tower between suitable work locations. A digital Yanmar M7 controller, emergency stop button and service-access panels support operation, safety and routine maintenance.

Key Features and Benefits
High-output site illumination
Four 1,000W metal-halide lamps provide powerful illumination for large outdoor work areas and night-time operations.
9-metre telescopic mast
The manually operated mast raises the lamps to an elevated position to improve light distribution across work zones.
360° mast rotation
The rotating mast allows lighting direction to be adjusted according to site layout and operational requirements.
Yanmar diesel engine
The three-cylinder, naturally aspirated engine delivers power for the lighting system and integrated auxiliary generation.
Extended operating time
The 114-litre fuel tank supports operation for up to 65 hours under the specified operating conditions. Actual runtime varies with load and operating conditions.
Auxiliary electrical power
The unit provides a rated auxiliary output of 6.0 kVA / 6.0 kW with the lights switched off, subject to electrical compatibility and rated limits.
Digital control panel
The Yanmar M7 digital controller provides the tower’s control interface.
Mobility and site positioning
The trailer-mounted chassis, drawbar, tyres and transport equipment support relocation between suitable work sites.
Stabilizers and emergency stop
Stabilizers support setup at the operating location, while the emergency stop button provides an accessible shutdown control.
Practical maintenance access
Service-access doors and an accessible control panel help simplify routine inspection and maintenance.
The Yanmar YL4000M is suitable for work environments where portable, elevated lighting is required, including:
Site suitability depends on the required illumination level, ground conditions, positioning space, noise restrictions and electrical requirements.
The YL4000M is a mobile diesel-powered lighting tower equipped with four 1,000W metal-halide lamps, a 9-metre telescopic mast and an integrated auxiliary power system.
It has four 1,000W metal-halide lamps.
The mast extends to a maximum height of 9 metres and can rotate through 360°.
The specified maximum operating time is up to 65 hours. Actual runtime depends on operating conditions and load.
Yes. The unit has a rated auxiliary output of 6.0 kVA / 6.0 kW when the lights are switched off. Connected equipment must be compatible with the available voltage, frequency and outlet ratings.
It uses the Yanmar 3TNM72-GHFCL, a three-cylinder, naturally aspirated diesel engine with radiator cooling.
Its mobile design, elevated lighting mast and broad-area illumination make it suitable for many construction, infrastructure and roadwork applications, subject to site and lighting requirements.
