Atlas Copco introduces four 1,000 W HID light tower with vertical hydraulic mast

Atlas Copco has launched the newest addition to its range of light towers. The QLT H50 uses four 1,000 W metal halide lamps to deliver reliable lighting even in extreme conditions, improving safety at night. “Its robust construction and components ensure optimal safety, operation and manoeuvrability,” the company says. The vertical hydraulic mast has a maximum height of 9 m and 340° rotation. Four stabilisers ensure safety and support.

Whereas other light towers only have an on/off button, the QLT H50 has an integrated control panel. The Lc 1003 controller is built into the canopy to avoid contact with hot or moving parts during operation. It sequences the start-up of each lamp to minimise the typical risk of alternator and ballast failures. Pulse and Pause Ballast technology is used to prevent lamp filament damage through ballast pulse repetition. 

The unit has been developed to be robust and versatile for any mining worksite.

Key elements of the light tower, including pulleys, steel cables, cable clamps and lifting beam, have been certified as EU safety yield factor ‘5’. This means these elements are five times ‘over-specified’ according to EU safety norms. The vertical hydraulic mast is designed to remain stable in winds of up to 80 km/h, for additional safety in extreme weather.

The heavy-duty canopy is made of galvanised steel to prevent rust and corrosion. The polyester powder paint coating has a resistance of 720 hours in salt spray testing.

Service costs during the unit’s lifecycle are minimised by the long service intervals. Large hatches reduce maintenance times by facilitating access to all key components of the light tower, including the engine, alternator, hydraulic system and electrical system. The oil and water drains are also easily accessible.

“Our customers asked for predictable light: compact, powerful and versatile. With the QLT H50, we tick all those boxes,” says Sergio Salvador, Product Marketing Manager Light Towers, Atlas Copco Portable Energy. “The QLT H50 is easy to move, safe to operate and efficient in its use. Safety is built into every component, from the vertical hydraulic mast to the controller that sequences the start-up of each lamp. We’re confident our customers are going to love this light tower.”
