Liebherr LTM 1040-2.1

The Liebherr LTM 1040-2.1 was unveiled in 2006 alongside the LTM 1160-5.1, representing a significant advancement in the two-axle all-terrain crane segment. With a maximum lifting capacity of 40 tonnes, the LTM 1040-2.1 was marketed as the most powerful two-axle crane on the market at the time of its launch. It was designed to deliver robust lifting capability while maintaining compactness and high mobility—making it ideal for tight job sites and urban areas.

The crane is equipped with a 35-metre, four-section telescopic boom, which is 5 metres longer than that of its predecessor, the LTM 1030-2.1. The increase in boom length contributes to an average load capacity improvement of around 8%, and up to 25% for steep boom angles, enhancing operational efficiency across a wide range of lifting tasks.

Boom extension and retraction are handled by a hydro-mechanical system, comprising a single-stage, double-acting hydraulic ram and a double rope-and-pulley mechanism. This system allows for stepless extension of the boom, even with a load suspended—a feature that significantly boosts both safety and productivity.

An optional 9.5-metre folding fly jib can be added to the main boom, extending the maximum hook height up to 45 metres and maximum working radius to 39 metres. The jib can be mounted at various working angles—0°, 20°, 40°, and 60°—offering operational flexibility for different site requirements.

The crane is equipped with Liebherr’s LICCON control system, which includes a comprehensive diagnostics feature and enables up to four crane movements to be performed simultaneously. The control system is paired with load-sensing hydraulics, which ensures optimal response and precise operation even under demanding conditions.

Under the hood, the crane is powered by a turbocharged inline six-cylinder diesel engine producing 205 kW (278 HP) at 2,200 rpm. This engine complies with EU Stage III / EPA CARB Tier 3 emission standards. Power is delivered to both axles via an automatic powershift transmission with integrated transfer box, providing both all-wheel drive and all-wheel steering. The crane is capable of diagonal travel, thanks to the ability of the axles to steer in the same direction. Safety features include ABS and wheel slip control, ensuring secure driving performance.

In March 2015, Liebherr introduced a facelifted version of the LTM 1040-2.1. This version includes:

• A redesigned front bumper in line with the styling of newer Liebherr models.
• The latest operator cab offering improved comfort, ergonomics, and visibility.
• Disc brakes as standard, providing better braking performance and reduced maintenance.
• Updated Stage IV final Mercedes-Benz engine for improved emissions compliance.
• A Telma retarder braking system for enhanced control during travel.

Integration of Liebherr’s VarioBase® system, which allows the outriggers to be extended independently, improving lifting capacity and safety for asymmetric setups.

The compact and lightweight build of the LTM 1040-2.1, combined with its powerful lifting performance and ease of transport, has made it a go-to machine for crane rental companies and construction contractors worldwide. Its capability to travel with all equipment on board and still remain within road limits is a crucial advantage for operations that require rapid deployment and minimal setup time.

In the UK, Emerson Crane Hire became one of the first to take delivery of the newly updated LTM 1040-2.1, further endorsing its position as a trusted machine in the mid-range all-terrain crane category.
