Liebherr LPS 120 portal slewing crane

The LPS 120 from Liebherr is ideal for coaster and feeder ships with a lifting capacity of 42 tonnes and an outreach of 30 metres. The rail-mounted portal crane solution enables the use of the area under the slewing platform, for trucks and conveyor belts, etc. The customised portal also ensures reliable stability in all applications.

Portal

The manual storm anchor is suitable for wind speeds up to 42 m/s.

Four-rope grab control

The synchronisation of the winches is monitored and optimised by the four-rope grab control.

Hydrostatic drive

Closed hydraulic loops are used for all main functions such as lifting, turning and luffing. The crane operator benefits from extremely precise control, the service personnel benefit from a minimum number of components and the operating company benefits from reduced fuel consumption.

Pull cylinder

The pull cylinder over the boom offers many advantages: no collision with swinging load, no buckling of the cylinder and full protection of the piston rod in park position.

4-chord boom

The four struts (lattice design) of the boom provide maximum stability and handle the sideways pull better than alternative boom designs. This results in a longer service life.

Lighting

Operation without a loss of productivity is also possible when it is dark. High-performance LED headlights at the boom and tower provide optimal lighting.

Glass fibre reinforced plastic

The machine housing panels are made from glass fibre reinforced plastic. The advantages include low weight and resistance to rust.

Horizontal load path

During luffing the load always moves along the horizontal load path.

Cooling

The speed of the special Howden coolers is automatically adapted to cooling requirements. As a result, diesel consumption and noise levels are reduced to a minimum and the service life is maximised.

Paintwork

To defy the rough maritime environmental conditions, the standard paintwork comprises a primer coat, an intermediate coat and a top coat.

Litronic crane control

The control system of the mobile harbour crane range, which was developed by Liebherr, focuses on precision, safety and productivity. Obtain a detailed overview here.

Machine housing concept

The single-storey slewing platform houses the drive unit, slewing mechanisms and hoist mechanisms, the control cabinet room and the alternator. All components are easily accessible for maintenance work.

Round tower design

The round tower design minimises damage caused by torsion. Forces are evenly distributed to the steel structure and the slewing ring. As a result, the service life of the crane is increased significantly.

Control cabinet room

All electric and electronic components used satisfy military standards. External environmental conditions have no impact on the functionality. The entire system was developed for the maritime environment with temperatures from -40°C to +80°C.

Slack rope protection

A slack rope protection device is mounted on the winch frame. The winding on the winch is effected evenly, and the hoist rope is always kept taut.

Service network

Like all maritime cranes from Liebherr, our mobile harbour crane can rely on a dense service network worldwide. This ensures short downtimes and a quick response.

Tower cab position

Optimal views for the operator. The forward-mounting position of the tower cab with 70% glass (safety glass) offers the driver a comprehensive visibility range.

Accessibility

Regular servicing maintains the efficiency of the crane. So maintenance work can be carried out quickly, the accessibility of the relevant components is to the fore. This reduces downtimes.
