LPS 550

With an outreach of 54 metres, the LPS 550 is the ideal portal crane for handling bulk cargoes in the Capesize ship class. For container handling ships of the Post-Panamax class are the optimal working environment for the LPS 550. The rail-mounted portal solution can also manage general cargoes and heavy-duty lifting up to 144 tonnes.

Stage V / Tier 5 final engine

The Liebherr mobile harbour crane is equipped with the latest generation of diesel engines for the exhaust emissions standards of EU stage V or EPA Tier 5 final.

Driver's cab

Noise protection, windshield wiper, air conditioning. The ergonomic and comfortable features of the cab increase the concentration and reduce the fatigue of the crane operator – for consistently high productivity and a high level of safety.

Main supply

The main supply can be effected via low voltage (400 V) or high voltage (1 kV - 20 kV). The cable drum is secured to the portal and independently takes care of the unwinding and winding of the power cable.

Anti-collision protection

Buffers are provided at all 4 corners of the portal as collision protection. Visible limit switches can be installed as additional security.

Safety devices

The safety of people, the infrastructure and the environment takes top priority. Our mobile harbour crane has a number of precautionary measures for increased safety in your port.

Storm protection

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.

Slewing mechanism

The LHM 550 has three slewing mechanisms connected in parallel. The loads for the slewing ring are reduced to a minimum.

Enclosed tower design

The enclosed design of the tower gives the crane operator secure and weather-protected access to the tower cab.

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.

Hoist mechanism

The lifting and lowering movements up to the maximum load capacity are effected steplessly, i.e. without changing gears. The lifting speed is up to 120 metres per minute.

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.

Emergency descent

The emergency descent leads from the cab along the tower to the ground. If the conventional descent is not accessible, the operator can get to safety at any time using the emergency descent.

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.
