Features

Portal

Portal

The design of the portal is customised. This includes: rail spacing, portal height, wheel loads and ladder to the slewing platform.

Stage IV / Tier 4 final engine

Stage IV / Tier 4 final engine

The Liebherr mobile harbour crane is equipped with the latest generation of diesel engines for the exhaust emissions standards of EU stage IV or EPA Tier 4 final.

Driver's cab

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

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

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

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

Storm protection

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

Four-rope grab control

Four-rope grab control

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

Hydrostatic drive

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

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

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

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

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

Horizontal load path

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

Cooling

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

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

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

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

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

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

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

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

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

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.

Radio remote control

Radio remote control

The radio remote control combines user-friendliness and functionality. All crane movements are easy to control, also from outside the cab.

Central lubrication

Central lubrication

The central lubrication system requires less maintenance. Relevant crane parts are automatically and independently lubricated by electric pumps.

Electric drive

Electric drive

The entire range of LHM models can be equipped with an electric main drive – for more environmental friendliness. A high-voltage or low-voltage connection is required for this drive.

Economy software

Economy software

Whether idling or under full load, EcoMode reduces the engine speed to the required minimum. This reduces emissions, material wear and operating costs.

Lower cabin

Lower cabin

Mounted on the slewing platform, the lower cabin is used for moving the crane in the port. Its high position substantially increases the visibility of the driver and greatly reduces risked associated with poor visibility.

Noise protection

Noise protection

There is a special protection package for use in areas with strict noise level requirements. With the reinforced soundproofing of the machine room, further noise reduction of up to 50 percent is achieved.

Fleet management
