LPS 420

The key data of the LPS 420 include a lifting capacity up to 124 tonnes and a maximum outreach of 48 metres. Installed on an individual portal solution from Liebherr, the Liebherr crane ensures flexibility in the port. It is suitable for the efficient handling of bulk and general cargoes and containers.

Features

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.

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

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.

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.

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

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.

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

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

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.

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.

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.

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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