Portal mobile cranes - LPM
The LPM-series combines a space-saving crane installation mounted on a portal with utmost mobility given through conventional rubber tyres. In fact, the design is a mix of the well-established Liebherr mobile harbour crane and the related rail-mounted portal solution. By taking out and combining two essential design elements the LPM was born. A portal crane on wheels is the outcome.

Advantages at a glance
The LPM provides unrestricted mobility as the space-saving portal system is equipped with wheelsets that enable 360-degree mobility.
- Driving in longitudinal, diagonal or transverse direction
- Performance of conventional steering or slewing on the spot
- Electronically controlled
The Liebherr portal mobile crane types have the same technical features as the equivalent Liebherr mobile harbour crane types.
- Same ground pressures under tires and under supporting plates
- Same maximum lifting capacity and load curves
- Same supporting base and load distribution
The unique feature of the new Liebherr Portal Mobile crane is a gantry on rubber tires. Unrestricted mobility enables the crane to be travelled from one quay to another. And especially on quays where space is limited or traffic is high the LPM demonstrates its benefits:
- Precise and individual positioning
- High grade of maneuverability and flexibility
- Good drive-under capability, other vehicles can keep moving unhindered
