Liebherr-Werk Nenzing in Austria has developed a new 100 tonne capacity class lattice boom crawler crane. The LR 1100 will make its debut at the Bauma exhibition in Germany in mid-April and deliveries will start in the middle of the year.
In a departure from conventional design where steel plate is used the new crane has a tubular structure. It improves performance and gives the crane a different appearance, the manufacturer said. Easy transport and quick set up are features of the new LR 1100. The boom foot and crawler track frames stay on during transport. Instead of having to be dismantled and removed, the catwalks fold down.
An option that increases capacity by around 20 % is a counterweight system that is swung backwards hydraulically. Fixed and luffing jibs are available.
Power is from a 230 kW diesel engine built to meet Stage IV and Tier 4 Final exhaust emission standards. Engines without exhaust after treatment can be specified for markets with other regulations, the manufacturer said.
