SENNEBoGEN LAuNCHES NEW TELECRAWLER
German manufacturer Sennebogen has launched the 80-tonne capacity 683 E. telescopic crawler crane. The mid-sized machine fits into the gap between the existing 673 E and the 6103 E and is the ninth model in the series. Sennebogen says the 683 E, with its
heavy-duty boom and powerful travel and winch motors, has been built for a wide range of applications including pick-and- carry work. It can still lift on inclines of up to four degrees. The 683 E is powered by a 186 kW
Cummins engine with Stage V exhaust gas treatment. The main and auxiliary winches are driven by a high-pressure piston engine which provides a tractive force of 72 kN each and speeds of up to 120 m/min.
The individually configurable equipment can be supplemented
by a range of options including a programmable working range limiter plus safety and low-temperature packages. This, Sennebogen believes, will particularly appeal to users in specialised civil engineering and hydraulic engineering sectors. The crane has a four-section full
power main boom with a length of 42 m. Multicylinder technology means the maintenance-free boom provides variable telescoping with force-locking. The crane’s reach can be further extended to up to 57 m with an optional double folding jib (that can be angled). The 683 E’s undercarriage has a
maximum track width of 4.2 m. This can be reduced symmetrically or asymmetrically to 2.68 m with the load charts being automatically adapted to the respective track width.
Using a radio remote control the 6103 E can unload itself from a truck and is completely self-assembling. With crawler tracks attached it has a transport width of only 3.5 m. After disassembly of the crawler, the transport weight is reduced by almost 20 t and the transport width contracts to 3.0 m.
BATTERY-poWERED LIEBHERR CRAWLER FoR SIMS
Tampa, Florida, USA-based crane rental and rigging service Sims Crane & Equipment has expanded its fleet with an LR 1250.1 Unplugged crawler crane. The battery-powered LR 1250.1 Unplugged is the first model of Liebherr’s Unplugged series to be sold on the US East Coast. The crawler crane with electric drive
system offers the same performance as the conventional version just with zero emissions.
Jackson Sims, the owner of Sims
Crane, said, “We are honoured to partner with Liebherr and be on the forefront to serve a vastly growing need for alternative energy to Sims' ever-growing customer base.” The LR 1250.1 Unplugged is one of the
first Unplugged crawler crane models to be released in the United States. Its battery can last up to approximately

eight hours based on individual workload. The machine also comes with an app that provides the status of the power of the batteries. The Unplugged series offers local zero
emissions and very little noise pollution, making this the ideal crane for Sims to work in more populated areas including amusement parks, hospitals, and residential areas, said Liebherr.
