The system is also used for remote control of the hydraulic erection device to assemble the swing-away jib.Terex RT 100 Crane Overview and Specifications The remote control makes it easier for the operator because previously the motions could only be made from the crane cabin so the hook block could only be seen via a mirror or a second person was needed to give instructions. The crane driver can attach and detach the hook block at the front bumper via remote control for the hoist winch and luffing cylinder. The LTM 1100-4.2 has the new Liebherr LICCON2 crane control system. Outrigger spread is 7 m and, for job sites where space is restricted, it is possible to work with a reduced supporting width of 5 m. The tail swing of the counterweight, up to 28.2 tonnes, stays within 4.11 m. Up to four motions can be driven simultaneously.
In the superstructure is a Liebherr four-cylinder inline 129 kW (175 hp) engine to power the hydraulic pumps for the upper crane works. A two-stage transfer box gives crawl speeds for manoeuvring. Power is from a six-cylinder 350 kW (476 hp) Liebherr inline diesel driving through a 12-speed ZF-AS-Tronic automated manual gearbox with intarder. The carrier has air operated disc brakes and rear axle steering. On 16.00 R 25 tyres the 10.6 m long carrier is 2.75 m wide and its turning radius, measured over the carrier cab, is 8.3 m. The swing away jib can be set at 0°, 20° and 40° and there is a hydraulic option where the jib can be luffed under full load between 0° and 40°. Two lattice sections, each 7 m long, and the 10.8 – 19 m long swing-away jib give the LTM 1100-4.2 a hook height of 91 m and a radius of 58 m. The boom is six telescopic sections plus the base section and is extended and retracted using the Telematik telescopic system. Capacity with the boom fully extended is 10.2 tonnes and the strongest four-axle crane in the market, Liebherr said. The new crane is also stronger, especially with the boom fully telescoped and in a steep position, where increases are about 30%, the manufacturer said. Its 60 m boom exceeds its predecessor’s by 8 m.
