Product Snapshot: Tower Crane and Backhoe
The largest standard crane available from Liebherr, the 1000 EC-H is a 40-metric-ton-class tower crane. It has a maximum lift capacity of 11,500 kiloggrams at the tip and a working radius of 80 meters. It is available in two-fall 20-metric-ton and 25-metric-ton versions, with maximum lift capacities of 40 metric tons and 50 metric tons, respectively. The connections on the tower segments have been redesigned to reduce wear, allowing the crane's tower to retain its strength even if it is erected and dismantled regularly. The Liebherr Connect and Work quick-release fastening system is a standard feature to reduce erection times.

In addition to a standard side handle, the tool also features an ergonomic grip area on the hammer tube for greater control. The tool can handle a variety of applications, including removing wall and floor tiles, repairing joints and cutting slots in concrete or masonry.

The Terex TLB890 Backhoe features a curved boom that allows for trucks to be positioned closer during loading, resulting in shorter cycle times. The backhoe's dipper boasts a tear-out force of 41.1 kN when retracted and 29 kN when fully extended. It is available with a pilot control system or mechanical lever controls in SAE, ISO or cross-pattern configurations. It has a maximum traveling speed of 25.6 mph and features large-diameter, wet-disc brakes.
