Terex Cranes has expanded its tower-crane range with the new CTT 472-20 flat-top tower crane. The new 22-ton-class crane expands maximum jib length to 262.5 feet and provides a maximum load at the full length of the jib tip of 4.4 tons. With a 470 ton-meter load moment, the new CTT 472-20 delivers high lift capacities throughout its load chart, says Terex, and 11 different jib configurations, from 98.4 to 262.5 feet, meet varying job-site needs. All jib sections are pre-assembled with a life line to facilitate installation at height; galvanized jib walkways resist corrosion. The new crane is designed to provide competitive, maximum, freestanding height to reduce erection time and lower costs. Optimized for transport, tower segments are pre-assembled with aluminum ladders for fast erection and increased durability.
The CTT 472-20 is the first Terex tower-crane model to include the new Terex cabin, which will be installed on all flat-top, hammerhead, and luffing-jib models. The new cabin features a fully adjustable comfort seat, joystick controls, and full-color 7-inch display that provides operating and trouble-shooting information. Built-in heating and air conditioning maintains consistent cabin temperatures. The new control system provides expanded configuration options to meet differing jobsite needs and includes the Terex Power Plus feature, which can temporarily increase the maximum load-moment by 10 percent under controlled conditions. Optional radio remote control expands the crane’s operating efficiency.
