Terex Cranes has introduced it's newest addition to its growing tower crane family, the Terex® CTT 472-20 flat top tower crane. This new Terex 20-tonne (22-U.S.-ton) class crane expands maximum jib length to 80 m (262.5 ft) and increases load charts over previous models offering the same lift capacity on the whole jib length, with a maximum load at the full length of the jib tip of 4 tonnes (4.4 U.S. tons).
"Fresh off the introduction of our new hammerhead tower crane at CONEXPO-CON/AGG, we offer our customers the new CTT 472-20, an extremely versatile and robust flat top tower crane with great features requested by our customers. The CTT 472-20 gives the market a flexible solution to meet complex lifting challenges," says Marco Gentilini, vice president and general manager for Terex Tower Cranes. "With Terex fully committed to the tower crane business, we are accelerating new tower crane product development to meet our customers' needs. This includes a new tower crane cabin that will advance operating efficiency and comfort for our new CTT 472-20 crane."
Offering a 470 ton-meter load moment, the new CTT 472-20 crane delivers extremely high lift capacities throughout its load chart and 11 different jib configurations from 30 to 80 m (98.4 to 262.5 ft) to meet varying jobsite needs. Its hoist, slewing and trolley speeds allow operators to quickly and precisely move and position heavy loads. All jib sections come preassembled with a life line for quick, safe installation at height, while galvanized jib walkways deliver long-lasting quality.
The CTT 472-20 can be configured with H20, HD23 and TS212 Terex mast section or thanks to the transfer masts with the combination of them. "Here, Terex offers superior value for the customer, as this gives companies operating multiple Terex tower crane models the ability to efficiently manage component inventory and cost effectively meet their tower needs," adds Gentilini.
The new CTT 472-20 flat top tower crane offers a very competitive maximum freestanding height to reduce erection time and lower costs. Optimized for transport, these tower segments come preassembled with aluminum ladders for fast erection and increased durability.
The new CTT 472-20 is the first tower crane model to include the new Terex cabin that will be installed on all flat top, hammerhead and luffing jib models. It puts the operator in the lap of luxury with a fully adjustable comfort seat and joystick controls with short stroke length providing a pleasant and comfortable working environment. The large full-color 18-cm (7-in) display with anti-glare screen provides critical operating data and information required for troubleshooting. Built-in heating and air conditioning maintains consistent cabin temperature, regardless if operating in winter temperatures or the heat of summer.
A new control system found on the CTT 472-20 crane offers expanded configuration options to meet different jobsite needs. Offering quick set-up, the new controls boast the exclusive Terex Power Plus feature that can temporary increase the maximum load moment under controlled conditions (e.g. smooth hoist movements) giving the operator extra lifting capacity, by an additional 10%, when needed. Power match allows the operator to choose between operating performance or lower consumption to fit lifting needs. An optional radio remote control expands crane operating efficiency by giving the operator a choice in how he wants to work.
