Terex CC 2800-1 NT handed over in Brazil
By D.Ann Shiffler05 July 2010
The first Terex CC 2800-1 NT crawler crane to be delivered to Brazil was recently handed over to José Eduardo Teixeira de Carvalho Filho, director of operations for IMPSA Wind.
IMPSA Wind is dedicated to providing comprehensive, wind-power solutions from the design and manufacture of 1.5 and 2.1 MW wind turbines to their installation and maintenance worldwide.
The crane has an 84-meter main boom, light fixed jib (LF 2) and S7 kit to provide the huge lifting capacity required for the erection of wind turbines. The S7 kit consists of up to four, heavy 12-meter sections which can be mounted after the boom foot section when lighter 12-meter sections below the tip are removed.
A Superlift kit is also on order to further increase the crane's lift potential (97.5 metric ton loads lifted up to 130 meters at 138-meter hook height) on wind turbine construction sites throughout the country.
Terex Cranes developed the CC 2800-1 NT (narrow track) from the standard CC 2800-1 version, to suit specific wind farm construction requirements. Equipped with its Narrow Track chassis, the Terex CC 2800-1 NT can be driven from one construction site to the next, even when access is tight (minimum five meters) while fully rigged with counterweights, 102 meter main boom and LF 2 fixed jib, the company said.
The CC 2800-1 NT version is based on a conventional CC 2800-1, where the standard chassis (8. 4 meter track width) is replaced with the narrow track kit which includes a chassis track with 5.3 meter outer track width and front and rear outriggers, 2 outrigger pads (5 meter x 1.4 meter) for both front and rear outriggers, two side outriggers with outrigger pads (3 meter x 2.4 meter), counterweight suspension frame to lower the center gravity and control system with remote-control unit and full-color graphic display monitor at the rear of the crane chassis, the company said. For stability and short igging times, both front and rear outrigger beams remain connected to the carrier.
