By Alex Dahm23 February 2011
The CTT 321 is a new 300 tonne-metre class flat top tower crane from Terex Cranes.
Capacity is 16 tonnes and the boom can be configured in 5 m increments from 30 to 75 m. It has the new EVO 15 operator cab with colour ICS display and new ergonomic joystick controls. Winch options are 45 or 67 kW.
CTT 321 is designed for easy transport and installation. The two-part counter jib can be transported with the longest component at 8.7 m. The counter jib can be mounted from the ground using the pins for jib assembly. The cabin platform is pre-assembled for quick set-up at the jobsite.
Included as standard is an anti-sway module, a slip-ring protection bar and rods, and jib safety rope to protect workers from falls when working at height. A trolley device has also been introduced to prevent the pulley rope from jumping the reeving track. Also standard is a new automatic slewing ring greasing system. An anti-collision and zoning system is available.
