Terex has introduced a new six-axle, 360-ton-class all terrain crane, the Demag AC 300-6. The AT crane is a brand new model, designed from the ground up, and it will replace the AC 250-6 in the Demag product line. It is also the smallest AT crane in the Demag range equipped with a luffing jib. Key applications are tower crane erection, construction, equipment removal, and refinery refurbishments and replacement work.
The Demag AC 300-6 AT crane features a 262.5-foot main boom can perform jobs at heights up to 255 feet or a 242-foot radius without rigging a jib. It has a 16.5-ton capacity when the main boom, making it ideal for tower crane erection. Also, the Demag AC 300-6’s luffing jib allows customers to lift loads with more offset than the regular main boom extension jib. According to Terex, this is especially useful to fly over a building and place the load behind it, or fly over railroad tracks. The luffing jib bringing the maximum system length to 387 feet, and it uses the same luffing jib rigging system as the AC 350-6 and AC 1000-9 cranes.
Innovations incorporated in the crane include IC-1 Plus control system and single-engine design concept with an intelligent motor management system, which enhance productivity and help reduce operating costs. The IC-1 Plus control system provides real time calculation of the lifting capacities and supports operators in safe crane operation. It also allows asymmetric outrigger positioning. The Demag AC 300-6’s single engine has a start and stop function to reduce idle times and total engine hours, contributing to the reduction of fuel costs and preserving the crane’s residual value.
The Demag AC 300-6 helps maintain a lower stock of spare parts because it uses a high number of interchangeable parts with the Demag five-axle family all-terrain cranes. Furthermore the 68.9-foot double folding main boom extension of the five-axle Demag is compatible with the AC 300-6.
The compact design of the Demag AC 300-6 all terrain crane features a carrier length of 50.1 feet and a width of 9.8 feet. The crane is easy to position on the jobsite, thanks to its active all-wheel steering.
On the road, the Demag AC 300-6 crane meets axle load limits from below 13.2 US tons up to 17.6 US tons and can travel up to 53 mph. It also has 1,764 lbs. of extra payload capacity for carrying extra lifting accessories. It includes an axle load monitor, displayed on the dashboard, to help customers drive within the road-legal weight. This model, like all Demag cranes in this product family, can be configured to comply with the variable axle weight limits in most states of North America and many other countries by connecting different types of boom dollies or removing the boom.
First deliveries of the AC 300-6 is expected in the first half of 2018.
