Featuring a lifting capacity of 650 m at a radius of 12 m and a maximum load moment of 9,152 meter-tonnes, the Demag CC 3800-1 lattice boom crawler crane is a cost-effective option for various projects. It is also suitable for erecting wind turbines with a hub height of up to 117 m without a Superlift system.
The Demag CC 3800-1 comes with a 144-m main boom. However, the crane’s maximum system length can be extended all the way up to 171 m with the optional boom booster. The welded steel structure consists of up to seven sections with a length of 12 m and is designed to be directly mounted on the crane. It also boosts the main boom’s stiffness, further increasing its lifting capacity.
When equipped with the boom booster and a lightweight rigid lattice jib, the CC 3800-1 can reach a maximum hook height of 185 m and lift loads of up to 71.5 t. Thus, the crane can tackle lifts that would normally be handled by cranes in the 750-t class.
With the optional ‘Fall Protection Device’, the CC 3800-1 offers maximum safety during setup and disassembly. So if a person on the lifeline falls, the system is able to arrest their fall at a large distance from the ground, significantly lowering the risk of injury.
The Superlift Split Tray, which is also optional, features quick coupling technology that makes it possible to easily uncouple the counterweight that is no longer needed after erecting the main boom. After doing this, the crane can simply move with the Superlift counterweight that is actually needed, saving assembly time, minimising the amount of personnel needed, and eliminating the need for an assist crane.
The optional Flex Frame unit can be used to replace the standard telescopic cylinder. As such, the Superlift counterweight radius can be adjusted to any dimension between 13 m and 21 m with the full counterweight. This means less counterweight needs to be set up and removed, significantly reducing setup times.
Available as Demag PC 3800-1 pedestal crane
Demag also offers the CC 3800-1 crawler crane in a different form as the PC 3800-1 pedestal crane, which outdoes its ‘brother’ by 100 meter-tonnes with a load moment of 9,252 meter-tonnes. The Demag PC 3800-1 is available as a complete crane or as an additional carrier, and the quick coupling system makes it possible to easily switch between the crawler and pedestal carriers.
A Demag PC 3800-1 equipped with axle lines can be easily configured for an axle load limit of 12 t or a total vehicle weight of less than 100 t, depending on the relevant regulations determining whether a vehicle is street-legal.
At the work site, a 390-kW Mercedes Benz diesel engine delivers ample power under all operating conditions. Moreover, the crawler tracks can be controlled independently of each other, as well as in opposite directions, with a tractive force of 1,400 kN per side.
