What's New In Plant & Equipment

Sennebogen Crane For Well Drilling And Mobile Pipe WorkSennebogen Crane For Well Drilling And Mobile Pipe Work

If numerous holes must be drilled at short intervals, or if the work must be accomplished in tight spaces, a small and flexible duty cycle crane is ideal.

In the fall of 2016, Sennebogen will introduce the new 624. A compact basic unit that is quickly available for the installation to piping machines and for rope operations. The new machine will be referred to as “taxi” duty cycle crane and uses a foldable box-type boom that can be assembled into its transport position in three simple steps.

Foldable boom safes time and space

This simple technology makes it possible to have the crane ready in only a few minutes. The operator requires only a few steps to have the machine ready, operate it, and subsequently load the machine back onto the truck. This allows the machine not only to be employed in the tightest spaces, but it can also be transported very fast from one construction site to the next.

During the transport, the boom is folded next to the cab and alongside the uppercarriage. This saves time and space during the assembly. The boom can be extended to a maximum length of 19 m. Two 6 t free-fall winches in the uppercarriage provide the necessary tractive force. The individually adjustable free-fall brake makes the operation simple and easy.

Mobile variant or crawler drive

With an operating weight of 27 t and a design that qualifies it to be used as a full-fledged duty cycle crane, the new crane is remarkable in its performance class under 30 t – a unique characteristics that opens a multitude of potential applications. In the future, two variants of the undercarriage will be available.

A robust crawler undercarriage provides maximum stability and manoeuvrability in any terrain.
A variant with tyres and outriggers for pipe installations in the downtown area.

The 27 t duty cycle crane will also be used in the future to close the gap in water engineering applications. Due to its low operating weight, the machine can be easily installed on pontoons or barges and employed for all types of water conservation applications and maintenance tasks

All the cranes from the CM1600 Series feature flat-top design, frequency controlled mechanisms, different options of hoist speeds and the PowerLift system.

This new CM1600 Series allows Comansa CM to fill the gap between the CM1100 Series (with max. loads of 6 and 8 tonnes) and the CM2100 Series (up to 25 tonnnes of maximum load capacity). According to Sales Manager, Mr. Andy Huang,

“Comansa CM’s range is now even more complete and allows us to be part of all types of projects, from small residential to large-scale industrial and infrastructures”.
