CM SERIES - A micro clamshell for excavator use

Micro in size, massive in performance. Unlike most small clamshells, the CM series is specifically designed for excavator fitting and is built to withstand the downward pressures exerted by the excavator during digging operations.

The CM series clamshell is specifically designed to fit between railway sleepers and rails, with a total width of 230mm.

Ideal for 'wet bed' work and cable laying trench digging.


Like all Powerhand products the CM series is designed and built in house

We understand that the only way to guarantee the best quality is to control the whole process. That is why we complete 100% of design and manufacture in our factory in Scotland.

We are proud to never be satisfied and are constantly seeking to improve our concepts and to be at the forefront of manufacturing technology.

For over 30 years we have developed and refined our attachments in collaboration with many of the industries' leading users, with the aim of delivering the ultimate end product and customer experience.

world class Rotations

World leading attachments require world leading rotators... that is why we use Indexator rotators to partner our Powerhand attachments

We think of our attachments as the hand at the end of the machine boom and the rotator as the wrist. For unbeatable completion of the task and minimal downtime, both must be of the highest quality.

Powerhand has established a close working relationship with Indexator over the last 30 years, who lead the world in rotator design and manufacture the widest range of rotator products. They employ the most advanced design and manufacturing systems available, with industry leading testing systems used to rigorously test components after final assembly. This is all to ensure that the most durable rotators possible are created!

The CM series is fitted with Indexators GV series rotators as standard.

Final Link in the chain

Often an afterthought in 'end of arm' attachment assemblies, the rotator to boom connection link plays a very important role.

We are proud to offer the whole 'end of arm' package. From attachment, to rotator and link. Powerhand offers a range of industrial excavator and material handler links for a wide variety of machines and applications.

Links are available as standard, swing dampening, or for fixed mount applications. We also offer the service of creating a link to your bespoke order. For any machine, for any application, we can manufacture a link to your specification.
