VIDEO: Mecalac Hydraulic Thumb Increases Material Handling Ease

Tue April 20, 2021 - National Edition

Mecalac, a global designer, manufacturer and distributor of compact construction equipment for urban environments, offers a new hydraulic thumb option for its recently re-configured two-piece boom with offset, available for 6MCR skid excavators and 7MWR wheeled excavator models.

The new thumb makes it easy to pick up, maintain and move large or long objects, transforming material handling capabilities for applications such as truck loading or pipe laying. This makes it ideal for contractors in a number of industries including utilities, landscaping, road maintenance and general construction, according to the manufacturer.

"Mecalac believes a machine that doesn't make an operator's life easier has no place on the job site," said Peter Bigwood, general manager of Mecalac North America. "The hydraulic thumb not only increases productivity, it keeps workers safer and makes their lives easier."

The hydraulic thumb option permanently mounts to the bucket linkage where it is powered by the boom's hydraulic cylinder. Unlike grappling buckets or other attachments that must be dismantled during other operations, the new hydraulic thumb can remain attached during digging work or other tasks. The thumb is composed of four teeth and is compatible with Mecalac's CONNECT hydraulic quick coupler. When engaged, the constant pressure exerted on the thumb throughout the cylinders stroke ensures precise control of the load, allowing operators to efficiently move boulders, pipes and other cumbersome objects without leaving the cab or changing the attachment.

The new hydraulic thumb option is available on 6MCR and 7MWR models with Mecalac's two-piece boom with offset and can be added to existing models with this boom, as well. This variation of Mecalac's boom design maintains the large range of motion and lifting force. Additionally, positioning the stick cylinder above the boom, rather than underneath, provides a wider working angle, faster movement and a higher penetration force that is ideal for excavation and truck loading applications, according to the manufacturer.

Dimensions and work envelope remain similar to the standard boom, and attachments, such as loader buckets and pallet forks, are still compatible.
