Mecalac launches hydraulic thumb attachments for 6MCR and 7MWR Excavators

Mecalac Construction Equipment UK has launched a factory-designed hydraulic thumb attachment, suitable for its 6MCR crawler-skid excavator and 7MWR wheeled excavator with two-piece boom. The hydraulic thumb makes it significantly easier and faster to hold and move large or long objects, designed for a variety of handling applications. It allows for precise operation and placement thanks to proportional control via the excavator’s right joystick thumbwheel. The thumb is comprised of four stainless steel tines and has manual shut-off valves on both sides of the cylinder to isolate the attachment when not in use. The attachment is controlled via the first auxiliary line (high flow) and does not require safety check valves.
