Detailed Product Description

• Suitable for all excavators from 4 to 17 tonnes in weight
• Rugged construction to suit the toughest conditions
• Rugged hydraulic cylinder with pivot-mounted eyes heavy-duty execution
• Thumb teeth in hard-wearing-resistant HARDOX®-steel
• Lubricating nipples are countersunk and therefore well-protected against damage
• Large working range of up to 180°
• Low-wear, low-maintenance mountings (hydrodynamic bearings)
• Clamping force of 1.1 to 7.4 tonnes (depending on operating pressure and cylinder size)
• Attachment for securing, holding and handling loose and bulky materials.

The MARTIN thumb is a highly-innovative development.

The progressive approach in kinematics increases the clamping forcemaking it safer and more efficient. Bulky materials can be handled moreeasily, more safely and therefore more efficiently.

Benefits

Used in conjunction with the MARTIN Quick Coupler, the thumbconstitutes a proven additional application which enhances theflexibility of the excavator. Manufactured to high quality standards,the thumb can be used anywhere on the construction site. As it ispermanently fixed to the excavator, it is always for use.

• The thumb teeth are based on a modular system and adaptable to suit any bucket.
• The countersunk lubri-cating nipples can withstand the most gruelling conditions and are readily available for maintenance purposes.
• The pivot-mounted cylinder eyes prevent distortion of the construction, greatly enhancing the service life of the hydraulic cylinder.
  
• he linear hydrodynamic bearings are low-maintenance and reduce friction at the bearing points to a minimum.
