Caterpillar introduce new grapples for bulk material handling

Cat grapple

Latest GSH420 and GSH520 units feature design refinements for improved performance

THE new Cat GSH420 and GSH520 orange-peel grapples – replacing their GSH15B Series predecessor – are designed for a wide range of applications, including handling rocks on construction sites and waste at recycling and transfer stations. 

The performance and efficiency of the Caterpillar grapples help improve waste-handling operations, in particular, meeting the challenges of increased environmental regulation, growing pressure to recycle a mix of materials and stringent budgets.


The GSH420 and GSH520 grapples feature horizontal placement of the cylinders, thus creating a profile that allows for effective material penetration and efficient bulk material handling. The design also enhances the strength, reliability and durability of the new grapples, which are available in four-tine and five-tine shell configurations and in closed or semi-open versions. 

In addition, the GSH420 and GSH520 units feature a redesigned rotation system and they have been specially developed to work with the Caterpillar MH3022, MH3024, and MH3026 material handlers.

For long-term durability, the GSH Series grapples are constructed in high-grade, impact-resistant steel that protects vulnerable areas, such as hydraulic cylinders. The machine attachments also include high-quality bushings with lubrication grooves and hardened pins used in all pivot points. Tines are configured with replaceable cast tips made from wear-resistant BHN 445-555 material.

In addition, solid hinge-point construction and robust end-stops ensure long service life, and routing hydraulic hoses within the tines reduces hose wear. All mounting brackets feature a solid pin to keep the bracket in an upright position for ease of installation.

The GSH grapples also feature a standard lifting eye at the bottom of the housing for expanded versatility, such as mounting a magnet.
