Cat GSH420 and GSH520 grapples feature design refinements for power and versatility
Caterpillar has updated its GSH material-handling grapple attachment line with versatile new models designed for a wide range of applications.
The new Cat GSH420 and GSH520 orange-peel grapples, replacing the GSH15B Series grapples, are designed for applications that include handling shredded scrap such as long structural beams and car bodies, handling rocks at construction sites, and waste at recycling and transfer stations. The new grapples are designed to work with the Cat MH3022, MH3024 and MH3026 material handlers.
A statement from Caterpillar said the performance and efficiency of the new grapples help waste-handling operations, in particular, meet the challenges of increased environmental regulation, growing pressure to recycle a mix of materials, and stringent budgets.
The new grapples feature horizontal placement of the cylinders, thus creating a profile that allows for effective material penetration and efficient bulk-material handling, according to Cat. The design 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 feature a redesigned rotation system.
The new GSH Series grapples are constructed out of high-grade, impact-resistant steel that protects vulnerable areas, such as hydraulic cylinders, said Cat. For added durability, high-quality bushings with lubrication grooves and hardened pins are used in all pivot points. Tines are configured with replaceable cast tips made from BHN 445-555 material that resists wear.
In addition, Cat said it has ensured more robust build of the hinge-point construction and end-stops to provide long service life. The hydraulic hoses have also been routed within the tines to reduce hose wear. All mounting brackets feature a solid pin to keep the bracket in an upright position for ease of installation. Also, the new GSH grapples feature a standard lifting eye on the bottom of the housing for expanded versatility, such as mounting a magnet.
In terms of hydraulic systems, the new grapples feature Cat’s new HR10 rotation group, with a new swivel to significantly reduce hydraulic restriction by increasing return-flow capacity by 160% and by increasing open-flow capacity by 30%. Less restriction results in faster cycles and lower fuel burn, said the manufacturer.
Caterpillar added that it supports its work tools with a comprehensive range of pre- and after-sales services, including advice about selection, operator training, equipment management, and a range of financial and insurance products.
