Cat GSH420 and GSH520 orange-peel grapples, replacing the GSH15B Series grapples, are designed for a wide range of applications, including handling waste at recycling and transfer stations, shredded scrap, and rocks at construction sites. They are designed to work with the Cat MH3022, MH3024, and MH3026 material handlers.
The new grapples feature horizontal placement of the cylinders, thus creating a profile that allows for effective material penetration and efficient bulk-material handling. The grapples are available in four-tine and five-tine shell configurations and in closed or semi-open versions.
The design of the GSH Series grapples features construction of high-grade, impact-resistant steel that protects vulnerable areas, such as hydraulic cylinders. 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.
The new HR10 rotation group, featuring a new swivel, reduces 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.
