Features

  • Vertically Perforated Side Plates

    Vertically Perforated Side Plates

    Better load visibility and easier positioning. Plates are hardened to HB450 standards providing higher wear resistance.

  • Specially Designed Pins

    Specially Designed Pins

    Oversized pins have high resistance against torque forces and increased durability. Grooved bushings allow for easy greasing.

  • Optimally Designed Linkage

    Optimally Designed Linkage

    Minimal height increase when opening and closing. Optimal cylinder guidance ensures high clamp forces during closing.

  • Oversized Cylinder with Load Holding Valve

    Oversized Cylinder with Load Holding Valve

    Ensures even, high clamping force to prevent loss of load. Load holding valve keeps clamp force constant even when maneuvering grapple or machine to ensure controlled load movement.

  • Slim Design

    Slim Design

    Easier maneuvering within building construction or containers in demolition and recycling applications. Optimal jumper lines routing avoids damage.

  • Robust Bolt-on Cutting Edge

    Robust Bolt-on Cutting Edge

    Provides high wear lifetime. Plow bolts utilize recessed nuts and are fully protected.

  • High Displacement Motor

    High Displacement Motor

    Robust hydraulic design maximizes rotation torque and optimizes rotation speed.

  • Widest Frame in Class

    Widest Frame in Class

    Strong design protects internal components from debris damage.

  • Oval Service Access Panels

    Oval Service Access Panels

    Easy service through two access panels; one on front and one on back.
