The new Strong-Arm grapple from Barko is designed for seamless integration with the company’s loaders to offer powerful rotation torque and clamping force.
The grapple is engineered as a solution for log handling and delimbing applications. The attachments was created to optimize the performance of Barko B-Series loaders – including all trailer/truck mount, tracked, rough terrain carrier and stationary loader models.
The Strong-Arm Grapple line up consists of three models. The 4250, 4850 and 5250 grapples have maximum openings of 106 cm, 122 cm and 132 cm, respectively, with each rated for up to 22,679 kg of lift capacity.
A compact rotator allows for hoses to be contained in a single bundle between the boom and grapple, providing better hose protection. Other features include 360-degree continuous rotation and a fully supported rotator drive pinion gear.
The hydraulic motor is designed to maximize hydraulic flow, making each grapple fast and productive, according to Barko. By minimizing flow restriction, horsepower efficiency is enhanced, allowing operators to accomplish more while maintaining optimal fuel economy.
The motor design features internal components that were tested and sized specifically to tolerate tougher conditions. An internal relief cartridge is completely integrated with the motor to avoid damage and oil leaks.
The Strong-Arm grapples are constructed of high tensile, wear-resistant steel and include hard face welding on the arm tips to extend working life.
As well, oversized, induction-hardened pins help reduce wear to the grapple’s pins and bushings. Cushioned cylinders help eliminate jarring effects at maximum open and close, while thick cylinder walls provide further durability. Additionally, load holding valves in the cylinders are guarded to prevent damage and enhance safety.
A service-friendly design includes four convenient inspection plates for the grapple collector and hoses, along with 12 easily accessible grease points.
