Self-contained grapple has been designed for material handling from ships and barges.
Anvil Attachments, Slaughter, La., has debuted its latest product offering, a completely self-contained, diesel-powered hydraulic scrap grapple.
More than a year in design and development, Anvil’s model DHSG grapple is intended for material handling from ships and barges where hydraulics or electricity are not options. The diesel hydraulic scrap grapple attaches to any crane that can support the weight, Anvil says. It is suited for handling a wide range of products including scrap, stone blocks, rip-rap and pig iron.
The company says it developed the diesel hydraulic scrap grapple to fill a need of bulk material handlers who needed a completely self-contained grapple where standard hydraulic or electro-hydraulic would not fit.
“Our goal was to get the design right the first time, that is why we spent over a year on design and development,” says Jon Craft, president of Anvil Attachments. “Our engineers used our Finite-Element Analysis software to its full capabilities; this way we ensure that this grapple provides maximum strength and payload for the weight. Based off of our initial field test and customer feedback, we got it right. Our first unit sold was immediately thrown into the fire, moving foot long pieces of pig iron, one of the toughest types of materials to handle, and our diesel grapple has worked with barely a glitch.”
Anvil's diesel hydraulic scrap grapple can be configured with either a turbo-charged air cooled diesel engine or water-cooled diesel engine, depending on the user’s environment. The engines range up to 150 horsepower. The grapple has several engine access panels for easy access and maintenance.
The grapple tines are completely configurable to user and material handling preference, with five-tine options from small-blade, to lower enclosed, up to full enclosed. The tines are modular and crafted using high strength alloy steel for maximum wear resistance, and every tine is powered with a 5-inch cylinder Anvil says. The custom-designed cylinders feature inertia welded rod eyes for maximum strength, the company says.
The grapple has an easy pin adapter that connects to virtually any crane, according to Anvil. Once connected to the crane, the grapple engine is started, and opening and closing is all controlled through a simple remote control unit that works up to 500 feet away. Anvil is currently developing a smart phone app that will allow the monitoring of all vital engine statistics; this should be ready in the first quarter of 2013.
Anvil adds that compared to the competition, its grapple experiences no overheating issues. The grapple burns two-thirds less fuel, has throttle control, a 50-gallon fuel tank with low level shutdown, all while handling pig iron.
In addition, Anvil currently has a diesel-powered clamshell bucket in production. This bucket will use many of the same concepts and parts as the grapple.
Anvil's diesel powered hydraulic scrap grapple is available for sales or rent.
