Anvil Attachments, award winning manufacturer of hydraulic and cable buckets and grapples, has refreshed their line of 4 tine magnet grapples. Kyle Watson, inside sales, says, “Magnet grapples are a product that we have always had available, we just have not marketed this line.” Anvil’s engineering department took on the task of analyzing their existing magnet grapple line and making modifications to improve this product. The biggest thing was running the design through Anvil’s state of the art FEA software. Finite-Element Analysis, or FEA, is a sophisticated software program which analyzes the 3D model of the grapple. Jeff Wallace, Anvil’s engineering manager, said, “FEA software allows us to simulate the forces that will be applied to an attachment while it is working in the field. It shows us weak areas and areas that have unnecessary material; this allows our engineers to design the lightest grapple possible while keeping all the strength and integrity in place.”
Anvil then incorporated these designs and applied their LEAN manufacturing process to the manufacturing of the grapple. LEAN manufacturing reduces waste associated with manufacturing a product and, in the process, reduces errors and improves manufacturing quality. The end result from these processes is a higher-quality product at a substantial cost reduction.
Anvil’s four tine magnet grapple is available in sizes from one cubic yard to two cubic yards with various magnet sizes based on customer needs. Anvil can also design and manufacture capacities outside of these ranges on request.
Anvil Attachments is putting the final touches on the latest addition to their diesel hydraulic line, the Diesel Hydraulic Clamshell Bucket. Anvil’s Diesel Hydraulic Scrap Grapple has been a tremendous success and Anvil is excited by the addition of the Clamshell Bucket to their lineup.
Diesel powered hydraulic attachments are most commonly used in ports for stevedoring operations, as often the stevedoring has to depend on the ship coming to port being equipped with adequate buckets or grapples for unloading or loading the material. A diesel powered attachment solves this problem because the unit is totally self-contained. It is able to attach and run off any crane because the unit does not rely on the ship for hydraulic hoses or electrical power to operate the unit.
Anvil’s latest diesel hydraulic clamshell is set to ship later this month to a stevedoring operation in New Orleans, LA. This model is powered by a 140HP John Deere diesel engine. It features interchangeable bowls so that the stevedore can easily swap out the bowl bottoms depending on the material being moved. The heavy-duty bowl is 6 cubic yards for moving heavy materials up to 225 pounds per cubic foot such as pig iron and ore. The second bowl is 14 cubic yards and features Anvil’s patent pending sealed lip design for moving lighter and finer materials like sand up to 170 pounds per cubic foot. It also has spillways so the bowl auto adjusts to the weight of material handled. The engine on this unit features an external oil cooler, hydraulic oil sensors, low level fuel shutoff and electronic engine monitoring.
Anvil is also in development of a smart phone app which will let the operators and owners monitor vital statistics of the bucket such as RPM’s, temperature, fuel and oil level, tilt, G-forces applied and more. Anvil has a patent pending on this app, which should be ready in the 4th quarter of 2013.
All of Anvil’s diesel hydraulic line is available for purchase or rent. The stevedoring company that is buying the clamshell currently has Anvil’s seven cubic yard Diesel Hydraulic Scrap Grapple on rent.
Anvil’s rental fleet of hydraulic and cable buckets and grapples is now larger than ever. The rental fleet is now over 30 unit’s total. These units include hydraulic buckets, hydraulic grapples, single line buckets and Anvil’s new diesel hydraulic grapple. “The number of customers requesting rental units has increased drastically in the past year,” says Kyle Watson, Anvil’s Inside Sales Representative. Customers are looking to rent for several reasons. The most common reason is to handle a short term job, where they only have a need for a week or month, and purchasing a bucket is not cost effective. Anvil has been working hard to make material handling attachments an affordable reality to all customers.
Another popular reason customers rent from Anvil is that they offer a “rent to own” program. Under this program, a customer can rent a unit, and if needs change or their job lasts longer than originally anticipated, it may become cost effective for them to purchase. Anvil will then credit a portion of the rental fees to the purchase of the unit.
Anvil also offers a “try it before you buy it” option. A customer can rent a unit, test it, and make sure it performs for their situation and material, prior to purchasing the unit. This allows the customer to make sure this product is the perfect match for them with minimal cost and commitment.
Mr. Watson added, “Depending on the model, Anvil will also build a new unit for rental if we don’t have it in stock, with our fast lead time, we can produce a grapple in as little as a week and a hydraulic bucket in two weeks.”
Anvil offers rental options anywhere from a week to a year. And most units can ship the same day ordered. Anvil has customers all over the world and has had rental units in South America and other countries.
Anvil’s rental fleet includes hydraulic clamshell buckets in sizes ranging from 2 cubic yards through 9 cubic yards. Cable operated buckets including single line radio remote control buckets from 1/2 cubic yards to 20 cubic yards. These include cable “touch and go” buckets.
Anvil’s grapple fleet is also large, including 4 and 5 tine hydraulic grapples. Anvil also recently added its 7 cubic yard, 6 tine Diesel Hydraulic grapple to the rental fleet.

They also displayed a 4 Tine 1 Cubic Yard Grapple, a 5 Tine 1 Cubic Yard Grapple, a Multi Purpose 2 over 3 grapple, and a Quick Connect Tine for the Diesel Hydraulic Grapple.
“Wow”, the most common word heard in the Anvil booth at the ISRI trade show. Pictures and video don’t do justice to the massive Diesel Hydraulic grapple which Anvil is displaying at the ISRI trade show in Orlando. When you see this grapple in person you get a feel for the size and power this grapple demonstrates. Anvil is having a great show with lots of foot traffic through their booth, some from customers, and some from people who are just curious about the largest grapple they have ever seen. One gentlemen simply stared at the grapple for about fifteen minutes, he stated he “didn’t have a machine large enough to handle that grapple, but wanted to buy one just because it so cool.” Several people stop by just to have there picture taken with the grapple. Anvil is also displaying a 1 cubic yard 4 tine hydraulic grapple, a 1 cubic yard 5 tine hydraulic grapple and a multi-purpose two over three grapple.
Anvil Attachments updates its warranty on all clamshell buckets and orange peel grabs to one year. With this update, Anvil now has one of the best warranties in the bucket and grapple industry.
Anvil Attachment has updated its warranty on all clamshell buckets and orange peel grabs to one year. With this update, Anvil now has one of the best warranties in the bucket and grapple industry. Anvil offers the most diverse product line in the industry, ranging from hydraulic to cable / rope clamshell buckets and grapples. Most competitors in the industry, whether, hydraulic or cable offers only a six-month warranty. According to Jon Craft, President of Anvil Attachments, “The decision to move the entire product line to a one-year warranty was a no-brainer. Over the past few years, we have moved most of our product lines to a standard parts system. This has decreased our warranty issues dramatically.” Under Anvil's standard parts system, buckets and grapples are built around standard configurations and standard parts. This standard parts system is entrenched in the culture of Anvil; a lot of the parts are even cross platform between the buckets and grapples, meaning some bucket parts are also used on the grapples. This allows Anvil to stock almost all parts, allowing for next-day delivery on almost all parts.
Anvil also completely redesigned their hydraulic cylinders, Jon Craft says, “We believe we now have the best, most robust cylinder on the market.” Some of Anvil’s cylinder improvements include an inertia welded rod eye, according to Jon; this rod eye is virtually indestructible. This cylinder also features an internal cushion. Jon says, “This cushion allowed us to remove the mechanical stop that most other bucket manufacturers utilize. This cushion prevents the operator from “banging” the bucket open; this drastically prevents stresses and premature cracking on the buckets.”
Anvil's new policy warranties their products to be free from defects in material and workmanship. Over the past several years, Anvil has worked to create a culture of a service first company. Jon Craft states “I have often covered items under warranty after the warranty had expired if I believe a problem was Anvil’s responsibility. I take pride in the Anvil name, so it was just a logical step to make the longer warranty official.”
Anvil Attachments, based in Slaughter, LA, is preparing their newest product, a six tine, 7 cubic yard Diesel Hydraulic Scrap grapple for shipment to Orlando Florida for the ISRI show.
The Diesel Hydraulic Grapple is a totally self-contained unit; it easily attaches to almost any crane and is operated via remote control. Jon Craft, President of Anvil Attachments, says, “It was a major decision for Anvil to bring this grapple to the show; the logistics were complex and cost with bringing a grapple this large is high.” This grapple weighs approximately 25,000 pounds. The engineer staff at Anvil designed a special pallet to transport the grapple; the pallet needed to be substantial enough to safely support the weight of this large grapple. The pallet weighs almost 8,000 pounds on its own. This brings to total weight of the pallet and the grapple to nearly 33,000 pounds. The Diesel Hydraulic grapple is nearly 16 feet across from tine to tine when open and close to 12 feet high. To prevent from having an oversize load while shipping, Anvil will have to remove two of the tine. Anvil will bring one of the tines on another special built pallet to display their quick connect tine system.
ISRI, the Institute for Scrap Recyclers Industries show is the largest show that Anvil participates. The response and interest in Anvil’s Diesel Hydraulic Scrap grapple has been tremendous so far. Jon states, “While the cost is high in bringing a unit this large across the country, we feel its best way to get the word out on this new product.”
This ISRI show is in Orlando, Florida and runs from April 9th – 13th. In addition to the Diesel Hydraulic Grapple, Anvil will also be displaying a four tine, 1 cubic yard scrap grapple, a five tine, 1 cubic yard scrap grapple and a newly re-designed 2 over 3 grapple.
Anvil has now adopted their patented cluster sheave design across its entire line of cable buckets and grapples. Anvil received its Patent for their Cluster Sheave design in 2008; its early use was primarily on their 4 rope direct reeve clamshell buckets. The results of this design have been tremendous by increasing cable life up to 3 times.
Anvil Attachments continues to be on the forefront of bucket and grapple innovation. Anvil has learned that quality bucket design does not only come from their use of cutting-edge technology, 3D design, FEA analysis and LEAN manufacturing. The primary source of quality design comes from the customers themselves, the men who are in the field all day working with their equipment. Anvil is continually questioning their customers, asking them what they would like to see in a bucket or grapple, what don’t they like and how can we improve.
One thing that customers repeatedly stated as an issue was having to stop in the middle of a job to restring cable. This is a time-consuming and costly process. Not only is the cable expensive, but there is also the cost of downtime while unhooking the attachment, restringing, then re-hooking. This often occurs in the middle of a job, where time is money.
Jon Craft, president of Anvil, was having dinner with a large group of Kone Crane representatives in Houston. They were discussing issues with clamshell buckets, and the highest complaints have always been cracking and cable wear. Together, they all talked and drew different ideas on napkins; Jon's idea was the cluster sheaves which Anvil manufactures today.
A sheave is a wheel or roller with a groove along its edge for holding a belt, rope, or cable. When hung between two supports and equipped with a belt, rope or cable, one or more sheaves make up a pulley. The words sheave and pulley are sometimes used interchangeably. The purpose of the cluster sheave is to replace a fair lead or the standard guide rollers that have been the industry standard for years. The average guide rollers were 4 inch round and cylindrical. When the grab leans over or lists, the cable is actually rolling over a flat cylinder object. This works against all the standard criteria for adequate cable life. The cluster sheaves create a true circle in a larger diameter, similar in shape to the cable.
The patent was approved for the cluster sheave design in 2008 and, over the past five years, the results have been better than first anticipated. This design has drastically increased cable life for Anvil’s customers, doubling and tripling in most instances. Chevron in Pascagoula, MS states “Anvil has been able to double our cable life resulting in savings of over $125,000.00 per year on the cable alone.” Motiva in Port Author, Texas says “We have increased our run cycles over 200% with the new model bucket from Anvil.” And finally, Don Paulino with Kone Cranes states “We feel the Anvil product line adds value to our crane systems. It is the only bucket we will offer with our packages.”
Here is an example of the cost savings that the cluster sheaves can bring:
