Six Types Of Clam Shell Bucket Application And Advantages

December 13, 2014

No matter the clam shell bucket application, the company can derive tremendous benefit from using buckets made of superior wear and high strength steel. That is because wear and high strength steel offers the highest levels of wear and impact resistance, as well as strength, available to the aggregates industry. And since these buckets are made of several pieces that are articulated together (i.e., as explained by Wikipedia, two elementary buckets joining together from "a hinged structure and forming a claws-like appendage with an internal volume"), high strength and wear steel can help keep them functioning better and longer.

Following is a discussion of the various bucket types and why each one can extend superior advantages when constructed of high strength T1 (A514) grade and Tensalloy (AR400) steel.

1. Hydraulic Clam Shell Bucket - These types of buckets typically come in a wide range of sizes and capacities, making them amenable to many aggregates applications. Such flexibility also makes this particular kind suitable for an array of material handling functions. Because of their center rotation mechanism, hydraulic buckets require fewer parts. At the same time, each of these limited number of parts tends to be exposed to the same wear and tear. Parts made of wear steel can mitigate the damage wrought from such exposure.

2. Single Rope Cable Clam Shell Bucket - Cranes in which the holding and closing lines are shared (e.g., naval gear cranes and overhead bride cranes) often make use of an anvil attachment single rope cable clam shell bucket. This type of functionality maximizes the bucket's production capabilities, but such heavy usage can quickly result in bucket erosion. High-quality wear steel like Tensalloy AR400 is one of the best ways to eliminate these erosive tendencies and extend wear.

3. Electro Hydraulic Clam Shell Bucket - In some cranes, electric is supplied to the clam shell. These types of buckets are frequently found in ship gears and overhead gantry cranes where barge unloading and heavy handling are encountered. Wear steel can maximize the life span of this type of bucket.


4. Rehandling Clam Shell Bucket - Stock pile material that flows freely (for example, wood chips, coal and fertilizer) is often handled by this type of bucket. While it might not be obvious, these kinds of aggregates can reach weights of one ton, 3,000 pounds or more per cubic yard. High strength T1 (A514) steel is the obvious choice for living up to the demands of such heftiness.

5. Digging Clam Shell Bucket - The heaviest materials, those used during excavation, for example, can quickly challenge even the most well-built buckets. With loads like these weighing 4,000 to 6,000 pounds per cubic yard, nothing measures up to T1 (A514) steel for durability.

6. Ore Clam Shell Bucket - The mining industry often brings about the most extreme material handling situations. That is because it involves materials like pig iron, ferro-manganese, chrome ore, iron ore briquettes and nickel ore. When a bucket encounters such heavy-duty materials on a regular basis, it must be constructed of something just as strong. Using a high strength T1 (A514) grade and Tensalloy (AR400) steel can take on even the most hardcore mining applications with ease.
