Clamshell Crane

Clamshell Crane is a heavy duty overhead crane equipped with Clamshell Bucket, which can be used frequently. The lifting capacity of clamshell crane is consisted of the load weight and the dead weight of the crane bucket, which is from 5 ton to 25 tons.

The main specifications of clamshell bucket cranes are for your reference:

• Product Type of Clamshell Crane: QZ
• Lifting Capacity of Clamshell Crane: 5~25t
• Span Length of Clamshell Crane : 10.5~34.5m
• Working Class of Clamshell Crane: A6

Advantage and features of Clamshell Crane

Ideally designed Clamshell cranes with automatic, semiautomatic, and manual control are widely used in various industrial applications.

• The grab overhead crane is equipped with laser-assisted height measurement.
• Clamshell Cranes can work around the clock.
• For safe lifting and traveling, safety protection devices such as limit switches for lift and CT are installed.
• The Overload Protection Device improves overall performance security.
• Remote control of Clamshell Cranes allows for simple and convenient operation.
• Our Clamshell Cranes have a better working performance in terms of precision because they are equipped with a double speed mechanism.
• Clamshell Cranes are outfitted with low voltage protection, phase sequence protection, and an emergency stop device.

There are warning indicators installed, including flashing lights and a warning sound.

Application of Clamshell Crane

• Clamshell Buckets are used to load and unload materials such as sands, coal, mineral powder, and bulk chemical fertilizer. The Clamshell Bucket is used to grab bulk materials on the gantry crane and overhead travelling crane.
• Clamshell Cranes are widely used to load and unload scattered objects in power stations, storage, smelting workshops of steel mills, ports, cement plants, and waste recycling stations, among other places.
• The Clamshell Crane has high heat, dust, and aggressive environment requirements.
• EOTCRANEKIT can recommend the best Clamshell Crane for your needs.

Types of Clam Shell Buckets & Application

Using buckets made of superior wear and high strength steel can provide significant benefits to the company regardless of the clam shell bucket application. This is because wear and high strength steel provides the aggregates industry with the highest levels of wear and impact resistance, as well as strength. And, because these buckets are made up of several articulated pieces (i.e., 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 them function better and last longer.

• Hydraulic Clam Shell Bucket - These buckets are available in a variety of sizes and capacities, making them suitable for a wide range of aggregate applications. Because of its versatility, this kind of crane grab is appropriate for a wide range of material handling applications. Hydraulic buckets have fewer parts due to its center rotation mechanism. At the same time, each of these few parts is subjected to the same amount of wear and tear. Wear steel parts can help to reduce the damage caused by such exposure.
• Single Rope Cable Clam Shell Bucket - Anvil attachment single rope cable clam shell buckets are commonly used on cranes with shared holding and closing lines (e.g., naval gear cranes and overhead bride cranes). Although this type of capability enhances the bucket's production potential, heavy use can quickly erode the bucket. One of the greatest methods to eliminate these erosive tendencies and extend wear is to use a high-quality wear steel like Tensalloy AR400.
• Electro Hydraulic Clam Shell Bucket - In some cranes, the clam shell is powered by electricity. When barge unloading and heavy handling are required, these buckets are typically used in ship gears and overhead gantry cranes. This bucket's life can be extended by using wear steel.
• Rehandling Clam Shell Bucket - This sort of bucket is commonly used to handle stockpiled material that flows freely (for example, wood chips, coal, and fertilizer). While it may not be immediately apparent, these aggregates can weigh up to one ton, 3,000 pounds, or more per cubic yard. The logical choice for meeting the demands of such heftiness is high strength T1 (A514) steel.
• Clam Shell Bucket for Digging - The heaviest materials, such as those used in excavation, can quickly overwhelm even the best-built buckets. Nothing beats T1 (A514) steel for durability when dealing with loads weighing 4,000 to 6,000 pounds per cubic yard.
• Ore Clam Shell Bucket - Material handling settings in the mining industry are frequently extreme. Pig iron, ferro-manganese, chrome ore, iron ore briquettes, and nickel ore are among the materials used. When a bucket is regularly exposed to such heavy-duty materials, it needs to be made of the same material. Tensalloy (AR400) steel and high-strength T1 (A514) steel can handle even the most demanding mining applications.
