Clamshell Bucket
Our Our rigorous Finite Element Analysis (FEA) testing process capable to reduce the cost 20% compare to standard design, and ensure the safe and longer operational in high-chock environments. We delivered the 12 cubic meters grabs to the port to handle the material and reduce the downtime up to 30%. Our material handling clamshell grapples increase the crane’s load and unload cycle per hour by an average of 25%.

Industry Applications
Applications used for loading and unloading bulk material from shipyards, ports, railway wagons, trucks, underwater dredging, etc. It improves the efficiency of industries like cement, mill scale, slurry, mucking, sand & gravel, coal mines, gas, steel, ports, shipyards, fertilizer, power plants, foundries, wood chips, construction, chemical plants, biomass, etc. We offer various types of grab buckets, from mechanical, hydraulic and electro-hydraulic. It can be used in any kind of environment for loading of soil, rock, hard soil, weathered granite, and hard rock.
Clamshell Bucket for Wood Chips & Grain
Clamshell buckets handle the agricultural work efficiently. The clamshell bucket base is designed to load and unload material with a total capacity of 2500 L. Our construction equipment ensure the maximum strength and reliability during operation.
Clamshell Bucket for Excavators
Clamshell buckets handle the loading & unloading of construction and industrial waste, grain, sand, rocks & so forth in addition to digging & dredging activities. A clamshell bucket for excavator can be mounted on heavy-duty machines or equipment with optional features with or without a rotator (360°).
Clamshell Buckets for Ship Cranes
It is designed to handle powder & fine bulk materials such as chemicals, fertilizer, grain, coal, coke, iron ore, sand, particle construction materials & smashed rocks, etc. Radio remote control grabs are useful for underwater digging in shipyards, marine environments, etc.
Clamshell Bucket for EOT Crane
We are manufacturers of clamshell buckets for cranes and supplies in cement industries. These applications are ideal for the cement industry, ship industry, chemical industry, & construction industry. Therefore, electro-hydraulic grab bucket can easily handle heavy workloads. In addition, our clamshell bucket upgrades your overhead crane process for the productivity of business. We have spent a long time involved in providing different custom grabs for this extraordinary work. We design clamshell bucket from 0.75 cbm to a customized range for the crane after that, the process of FEA tests, which allow us to enhance the quality of the product & makes more prominent.
Clamshell Bucket for Underwater Dredging
APR Industries delivers high-quality material handling ship grabs, vessel grabs, and solutions to the ship ports, cargo, marine, shore, offshore, and underwater dredging. The clamshell bucket has the ability to handle the various types of underwater dredging because it is made with corrosion-resistant materials and sealed components. Our grab is suitable for loading material and groundwork, and grabs are designed to work for different applications. We design clamshell buckets using hydraulic cylinders that help to make the operation successful with strong digging force.

Frequently Asked Question
Q: What is the estimated Return on Investment (ROI) of upgrading to one of your clamshell grabs?
Ans: Exact ROI depend upon the operations, our grabs bucket ensure the maximum efficiency and reliability. Also, as per our customers feedback, 20-27% increase in unload cycles per hour compared to other mechanical machines. Our grab bucket introduced the faster duty cycle, precise position, and up to 20% reduction in material leakage.
Q: How does the design of your clamshell bucket minimize material spillage during operation?
Ans: We follow the Indian and International design standards and provide the optimal close strength, ensure the tight seal to handle material like fertilizer or fine coal. For other material like power, we develop the grabs bucket with lead and CRD (Cylinder Rod Dust Protector) system for continuous operation.
Q: My excavator is used for demolition and large rock handling. Which grab is the best fit?
Ans: We designs and develop hydraulic clamshell bucket featuring a 360° rotator option and rugged EN19 teeth. Built-in hydraulic mechanism provides the digging force for hard rock, granite, and rotator supports the precise placement and easy to load an unload the irregular shapes demolition waste also.
Q: What are the main components of the grabs hydraulic system, and what is maintenance required for a grapple?
Ans: We design and develop the grab bucket with high-quality components including hydraulic cylinder(s), motor /pump, oil tank etc. A daily inspection to check the lubrications, cylinders seals , wear and tear plates(Hardox), pins and bushes to check properly for durability of grab.
