What Is Electric Hydraulic Multi-petal Grab Bucket?

Le Electric Hydraulic Multi-Petal Grab Bucket is a high-performance attachment designed for electric hoists and ponts roulants. With a lifting capacity of 3.2–30 tons and a grab weight of 1.5–11 tons, it excels at scooping, gripping, and transporting bulk materials — from scrap metal and scrap steel to sand, gravel, and construction debris. The hydraulic-driven multi-petal design ensures a firm, even grip on irregular loads, making it indispensable for material handling operations in demanding industrial environments.

Dafang Electric Hydraulic Grab Bucket (clamshell grab bucket) is usually used as a spreader for overhead cranes or grues à portique, to complete the material gripping work. The grab bucket has an electric or hydraulic system to ensure that it has a large gripping force. Its core structure consists of a number of jaws to adapt the needs of different kinds of material gripping.

According to the operation mode, it has three types of single-rope, double-rope and four-rope grabs. Single rope means that a single wire rope control the opening and closing. Double rope refers to the use of two wire rope to control the suspension and opening and closing respectively. And four ropes refers to the configuration of four wire rope to control opening and closing. This orange peel grab has become an indispensable equipment in industry and logistics due to its clever structural design and high flexibility.

FAQs About Multi Petal Grab Buckets

Q1: What's the difference between lifting capacity and grab weight?

A: Lifting capacity is the maximum load the grab bucket itself can safely lift (including the weight of the material). Grab weight is the weight of the empty grab bucket mechanism. The actual payload capacity = lifting capacity − grab weight. Always verify the net payload meets your material weight requirements.

Q2: What materials can it handle?

A: It's designed for bulk, loose, or irregular materials including scrap steel, pig iron, slag, sand, gravel, crushed stone, coal, ore, and similar commodities. For highly abrasive materials (e.g., quartz, corundum), choose a grab with reinforced wear plating. For hot materials (molten metal, hot slag), specify a heat-resistant model.

Q3: How does the hydraulic system work?

A: The grab bucket is powered by an electric hydraulic station. When the hoist lifts, the hydraulic pump automatically engages, forcing the cylinders open or closed via the pendant control. No external power packs or additional operators are needed — the open/close cycle is controlled directly from the hoist pendant.

Q4: How do I maintain the grab bucket?

A: Regular checks include: inspecting hydraulic hoses and cylinder seals for wear or leaks (monthly), lubricating pivot bearings and pins (weekly), checking tooth wear and replacing cutting edges as needed, and inspecting structural welds and bolts for cracks (quarterly). Keep the interior of the petals clear of debris that could affect closing.

Q5: Can it be used with any electric hoist?

A: Most multi-petal grab buckets mount directly to standard hook-mounted hoists. However, you need to ensure: (1) the hoist's lifting capacity exceeds the grab bucket's total weight (material + grab mechanism), and (2) the hydraulic power unit is compatible with your hoist's power supply (voltage and phase). Always verify with the manufacturer before ordering to ensure proper pairing.
