Electric Hydraulic Grabs: Core Equipment for Efficient Material Handling

2025-06-17

In modern industry, material handling is vital for production. Among various equipment, Electric Hydraulic Grabsstand out as core solutions. They are key at port terminals for bulk cargo, in mines, waste treatment centers, steel and thermal power plants. Grabs like the Clamshell Grab, with its unique structure, boost efficiency, cut labor, and ensure safety through high - performance operation.

I. Parameter Details
Electric Hydraulic Grabs, integrating the best of Electrical and Hydraulic Grab technologies, have parameters that define their usage.Clamshell Grabs, a common type, typically have volumes from 1 to 20 cubic meters. Smaller ones (1-5m³) handle delicate tasks or light loads, like small port cargo. Larger Bulk Cargo Grabs (10-20m³) dominate in major mines and ports, capable of lifting multi-ton payloads in a single scoop.
The grab's force, a critical parameter, ranges from tens to hundreds of kilonewtons. Its magnitude depends on the material type: lower forces (e.g., for coal and grain) suffice for soft, low-density materials, while higher forces are essential for dense, hard substances like iron ore and stones to ensure secure grasping and transportation.
Electrical grabs offer diverse operating voltage options like 380V and 440V for different power setups. Motor power ranges from 15kW to 100kW, directly influencing work efficiency. With an opening/closing time of 10-30 seconds, shorter cycles enable more operations per unit time, boosting loading/unloading speed. Remote Control Grabs excel here, allowing precise timing control from afar.
Parameter Name Common Value Range Description
Specification (Volume) 1 m³ - 20 m³ Small volumes suit delicate or low - volume material operations; large volumes handle massive materials, grabbing and transporting several to dozens of tons at a time.
Grabbing Force Tens to hundreds of kilonewtons (kN) Adjusted according to material density and texture. Low - density, soft materials require less force, while high - density, hard materials need greater force.
Operating Voltage 380V, 440V, etc. Adapts to different power supply environments.
Motor Power 15kW - 100kW Determines the grab's work efficiency and power output. Higher power means stronger driving force and higher efficiency.
Opening/Closing Time 10 - 30 seconds Shorter cycle times allow more operation cycles per unit time, improving loading and unloading efficiency.
II. Remarkable Features
Electric Hydraulic Grabs and Remote Control Grabs stand out for their efficiency and energy savings. Their advanced hydraulic and intelligent control systems enable up to 30% energy reduction compared to traditional mechanical grabs. These grabs automatically adapt grabbing force and speed to material weight and resistance, optimizing energy use.
Secondly, electric hydraulic grabs ensure flexible operation. Clamshell and Remote Control Grabs rotate 360°, adapting seamlessly to confined spaces and diverse material handling scenarios. The Remote Control Grab allows operators to manage operations from a safe distance, optimizing both safety and convenience.
With high versatility and adaptability, Electric Hydraulic Grabs and Bulk Cargo Grabs can handle diverse materials by swapping jaws and accessories. They efficiently grab granular substances like coal and ore, blocky items such as stones and scrap steel, as well as loose waste, catering to various industries and working conditions.
In addition, Electric Hydraulic Grab have excellent sealing performance. When grabbing materials with high dust content or those prone to scattering, they can effectively prevent material spillage and dust dispersion, reducing environmental pollution and conforming to the requirements of green production in modern industries.

III. Exceptional Performance
In terms of performance, Electric Hydraulic Grabs excel. Crafted from high-strength alloy steel with an optimized design, they offer superior strength and wear resistance. Capable of enduring heavy-duty, repetitive operations and tough environments, their 5-10 year lifespan cuts down on replacement and maintenance costs, a benefit also shared by Clamshell and Bulk Cargo Grabs.
The grabs' hydraulic system is meticulously designed and optimized for stable pressure and rapid response. It delivers a robust, consistent grip, enabling reliable material handling across diverse conditions. Whether in extreme temperatures or high humidity, Electric Hydraulic Grabs maintain stable performance, ensuring uninterrupted operations.
In terms of safety, Electric Hydraulic Grabs, like Remote Control Grabs, feature robust safety systems. Overload protection automatically cuts power during overloads, preventing equipment damage and accidents. Limit protection controls the grab's opening and closing strokes precisely, avoiding malfunctions. In emergencies such as wire rope breakage, anti - fall protection locks the grab instantly, ensuring operator and equipment safety.
