Shanghai ENJUE Machinery Equipment Co., Ltd is one of the most experienced manufacturers and suppliers of electro hydraulic clamshell grabs in China. If you're going to buy custom electro hydraulic clamshell grabs made in China, welcome to get more information from our factory. For price consultation, contact us.
Enjue electro- hydraulic clamshell grabs are an intelligent loading and unloading device that integrates a motor, a hydraulic pump, and a hydraulic control system. Electro-hydraulic clamshell grabs are driven by an external power source to open and close the grab. It is designed for efficient grabbing and handling of bulk cargo, waste, and special materials. Its core advantage is that it combines the accuracy of hydraulic power and electric control, and can achieve 24-hour continuous operation under harsh working conditions, significantly improving material handling efficiency.
Hydraulic system innovation
Electro-hydraulic clamshell grabs constant power pump and servo control: Utilize an intelligent constant power hydraulic pump, which adjusts output flow in real-time through pressure feedback to prevent overflow loss. For example, ENJUE's grab bucket reduces flow at maximum pressure, reduces energy consumption, and stably controls oil temperature below 65°C, supporting long-term continuous operation.
Pressure-maintaining closed-loop control: Integrated pressure sensor and servo motor, automatically enters pressure-maintaining state when grab bucket reaches set pressure, shortens action response time to 0.3 seconds, and reduces energy consumption

Clamshell Optimization - Bionic Jaw Profile Design
The jaw flap profile is engineered using a bionic design philosophy, meticulously modeled after the flow characteristics of bulk cargo. This biomimetic curve ensures:
Significantly higher fill rates - material flows naturally into the grab cavity with minimal spillage.
Drastically reduced residual rates - especially when handling challenging materials such as coal fines, mineral powder, and other loose bulk commodities.
By matching the grab geometry to the rheological behavior of the cargo, every cycle delivers maximum payload with minimum waste.
Special configuration of electro-hydraulic clamshell grabs options:
Explosion-proof motor: suitable for the coal chemical industry and dusty environment (ExdIIBT4 certification).
Corrosion-resistant coating: for the offshore environment, epoxy glass flake coating is used, resistant to salt spray for 720 hours.
Low-temperature kit: -40℃ environmental startup guarantee, hydraulic oil heater, and low-temperature grease combination.
With its high efficiency, intelligence, and durability, the electro-hydraulic clamshell grabs have become the core equipment for material handling in the fields of ports, infrastructure, environmental protection, etc. Through continuous technological innovation and customized services, the product is constantly expanding its application boundaries and providing high-quality solutions made in China for global industrial material handling.
