Single Rope Mechanical Grab

Single Rope Mechanical Grab | Superior Reliability

Engineered for Rugged Bulk Handling in Critical Environments

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Bulk material handling in ports, coal yards, grain silos, mining, and industrial facilities requiring simple, reliable mechanical Grabs for loading/unloading operations of coal, ore, gravel, and grain.

Product Overview

Hengkun Crane’s Single Rope Mechanical Grab is a robust, mechanical operated gripping device designed for  material handling in demanding environments. Utilizing a single hoist rope system, this grab relies on mechanical linkage triggered by rope tension changes. Built for durability and low maintenance, it is ideal for rugged environments where simplicity and reliability are critical. Ideal for cranes, gantries, or monorail systems, it streamlines the handling of bulk materials.

Key Features & Benefits

1. Mechanical Design

   • The single rope design eliminates complex control systems and can be mechanically opened/closed during the lifting process.

   • The whole machine is easy to use and disassemble, suitable for underwater and land operations.

2. Heavy-Duty Construction

   • High-strength steel jaws with replaceable wear-resistant liners (Hardox® or manganese steel).

   • Reinforced pivot points and hinges (ISO 4301/FEM standards).

3. Low Maintenance

   • Minimal moving parts reduce wear and servicing requirements.

   • Self-lubricating bearings and corrosion-resistant coatings (ISO 12944 C4).

4. Safety Architecture
