Our double rope mechanical grab consists of two wire ropes, a well‑proven pulley system, and grab buckets. It features no other power required, so it will not malfunction in humid or dusty conditions.

If your operation handles coal, ore, sand, grain, or other bulk materials, you may well know: the bottleneck is often not the crane, but the lifting attachment. The grab is purpose‑built for exactly this task - higher payload retention, less material spillage, and greater stability.

We can customize special grabs working load ranges from 10 t to 80 t. Structural certification complies with FEM 9.511 M8 class, and safety compliance meets EN 13155 Class II.

Sequence of operation:

• Positioning: Both ropes lower simultaneously, and the grab lands on the material pile in open condition.
• Digging & Grabbing: The closing rope is tensioned. The jaws rotate inwards to dig into the material. The reduced centre‑to‑centre distance of pulleys forces the jaws to close.
• Lifting: Both ropes hoist upwards together. The loaded grab travels to the discharge point.
• Discharging: The supporting rope remains taut while the closing rope is slackened. The lower beam opens the jaws by its own weight to release materials.

This completes one full operating cycle of the grabs. When paired with well‑matched equipment, a full cycle can be finished in as fast as around 6 seconds, depending on grab capacity.

Grabs operate daily amid dust, grit, moisture, and impact. Our double rope mechanical grabs are engineered specifically for these harsh conditions.

Intermeshing Jaw Closure - not merely closed, but sealed. The jaw profiles overlap one another to prevent fine‑material spillage during lifting. Our tests demonstrate a filling rate up to 90 %, with material loss below 2 % throughout transportation.

Replaceable Wear Liners - high‑stress zones inside the jaws are protected by bolt‑on liners. When liners wear out, only the liners need replacing instead of the entire grab body. This feature alone triples the major‑overhaul interval.

Sealed Hinge Points - grease channels lead to every pin and bush. Daily visual inspection plus weekly lubrication covers all routine maintenance.
