Single Rope Touchdown Grab Bucket Manufacturers

APR Bright Industries is a leading manufacturer of single rope touchdown grab buckets. Our mechanical grab bucket are ideal choice for single-drum cranes, where external power is not available. Designed for superior penetration to handle iron ore, soda ash, coal, sand, and bulk grans without leakage. Our touchdown grabs functions with self-locking and self-unloading mechanism to ensure the bulk handling under the precise control of the crane operator.

Operational Mechanics (How it Works)


APR Bright Industries utilizes a reliable mechanical locking system that operate in four stages.

Placement: Touchdown grabs is lowered in the open position onto the material heap.
Engagement: Once grab touch the ground, further lowering of the crane hook slackens the wire rope, and causing the internal locking lever to shift into closing state.
Hoisting & Digging: Further as the hook is raised, the grabs jaws closes automatically and grabs the material with high closing force.
Discharge: When filled grabs lowered onto the discharge point (hopper or ground). and slackens again, mechanism reset , and upon hoisting grabs open itself to release the material.

Touchdown & Single-Line Grab: FAQ

Touchdown grabs are purely mechanical, making them a simpler and more cost-effective choice for operators. They are ideal for applications where material is consistently discharged onto a heap or into a hopper. Most importantly, they require zero electricity and involve zero battery maintenance, reducing long-term operational overhead.
We provide fully customized grab solutions for bulk material handling with capacities of up to 6CBM. Our engineering team designs the bucket geometry to match the specific material density and the lifting capacity of your crane.
Absolutely. For maritime operations, we use marine-grade galvanized wire ropes and specialized corrosion-resistant coatings. This ensures the grab maintains long-term reliability during ship-to-shore unloading, deck crane operations, and exposure to salt spray.
The opening and closing mechanism of our single-cable grab bucket is designed to handle the loading and unloading process automatically. Through the touchdown principle, the bucket manages the cycle efficiently by itself, making it an excellent “set-and-forget” solution for bulk commodities.
