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.
Frequently Asked Question
Q: Why use a Touchdown Grab instead of a Remote Control Grab?
Ans: Touchdown grabs are quite simple, mechanical , and more cost-effective for operators where material is always discharge onto a heap or into a hopper. It is required zero electricity and zero battery maintenance.
Q: What is the maximum material density these grabs can handle?
Ans: We provide customized grabs solution for material handling up to 6CBM.
Q: Are your grabs compatible with marine/sea environments?
Ans: Yes. We use marine-grade galvanized wire ropes and corrosion-resistant coatings, ensure the long-term reliability for ship-to-shore unloading and deck cranes operation.
Q: How Single Line Clamshell Buckets for Bulk Commodities work?
Ans: Opening and closing mechanism for single-cable grab bucket easily handle the process of loading and unloading of material itself. Our touchdown grab bucket is enough efficient to handle the process by itself.
