STARK’s CROC GRIP belt clamps provide trusted, rated holding of conveyor belts during maintenance and splicing. The patented design delivers gripping force that exceeds conventional clamping solutions, and units can be linked in tandem to generate as much as 16 tonnes (35,270 lb) of pulling force. Built from high-grade steel with a lightweight, modular design, they’re easy to transport and assemble on site — bolts and handle stay assembled to minimise loss during transport.
| Model | W.L.L. | Total clamp force on belt | Force at belt creep | Typical applications |
|---|---|---|---|---|
| Mark 3 | 3 t (6,600 lb) | 4 t | 6 t | Quarries, brickworks, concrete plants, recycling |
| Mark 5 | 5 t (11,000 lb) | 6 t | 10 t | Steelworks, iron ore, coal, gold mines |
| Mark 7 | 7 t (15,400 lb) | 7 t | 14 t | Heavy-duty wide conveyors: power stations, steelworks, coal mines |
All W.L.L. ratings carry a 2:1 safety factor. Torque to rated force: Mark 3 — 50 Nm on the handle; Mark 5 — 90 Nm; Mark 7 — 160 Nm on a 300 mm spanner.
Match the W.L.L. to the tension your belt system generates during maintenance: Mark 3 for light-duty plants, Mark 5 for typical hard-rock and coal mines, Mark 7 for wide heavy-duty conveyors. We can confirm sizing from your belt spec.
Yes — linked in tandem, CROC GRIP units generate as much as 16 tonnes of pulling force.
