Crawler-Type Pulling Machine for FRP Rock Bolts — Designed for Continuous Pultrusion
This Crawler-Type Pulling Machine for FRP Rock Bolts is specialized equipment designed for the continuous pultrusion of FRP (Fiber-Reinforced Polymer) rock bolts—including GFRP and fiberglass-reinforced plastic rods—and other composite rod profiles. The machine grips the product between upper and lower crawler tracks and applies steady, continuous traction to pull the FRP product out of the mold and heating zone, meeting production requirements for various specifications of FRP rock bolts.
Compared to standard short-frame haul-off units, our machine features a 3.5-meter-long traction frame, providing a longer effective traction span. The extended track length increases the contact area between the product and the rubber gripping pads, thereby enhancing stability during the haul-off process; this is particularly advantageous for products requiring high traction forces, such as FRP rock bolts and ribbed FRP rods.
3.5-Meter Traction Frame for Enhanced Stability
The machine utilizes a 3.5-meter-long traction frame, offering a significantly longer effective clamping and traction zone compared to conventional short-frame crawler haul-off units.
FRP rock bolts often feature high resin content and complex surface profiles—such as threads, embossed patterns, or specialized structures—placing high demands on the clamping force and stability of the haul-off equipment.
The extended frame increases the contact length between the product and the crawler tracks, ensuring more consistent traction. This minimizes slippage and improves operational stability during the continuous production of FRP rock bolts.
Driven by 2 Sets 2.2kW High-Torque Motor and Gear Reducer
Stable and continuous traction is essential for FRP rock bolt production, making the drive system a critical component of the haul-off machine.
This machine employs a 2.2kW high-torque motor paired with a gear reducer to drive the crawler tracks. The reduction mechanism boosts output torque, enabling the equipment to maintain substantial traction capabilities even at lower operating speeds. Compared to designs that prioritize motor power alone, a high-torque, gear-reduced drive system is better suited for composite material production equipment—such as that used for FRP rock bolts—which requires low speeds, high traction force, and continuous operation.
Furthermore, the motor, gearbox, and control system can be configured to meet specific customer requirements regarding product specifications, production speed, and traction force.
Wear-resistant rubber pads for FRP product traction
The rubber pads on the caterpillar haul-off unit come into direct contact with the FRP product; therefore, their wear resistance, gripping force, and ability to conform to the product surface directly impact the equipment’s service life and traction performance.
This machine utilizes wear-resistant rubber pads as the gripping elements; this design ensures effective frictional traction while minimizing pad wear during long-term, continuous production.
For products such as FRP rock bolts, GFRP rebar, and FRP pultruded rods, custom rubber gripping pads can be designed to match the specific product diameter and surface structure, ensuring stable gripping and traction.
Suitable for a wide range of FRP pultruded products
The caterpillar haul-off unit for FRP rock bolts is not limited to rock bolt production; depending on the specific process, it can also be used for:
FRP rock bolts, GFRP rock bolts, glass fiber reinforced plastic rebar, FRP pultruded rods, FRP round rods, composite rods, and other continuous pultruded products.
Configurations regarding track width, rubber pad structure, clamping mechanism, motor/gearbox assembly, and control systems can be tailored to the product’s diameter, surface structure, production speed, and required traction force.
Why do FRP rock bolts require a high-torque caterpillar haul-off unit?
FRP rock bolts are typically manufactured using a continuous pultrusion process; once the resin has cured, the product must be continuously pulled from the production line by a haul-off unit.
Insufficient traction force can lead to issues such as product slippage, unstable hauling speeds, or limitations on production speed. Therefore, a reliable haul-off machine for FRP rock bolts requires:
Sufficient pulling force, stable gripping capability, wear-resistant rubber track pads, and a reliable gear-reduction drive system.
Our caterpillar haul-off machine for FRP rock bolts utilizes a combination of a 3.5-meter-long traction frame, a 2.2 kW high-torque gear motor, and wear-resistant rubber pads to provide a stable pulling solution for the continuous pultrusion production of FRP rock bolts.
