Product Introduction

YONGHANG supplies Haul-off belts for all types of extruders, including caterpillar haul-off for cables, wires, pipes and profiles.

Haul-offs” are pulley-driven parallel belts that contact opposite sides of in-process products, usually by means of rollers exerting suitable pressure for the belts to grip and haul them, with the desired controlled pulling action.

Our range includes specific combination of base belts, tensile strengths and fabrication details to meet technical requirements of variety of extrusion applications, including specific resistance, hardness, temperature, friction needs.

FAQ of yonghang haul off belts

For more information about haul off belts, if you can’t find your answer below, feel free to contact our online customer service team or send us an email. We’re happy to assist you. For pricing inquiries, please reach out to our sales team anytime.

EPDM high-temperature rubber is the preferred choice in the following scenarios: If your haul-off belt requires long-term operation in high-temperature environments (e.g., exceeding 105°C) or is primarily used outdoors where it must withstand prolonged exposure to sunlight, rain, and ozone erosion, EPDM offers greater reliability.
Preferred scenarios for TPU: If your application prioritizes the belt’s mechanical strength, durability, and abrasion resistance—such as in high-tension or high-friction conditions—TPU delivers extended service life. Additionally, if your production process demands high efficiency, low scrap rates, and material recyclability, TPU’s thermoplastic processing characteristics offer significant advantages. For further details, consult our sales manager for tailored selection recommendations.

Yes. We provide food-grade polyurethane or silicone belts compliant with FDA or EU standards, and can supply relevant certification documents to ensure your production safety.

Most Common General Purpose: CR rubber & EPDM
Oil-Contaminated Environments: Nitrile rubber
High-Temperature Environments: Silicone rubber
Food Industry: Food-grade polyurethane or silicone rubber

This is typically caused by insufficient friction or tension. We recommend selecting materials with higher friction coefficients (e.g., patterned PU or EPDM) and inspecting the tensioning system for proper function.

poly-V belts：PJ PK PL PM
Timing belt：T2.5 T5 T10 AT5 AT10 3M 5M 8M RPP etc.
Falt belt:PU plastic, nylon, rubber
Variable Speed belt
Joined v-belt
All of the above can be used as the transmission type of “haul off belts”. Various wear-resistant coatings of different materials are added on the surface, such as TPU, EPDM, CR rubber, PVC, silicone, etc.

We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping also optional.

We conduct R&D in China first. The Yonghang brand is particularly popular in China. We have collaborated with many well-known domestic companies such as Rifeng and Liansu to develop numerous models of haul off belts. These belts perform exceptionally well when used on pipe, wire, and cable extrusion machines.

A simple method is the “finger-press test”: Press the belt between two rollers; it should exhibit moderate elasticity (typically depressing 1-2 cm). The most accurate method is to measure with a tension gauge.

Of course. All our products undergo 100% factory inspection before shipment to customers. We conduct visual inspections, hardness tests, tensile tests, dimensional measurements, and a series of other checks. We have 5 QC staff members, and we also hold a monthly company-wide quality feedback meeting.
