Calf Puller with Tension Limiter

Product Name Calf Puller with Tension Limiter
Product Image calf puller with tension limiter
Product Overview Calf Puller with Tension Limiter is a professional bovine obstetric instrument designed to assist controlled extraction during difficult calving procedures. The integrated traction-control mechanism helps prevent excessive pulling force by limiting the load applied through the operating handle.

The equipment is suitable for dairy farms, beef cattle operations, breeding farms, veterinary practices, and livestock production projects where controlled mechanical assistance may be required during calf delivery.
Key Features • Adjustable tension-limiting mechanism helps control traction during assisted calving.
• Operating lever locks when the preset traction level is reached.
• Two rope hooks help distribute traction more evenly between the calf's limbs.
• Quick-release mechanism allows rapid release even when the system is under load.
• Ratchet mechanism can rotate around the main tube for flexible working positions.
• Lightweight mechanism helps improve handling during farm and veterinary use.
• Long support frame provides leverage and controlled mechanical assistance during delivery.
Structural Components The calf puller generally consists of a long support tube, pelvic or rear support frame, aluminium ratchet mechanism, operating handle, adjustable tension limiter, rope attachment hooks, quick-release system, and compatible calving ropes.

The frame provides stable support against the cow, while the ratchet mechanism advances along the tube to generate controlled traction during the delivery process.
Working Principle / Structural Principle Calving ropes are positioned and attached to the puller's dual hooks according to proper veterinary obstetric practice. The support frame is positioned against the cow, and the operator moves the ratchet handle to apply gradual traction.

The adjustable tension-control system limits the applied pulling force. When the preset level is reached, the operating handle locks, helping prevent uncontrolled increases in traction. The mechanism can be repositioned around the support tube to accommodate different extraction angles. :contentReference[oaicite:0]{index=0}

Applications Calf Puller with Tension Limiter is suitable for controlled assistance during difficult bovine births under appropriate veterinary or experienced livestock-management supervision.

Typical applications include dairy farms, beef cattle farms, breeding stations, veterinary clinics, livestock hospitals, ranches, agricultural projects, and emergency calving equipment inventories.
Customization Options SHEWUYOU can provide different frame widths, support structures, rope configurations, accessory combinations, packaging methods, and bulk purchasing solutions according to project requirements.

OEM supply options are available for livestock equipment distributors, veterinary suppliers, cattle farm groups, engineering companies, and agricultural project purchasers.
Installation & Maintenance Before use, assemble the support frame and traction mechanism according to the selected configuration and verify that the ratchet, tension limiter, quick-release system, hooks, and calving ropes operate correctly.

After each use, clean and disinfect components exposed to biological material. Inspect the support tube, frame, rope hooks, ratchet teeth, tension-control mechanism, and ropes for deformation, wear, corrosion, or damage before storage.
Project Cases Suitable for commercial dairy operations, beef cattle farms, breeding centers, veterinary service teams, livestock health programs, cattle farm construction projects, and distributors requiring professional bovine obstetric equipment.
Product FAQ Q: What is the purpose of the tension limiter?
A: The tension limiter helps prevent excessive pulling force during assisted calving. When the selected force is reached, the operating mechanism limits further traction through the handle.

Q: Why are two rope hooks used?
A: Two hooks allow both calving ropes to be attached separately, helping distribute traction more evenly during extraction.

Q: Can the mechanism work from different angles?
A: Yes. Certain configurations allow the mechanism to rotate 360 degrees around the support tube for flexible positioning.

Q: Is a calf puller intended to replace veterinary judgment?
A: No. Difficult births should be assessed carefully, and the equipment should be operated by trained personnel following appropriate animal welfare and veterinary obstetric practices.

Q: Can different configurations be supplied?
A: Yes. Frame dimensions, accessories, rope sets, packaging, and purchasing quantities can be supplied according to project requirements.
