Centered on "full-function integration + full-scenario adaptation + labor-saving efficiency", the YD30-003 Multi-Purpose Cable Puller is optimized to address the pain points of traditional pullers, such as "single function, laborious operation, and limited scenarios". Its core highlights are as follows:
Adopting a double ratchet wheel braking system, the force is amplified through the 15:1 transmission ratio gear set during lifting, allowing one person to easily lift a 4.8-ton heavy object. During lowering, the speed is controlled tooth by tooth, with a minimum lowering amount ≤4mm. For example, in the scenario of factory motor installation, a 3-ton motor can be accurately lowered to the installation base with a deviation ≤5mm, avoiding equipment collision damage.
- Traction Function: The 6.8KN traction force can easily pull a 3.5-ton trapped vehicle. In the scenario of agricultural machinery rescue on farms, 2 people can complete the trapped vehicle rescue in 10 minutes without relying on large rescue equipment;
- Tensioning Function: It can be used for tensioning farm fence wires, camping tent ropes, and cables. Through the adjustment of steel cable tension, the fence wires are evenly tensioned and the tent is more stably set up. It replaces traditional manual tensioning tools, improving efficiency by 3 times.
Through the 15:1 transmission ratio design of the gear set, the operating force is amplified by 15 times. Taking a 4.8-ton heavy object as an example, the theoretical operating force is only 320N (approx. 32.6kg), which can be achieved by one person with one hand. It is 67% more labor-saving than ordinary pullers with a 5:1 transmission ratio, and even female users can easily complete heavy-load operations.
The handle length is extended to 400mm (longer force arm), and combined with the 38mm-diameter anti-slip rubber grip, the palm contact area is increased by 70%. After 50 minutes of continuous operation, the palm soreness is reduced by 85% compared with traditional handles, solving the pain points of "hand soreness and discomfort" during long-term outdoor operations.
- Main Steel Plate: 4.5mm-thick Q235 steel plate formed by integral bending, with 3 reinforcing ribs on the cabinet load-bearing frame. The cabinet deformation is ≤2mm when fully loaded with 4.8 tons, far exceeding industrial safety standards;
- Drop-Forged Hook: The 40Cr drop-forged steel hook is quenched and tempered, with no deformation when hit by a 1200kg heavy object. Even in accidental collisions in complex outdoor operation scenarios, it can ensure equipment safety.
The main body is protected by electrostatic spray coating + galvanized steel cable, providing double anti-corrosion protection. After operations in humid farm environments or outdoor rainy days, it can be restored to cleanliness by wiping with a dry cloth, with no rust risk. Its service life is 2 years longer than that of ordinary pullers without protection.
Scenario Requirement: A farm needs to handle the rescue of a 3.2-ton trapped tractor and the handling of a 4-ton grain dryer. The farm has an open area but lacks large equipment. The tool needs to be portable, have strong traction, and adapt to the humid field environment.
Operation Process:
- Trapped Vehicle Rescue: 2 people carry the puller to the trapped vehicle, hang one hook on the fixed ground anchor, and connect the other end to the tractor chassis via a shackle; with the 15:1 transmission ratio, one person can rotate the handle to pull the trapped vehicle, completing the rescue in 10 minutes;
- Equipment Handling: Connect the grain dryer (4 tons) to the puller hook via a lifting ring, 2 people cooperate to lift the equipment, slowly move it to the designated position. The double ratchet braking ensures stable suspension of the equipment with no sliding risk;
- Subsequent Maintenance: After the operation, wipe the mud on the puller surface with a dry cloth. The spray coating has no residual stains, and it can be stored in the warehouse directly, remaining smooth for the next use;
Result: With multi-function and portable design, compared with the traditional "jack + manual cart" combination, it improves operation efficiency by 80%, no large equipment is needed, saving the farm's equipment purchase cost.
Scenario Requirement: An outdoor camping team needs to set up a large camping tent (requiring tent rope tensioning), and a farm needs to build an 1.8-meter-high fence (requiring fence wire tensioning). The tool needs to be portable, have a tensioning function, and be usable in outdoor environments without power supply.
Operation Process:
- Tent Setup: Fix the puller's steel cable between the tent ground nail and the top pole, tension the rope by rotating the handle. The 15:1 transmission ratio ensures uniform rope tension, making the tent more stable and able to withstand level-5 winds without shaking;
- Fence Construction: Fix the puller on the fence post, connect the steel cable to the fence wire, rotate the handle to tension the wire. The 6.8KN tension ensures no slack in the wire, improving the fence flatness by 90%;
- Storage and Carrying: After the operation, retract the steel cable. The puller weighs only 20kg and can be placed in the trunk of a camping car without occupying too much space;
Result: With tensioning function and portability, the tent setup time is shortened from 2 hours to 40 minutes, and the fence construction efficiency is doubled, adapting to outdoor scenarios without power supply.
Scenario Requirement: A factory needs to install a 4.5-ton CNC milling machine. The narrow workshop space prevents the use of overhead cranes. The tool needs to accurately lift and lower the equipment, and adjust the equipment position (deviation ≤5mm).
Operation Process:
- Lifting Preparation: Fix the puller on the workshop load-bearing beam, connect the hook to the milling machine lifting lug, and activate the double ratchet braking system;
- Precise Operation: With the 15:1 transmission ratio, 2 people cooperate to lift the milling machine. After rising to the installation height, fine-tune the position through the tooth-by-tooth lowering function, and finally accurately position the milling machine on the embedded track (deviation ≤3mm);
- Installation and Fixing: Keep the puller in a load-bearing state after positioning, and fix the milling machine with gaskets to avoid equipment displacement during installation;
Result: With precise control and heavy-load capacity, the equipment installation efficiency is increased by 95%, the installation deviation rate is reduced to less than 0.3%, and no large equipment is needed—saving workshop space.
A1: One person can operate it easily, with guaranteed labor-saving performance. The product adopts a 15:1 high transmission ratio design, and the force is amplified through gear reduction. Theoretically, only 320N of operating force (approx. 32.6kg) is needed to pull a 4.8-ton heavy object, which is equivalent to lifting a 32kg heavy object. Ordinary adults can easily complete the operation. In actual tests, an adult weighing 60kg can rotate the handle continuously 30 times without obvious fatigue, fully meeting the needs of single-person operation.
A2: The double ratchet braking locks in both directions, with no slipping risk. The double ratchet wheels correspond to the load lifting and lowering directions respectively. During operation, braking is achieved through the engagement of pawls and ratchets: when lifting, one ratchet locks to prevent the load from sliding down; when lowering, the other ratchet engages tooth by tooth to control the load to lower slowly, with a minimum lowering amount ≤4mm. Even if an operation error occurs suddenly, the pawl will lock the ratchet immediately, keeping the load suspended stably without slipping. The safety factor is far higher than that of the single ratchet design.
A3: Cleaning and maintenance are simple, but long-term lack of maintenance will shorten the service life. The specific steps are as follows:
- Cleaning Method: Rinse the mud on the steel cable surface with a high-pressure water gun, then dry the water with a rag; for stubborn stains, wipe with a neutral detergent, avoiding the use of steel wool (to prevent scratching the galvanized layer on the steel cable surface);
- Maintenance Points: After cleaning, apply lithium-based grease on the steel cable surface (thickness 1-2mm), and maintain it once every 3 months (monthly maintenance is recommended for high-frequency outdoor use); if not maintained for a long time, impurities in the mud will accelerate the wear of the steel cable, and the service life may be shortened to 1/2 of the original.
A4: There is no mandatory minimum order quantity for customization, and the cycle is only extended by 3-5 days.
- Customization Conditions: Note "8m steel cable" when placing the order, no additional customization fee is required (single-unit customization is also supported); if a special material steel cable (e.g., stainless steel cable) is needed, confirm compatibility with the manufacturer in advance and only make up the material price difference;
- Cycle Difference: The delivery cycle for standard models is 12-15 days, and the customized steel cable model requires an additional 3-5 days (including steel cable cutting, assembly, and testing). The manufacturer will provide real-time production progress feedback, which does not affect the operation plan;
- Quality Assurance: The quality of the customized steel cable is consistent with that of the standard model, with a breaking force ≥28KN. Load performance testing can be conducted on-site during acceptance to ensure it meets the requirements.
