Centered on "heavy-load safety + full-function integration + labor-saving efficiency", the YD30-004 5-Ton Multi-Purpose Cable Puller is optimized to address the pain points of traditional pullers, such as "difficult heavy-load operation, single function, and poor environmental adaptability". Its core highlights are as follows:
- Double Ratchet Braking: The two-way ratchet wheels engage with pawls—preventing the load from sliding down during lifting and controlling speed precision during lowering. Even if the handle is accidentally released, the braking system locks within 0.3 seconds, keeping the 5-ton heavy object suspended stably without displacement. The safety factor is doubled compared to the single ratchet design;
- Overload Protection: Equipped with a mechanical overload protection mechanism. When the load exceeds 20% of the rated value (i.e., 6000kg), the gear set automatically disengages, and the handle idles without applying force—preventing steel cable breakage due to overload or deformation of the main structure, and eliminating safety accidents from the source.
The hook adopts a "pin + latch double-safety" design: the pin locks the hook opening after insertion to prevent the heavy object from disengaging due to shaking; the latch covers the top of the pin to avoid accidental ejection during operation. In the scenario of 牵引 ing a 4.5-ton truck, even if the vehicle shakes violently, the hook can firmly lock the lifting lug without disengagement risk.
- Lifting + Lowering: The 15:1 transmission ratio combined with the tooth-by-tooth lowering design allows accurate lowering of a 5-ton motor to the installation base with a deviation ≤5mm, replacing the traditional combination of crane + manual crowbar;
- Traction + Tensioning: The 7.85KN traction force can easily pull a 4.5-ton trapped vehicle, and is also suitable for tensioning 300-meter fence wires on farms. It replaces the traction rope + manual tensioner, improving operation efficiency by 4 times.
- 15:1 Transmission Ratio: Amplifies the operating force by 15 times. Taking a 5-ton heavy object as an example, the theoretical operating force is only 333N (approx. 34kg), which can be achieved by one person with one hand. It is 56% more labor-saving than ordinary pullers with a 6:1 transmission ratio;
- Extended Handle: The 420mm extended handle + 40mm-diameter anti-slip rubber grip increases the palm contact area by 80%. After 60 minutes of continuous operation, the palm soreness is reduced by 90% compared to traditional handles—solving the pain points of "hand soreness and laboriousness" in heavy-load operations.
- Main Steel Plate: 5mm-thick Q345 steel plate formed by integral bending, with 4 reinforcing ribs on the cabinet load-bearing frame. The cabinet deformation is ≤1.5mm when fully loaded with 5 tons, far exceeding industrial safety standards;
- Drop-Forged Hook: The 45# drop-forged steel hook is quenched and tempered, with no deformation when hit by a 1500kg 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 + galvanization" double layers, and the steel cable is galvanized—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 3 years longer than that of ordinary pullers without protection.
Scenario Requirement: A heavy auto repair shop needs to handle the rescue of 4.5-ton trapped trucks and the positioning of 5-ton CNC lathes. The workshop has limited space and lacks large overhead cranes. The tool needs to have strong traction, safe operation, and adapt to oily environments.
Operation Process:
- Trapped Vehicle Rescue: 2 people carry the puller to the trapped vehicle, hang one hook on the anchor point of the workshop load-bearing column, and connect the other end to the truck chassis via a D-type shackle; with the 15:1 transmission ratio, one person can rotate the handle to complete the trapped vehicle rescue in 10 minutes, and the double-safety hook has no disengagement risk;
- Equipment Positioning: Connect the 5-ton CNC lathe to the puller via a lifting ring, 2 people cooperate to lift the equipment and slowly move it to the embedded track; fine-tune the position through the double ratchet tooth-by-tooth lowering function, and finally achieve a positioning deviation ≤3mm, meeting the installation precision requirements;
- Post-Operation Maintenance: Wipe the oil stains on the puller surface with a rag. The spray coating has no residual stains, and it can be stored in the tool cabinet directly, remaining smooth for the next use;
Result: With heavy-load traction and precise positioning, compared with the traditional "hydraulic jack + manual cart" combination, it improves efficiency by 90%, no large equipment is needed, saving workshop space and equipment purchase costs.
Scenario Requirement: A farm needs to handle the handling of a 3.8-ton tractor to the warehouse and the construction of a 200-meter heavy fence (requiring wire tensioning). The farm has an open area but lacks electricity. The tool needs to be portable, have a tensioning function, and adapt to the humid field environment.
Operation Process:
- Agricultural Machinery Handling: 2 people fix the puller on the warehouse load-bearing beam, connect the hook to the tractor lifting lug, and complete the lifting and handling of the 3.8-ton agricultural machinery in 20 minutes with the 15:1 transmission ratio. The double ratchet braking ensures stable suspension of the equipment;
- 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 7.85KN tension ensures uniform wire tension, improving the fence flatness by 95% and replacing the traditional manual tensioner;
- Environmental Adaptation: After rainy-day operations, wipe the rainwater on the puller surface with a dry cloth. The double anti-corrosion treatment prevents rust, and it can be stored in the farm warehouse directly;
Result: With multi-function and anti-corrosion design, the agricultural machinery handling efficiency is increased by 85%, the fence construction time is shortened from 3 days to 1 day, adapting to the farm scenario without electricity.
Scenario Requirement: A construction site needs to install a 4-ton steel structure onto a 10-meter-high scaffolding. There is no large lifting equipment on-site. The tool needs to be lightweight, safe for lifting, and adapt to the outdoor dusty environment.
Operation Process:
- High-Altitude Preparation: 2 workers carry the puller to the 10-meter scaffolding, hang the hook on the scaffolding load-bearing crossbar (load ≥8 tons), and connect the lower hook to the steel structure via a lifting ring;
- Lifting Operation: With the 15:1 transmission ratio, 2 people cooperate to rotate the handle to lift the steel structure at a speed of approx. 0.8m/min. The double ratchet braking ensures stable lifting without shaking;
- Precise Installation: After reaching the installation height, fine-tune the position of the steel structure through the tooth-by-tooth lowering function to accurately align with the bolt holes (deviation ≤5mm) and complete the installation;
Result: With high-altitude safe lifting and precise control, the steel structure installation efficiency is increased by 80%, no equipment falling risk, adapting to the dusty environment of construction sites.
A1: One person can operate it easily, with the actual operating force only approx. 34kg. The product adopts a 15:1 high transmission ratio design, amplifying the operating force by 15 times. According to mechanical calculations, the theoretical operating force for a 5-ton heavy object = 5000kg ÷ 15 ≈ 333N (approx. 34kg), which is equivalent to lifting a 34kg bucket. Ordinary adults can easily complete the operation. In actual tests, a female user weighing 55kg can rotate the handle continuously 25 times without obvious fatigue, fully meeting the needs of single-person heavy-load operation.
A2: The braking system works normally in low-temperature environments with no failure risk.
- Material Adaptation: The ratchet/pawl is made of SUJ2 high-carbon chromium bearing steel, maintaining a hardness of HRC 58-62 at low temperatures (-30℃) with no brittleness risk; the brake spring is made of low-temperature special alloy spring, with no elastic coefficient attenuation at -30℃, ensuring tight engagement between the pawl and ratchet;
- Actual Testing: After the product is left in a -30℃ low-temperature environment for 24 hours, it immediately undergoes 5-ton load lifting/lowering tests. The braking response time is still ≤0.3 seconds, and the load remains suspended stably without sliding—fully meeting the needs of outdoor operations in northern winter.
A3: There is no mandatory minimum order quantity for customization, and customization does not affect load performance.
- Customization Conditions: Note "12m 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;
- Performance Assurance: The customized steel cable is consistent with the standard model in material (diameter ≥10mm, breaking force ≥32KN). A 5-ton load test is conducted before leaving the factory to ensure no attenuation in traction and lifting performance;
- Cycle Difference: The delivery cycle for standard models is 15-18 days, and the customized steel cable model requires an additional 4-6 days (including steel cable cutting, assembly, and testing). The manufacturer will provide real-time production progress feedback, which does not affect the operation plan.
A4: Judge the replacement need by the number of broken wires, and the replacement process is simple.
- Replacement Judgment: According to GB/T 5972-2016 "Crane Wire Rope Maintenance, Inspection and Discard", when the number of broken wires in one lay length of the steel cable is ≥6 (for 10mm-diameter steel cable), or the wear amount is ≥10% of the diameter (i.e., ≤9mm), immediate replacement is required;
- Replacement Steps: ① Turn off the puller's freewheel and loosen the hook fixing bolt; ② Remove the old steel cable and fix one end of the new steel cable to the puller drum; ③ Turn on the freewheel and slowly rotate the handle to wind the steel cable onto the drum; ④ Fix the hook bolt to complete the replacement. It can be completed by one person in 30 minutes without professional tools.
