Centered on "heavy-load safety + easy operation + durability", the YD30-001 2-Ton Capacity Cable Puller is optimized to address the pain points of manual lifting tools such as "difficult load control, laborious operation, and easy wear". Compared with traditional cable pullers, it has significant advantages in control precision, portability, and durability. Its core highlights are as follows:
Adopts a "ratchet-pawl single-tooth engagement" design. When lowering or releasing the load, the cable length can be adjusted one notch at a time, with each adjustment corresponding to a load movement of ≤5mm. This completely avoids the risk of load collision caused by "free-fall" lowering in traditional designs. Even if an operation error occurs during high-altitude work, the braking system locks instantly, keeping the load suspended without sliding—meeting the high safety precision requirements of construction and equipment installation scenarios.
Equipped with a mechanical overload protection mechanism. When the load exceeds 25% of the rated value (i.e., 2500kg), the ratchet and pawl automatically disengage, and the handle cannot apply force further. This prevents cable breakage due to overload or deformation of the main structure. The protection device is triggered by mechanical structure without power supply, adapting to outdoor and high-altitude scenarios without power, and eliminating safety accidents from the source.
Equipped with a freewheel disengaging mechanism. When quick cable release is needed, simply toggle the freewheel switch to disengage the pawl from the ratchet, allowing manual quick cable pulling with a speed of 1m/10s. For example, in trapped vehicle traction scenarios, a 3m-long cable can be fully released in only 30 seconds—saving 70% of time compared to traditional designs without freewheel, and greatly improving emergency rescue and quick positioning efficiency.
With a net weight of only 3kg, it can be carried with one hand. Whether for high-altitude lifting of components on building exteriors, vehicle traction in auto repair shops, or shelf adjustment in warehouses, it can be easily transported to the operation point. The handle adopts an ergonomic rubber grip with anti-slip texture, ensuring no hand soreness even after 30 minutes of continuous operation—solving the pain points of "uncomfortable grip and slippage" of traditional metal handles.
The ratchet and pawl components adopt a "three-steel-plate stacked welding" structure instead of the traditional single-steel-plate design. The contact area is doubled, and wear resistance is improved by 50%. Tests show that after 5,000 consecutive operations under the rated load of 2000kg, the pawl wear is only 0.2mm—far lower than 0.8mm of traditional single-steel-plate designs. Service life is extended by 3 times, reducing the cost of frequent component replacement.
The main steel plate and cable are zinc-plated with a zinc layer thickness of ≥8μm, showing no rust after 48-hour salt spray test. It can be used for a long time in outdoor humid and rainy environments (e.g., open-air operations on construction sites, ship deck equipment fixing). The drop-forged steel hook has a hardness of HRC 35-40 after heat treatment, with no deformation or cracking even when hit by a 500kg heavy object—meeting the durability requirements of heavy industrial scenarios.
Scenario Requirement: An auto repair shop needs to configure manual lifting tools for 2 maintenance workstations, used for pulling trapped vehicles (approx. 1500kg light truck) and adjusting vehicle positions (e.g., moving accident vehicles to maintenance platforms). The tool needs to be portable, powerful in traction, and capable of precisely controlling vehicle movement distance (to avoid colliding with equipment).
Operation Process:
- Preparation: The technician carries the YD30-001 to the trapped vehicle, hangs one hook of the puller on the fixed anchor point in the workshop, and connects the other hook to the vehicle chassis lifting ring; toggles the freewheel switch to quickly release the 3m cable, and adjusts the puller position to the force-bearing straight line;
- Traction Operation: Turns off the freewheel, rotates the handle clockwise to drive the cable to retract, and the vehicle moves slowly; if fine position adjustment is needed, gently rotates the handle counterclockwise to move the vehicle millimeter by millimeter through single-tooth adjustment until it is accurately positioned on the maintenance platform;
- Post-Operation Storage: Releases the hooks, activates the freewheel to retract the cable, and places the puller in the tool cabinet—no additional handling tools are needed for the 3kg weight;
Result: With precise adjustment and portable design, compared with the traditional "jack + crowbar" combination, it improves vehicle positioning efficiency by 80%, eliminates the risk of vehicle collision, and reduces technicians' physical consumption by 65%.
Scenario Requirement: A construction site needs to configure lifting tools for the exterior wall construction team, used for lifting steel pipes and fasteners within 200kg (approx. 150kg per lift). The operation point is on a 10m-high scaffolding, requiring the tool to be lightweight, anti-drop safe, and adaptable to outdoor humid environments.
Operation Process:
- High-Altitude Preparation: The construction worker carries the puller up the scaffolding, hangs the hook on the scaffolding load-bearing crossbar (load-bearing ≥500kg), and connects the lower hook to the material basket (containing 150kg steel pipes);
- Lifting Control: Rotates the handle clockwise to lift the material at a speed of approx. 0.5m/min, and stops when reaching 10m height; if basket position adjustment is needed, gently rotates the handle counterclockwise to move the basket horizontally through single-tooth adjustment (≤5mm each time), avoiding collision with the scaffolding;
- Environment Adaptation: After rainy-day operations, wipes the puller surface with a dry cloth. The zinc-plated material has no rust and remains smooth for next use;
Result: With anti-drop safety and rust-proof design, high-altitude lifting efficiency is increased by 70%, no risk of material falling, and service life reaches more than 3 years in outdoor humid environments.
Scenario Requirement: A factory workshop needs to install an 800kg machine tool, requiring traction of the machine tool from the ground to the embedded track (deviation ≤10mm). The narrow workshop space prevents the use of large lifting equipment, requiring manual tools for precise traction and stable fixing.
Operation Process:
- Traction Preparation: Fixes the puller to the workshop wall anchor point, connects the hook to the machine tool side lifting lug, activates the freewheel to release the cable to the appropriate length, and turns off the freewheel;
- Precise Traction: Two people cooperate to rotate the handle, and the machine tool moves slowly toward the track. Pauses every 50mm of movement, and corrects the deviation through single-tooth adjustment; finally, accurately positions the machine tool on the track (deviation ≤5mm), meeting the installation precision requirements;
- Temporary Fixing: Maintains the puller in a force-bearing state after positioning, and fixes the machine tool with gaskets to avoid displacement during installation;
Result: With precise adjustment and heavy-load traction, equipment positioning efficiency is increased by 90%, installation deviation rate is reduced to less than 0.5%, and no large equipment is needed—saving workshop space.
A1: Overload use is not recommended, as it will trigger the protection device and pose safety risks. The product's rated load of 2000kg is a strictly tested safe value. The built-in overload protection device will automatically lock when the load exceeds 2500kg, preventing the handle from applying force and avoiding immediate damage. However, long-term overload (e.g., 2200-2400kg) will cause cable fatigue and accelerated pawl wear—for example, if the cable bears 2200kg load for a long time, its breaking force will decrease from 12000N to 10000N, increasing the breakage risk by 40%. At the same time, the wear of the ratchet component will double, and the service life will be shortened to 1/3 of the original.
A2: No loss of control will occur, as the freewheel is designed with a buffer mechanism. The freewheel only functions to "disengage pawl-ratchet engagement"; cable release still requires manual traction, rather than "free fall" release. For example, when pulling a 3m cable, the cable end needs to be pulled at a constant speed by hand, with the speed controlled manually—no sudden acceleration or swinging. If you let go, the cable will slowly sag due to its own weight (speed ≤0.2m/s) with no swinging risk. Meanwhile, the freewheel switch has a "gear locking" design, which will not open accidentally due to vibration—further ensuring safety.
A3: Regular cleaning and maintenance can prevent rust, and slight rust can be repaired.
- Daily Maintenance: After each outdoor use, wipe the surface moisture of the main body and cable with a dry cloth; apply anti-rust oil (lithium-based grease is recommended) once a month, focusing on the ratchet-pawl engagement area and cable; if it rains, clean and maintain immediately after use to avoid rainwater residue causing zinc layer corrosion;
- Rust Repair: If slight rust appears (no zinc layer peeling), gently polish the rust with fine sandpaper (800 grit or above), then apply anti-rust oil; if the zinc layer peels off (area ≤1cm²), spray zinc-based repair agent (commercially available general type) to form a protective film after drying, without affecting use; if rust is severe (area ＞5cm²), contact after-sales service to replace components to avoid structural strength reduction.
A4: Most jamming is caused by insufficient lubrication or foreign matter entry, which can be checked and solved by yourself. The steps are as follows:
- Foreign Matter Check: Turn off the freewheel, check if there is metal debris or dust in the ratchet-pawl engagement area (easily accumulated in workshop scenarios), clean the foreign matter with a brush, and then try rotating the handle;
- Lubrication Maintenance: If jamming persists after cleaning, open the oil filling hole on the side of the puller, inject 5-10ml lithium-based grease (avoid using engine oil, which easily absorbs dust), and rotate the handle 5-10 times to relieve jamming;
- Fault Judgment: If jamming still exists after the above operations, the pawl spring may be broken or the ratchet may be worn (e.g., tooth deformation). Stop using it immediately, contact after-sales service and provide the model (YD30-001) to replace components—do not force rotation to avoid further damage.
