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.
