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.
