II. Product Details (PRODUCT DETAILS)

1. Graded Load + Variable Speed Design, Labor-Saving & Efficient

(1) Precise Gear Ratio Matching, Pulling Heavy Loads with Light Force

• Low-Load Models (001-002, 250-363kg): Adopt 3.2:1 gear ratio. Each handle shake can drive the strap to retract/release about 60mm, and only about 80N of force (equivalent to lifting an 8kg object) is needed to pull a 250kg heavy load, making it easy for women or the elderly to operate;
• Medium-to-High Load Models (003-011, 450-1600kg): Basic gear ratio is 4.1:1, and high-load models (007-011) additionally have an 8.1:1 low-speed gear – the high-speed gear (4.1:1) is suitable for fast retraction/release of empty straps or light loads, while the low-speed gear (8.1:1) can amplify torque. When pulling a 1600kg heavy load, the applied force is ≤200N (equivalent to lifting a 20kg object), avoiding fatigue caused by brute force operation.

(2) 2-Way Operation + Brake Locking, Safe & Flexible

• 2-Way Operation: Supports clockwise/counterclockwise handle shaking, enabling both "traction" and "relaxation" functions. For example, during camping, it can pull a trailer and slowly lower heavy objects without disassembling the winch to adjust direction;
• Instant Braking: Built-in ratchet brake structure. The strap locks automatically when the handle is released, preventing load sliding even if the hand slips. For example, when lifting 650kg backyard stone, you can pause at any time to adjust the position, and the brake system locks the strap without displacement, solving the pain point of "needing continuous force" with traditional hand winches.

2. Durable Materials + Detail Optimization, No Performance Attenuation in Long-Term Use

(1) Solid Gears + Tough Strap, Maximum Ruggedness

• Durable Gears: Solid gears have no hollow design, and their impact resistance is 100% higher than that of hollow gears. After 100 consecutive shakes under a 1600kg load, the gear surface wear is only 0.02mm, with a service life of more than 5000 load operations;
• Tough Strap: Polyester fiber strap with PVC coating has a tear resistance ≥300N. Even if scratched by sharp stones (no penetrating damage), it can still maintain more than 90% load capacity; no cracking after repeated bending at low temperatures (-20℃) and no softening at high temperatures (60℃), adapting to full-temperature outdoor scenarios.

(2) Dual Surface Treatments, Adapting to Multiple Environments

• Black Electrostatic Discharge Coating: Smooth and scratch-resistant, suitable for dry scenarios such as backyards and camping. Daily dust can be wiped off with a dry cloth, and no paint peeling occurs during long-term use;
• Zinc Plated Finish: Zinc layer thickness ≥8μm, no rust when used in humid environments (e.g., basements, ship decks), and even resistant to short-term rain, suitable for outdoor humid scenarios.

3. Lightweight + Easy Installation, No Portable Burden

(1) Lightweight Design, Convenient for Mobile Handling

(2) Universal Mounting Holes, Adapting to Multiple Scenarios

III. Application Scenarios (APPLICATION SCENARIOS)

1. Outdoor Camping Trailer/Equipment Handling (Core Scenario: Models 001-005, 250-650kg)

1. Temporary Installation: Select Model YD30-012A-004 (550kg load), hang the winch on a tree at the campsite entrance with the accessory hook, ensuring firm fixation;
2. Strap Connection: Fix the hook at the end of the strap to the trailer tow ring, adjust the strap tightness, switch the handle to 4.1:1 high-speed gear, and quickly retract/release the strap until it is tight;
3. Traction Operation: Switch to normal operation, shake the handle to pull the trailer. Due to the labor-saving gear ratio, one person can pull the trailer to the campsite within 20 minutes; when a pause is needed halfway, release the handle to lock the brake without continuous force application;
   Result: Replacing the traditional "4-person pushing + wooden block anti-slip", the number of operators is reduced by 75%, and the time is shortened from 1 hour to 20 minutes. No power dependence, adapting to wild camping scenarios.

2. Backyard/Farm Heavy Object Movement (Scenario 2: Models 006-009, 700-1100kg)

1. Fixed Installation: Select Model YD30-012A-008 (900kg load, 2-speed), fix the winch to the backyard load-bearing column with expansion bolts;
2. Heavy Object Traction: Wrap the strap around the traction point at the bottom of the sculpture, fix the hook, switch to 8.1:1 low-speed gear, and slowly shake the handle to pull the sculpture; due to the brake locking function, you can pause every 1 meter to adjust the sculpture direction;
3. Farm Operation: Fix the winch to the rear bracket of the tractor, and use 4.1:1 high-speed gear to quickly retract the strap when pulling the 800kg irrigation device, increasing efficiency by 50%;
   Result: No multi-person collaboration is needed – one person can complete heavy object movement, avoiding waist injuries caused by manual handling. Backyard operation efficiency is increased by 80%, and farm operation adapts to narrow field paths.

3. Temporary Ship/Dock Fixation (Scenario 3: Models 003-011, 450-1600kg)

1. Ship Fixation: Select Model YD30-012A-009 (1100kg load) with zinc plated finish for humid environments, fix the winch to the pier bracket, connect the strap to the boat mooring ring, shake the handle to tighten the strap, and the boat remains stable after brake locking;
2. Fish Crate Handling: Use Model YD30-012A-006 (700kg load), bind the fish crate with the strap, and use 2-way operation to slowly pull the fish crate to the warehouse, avoiding fish loss due to crate tipping;
   Result: Replacing the traditional "manual rope pulling + knot fixing", the fixation is more secure, and the fish crate handling efficiency is increased by 60%. No rust occurs after 1 year of use in humid environments, reducing maintenance costs.

IV. Frequently Asked Questions (FAQ)

Q1: There is a large load difference between different models. How to choose the right model for myself?

1. Prioritize actual load: Select a model with a rated load 20% higher than the actual load (e.g., choose a model with ≥600kg load for pulling 500kg, such as 004 or 005) to reserve a safety margin;
2. Consider scenario needs: Choose models 001-005 (250-650kg) for outdoor camping and light home use, as they are more portable; choose models 006-011 (700-1600kg) for backyard heavy loads, farm/dock use, as they offer better durability and labor-saving performance; choose models with 2-speed (008-011) for needs of fast retraction/release.

Q2: Can the strap continue to be used after being scratched by sharp objects? How to repair it?

1. Usable condition: If only the surface PVC coating is scratched without damaging the internal polyester fibers (no fiber breakage), it can still bear ≤70% of the rated load. For example, a 50mm strap with scratched coating can pull ≤490kg for the 700kg model;
2. Repair method: Apply special strap repair glue (accessories can be purchased separately) to minor damage, and it can restore 80% strength after drying; if ≥3 fibers are broken or there is a crack (length ＞10mm), replace with a new strap (original straps are compatible with each model separately) to avoid breaking risks.

Q3: After using the winch for a period of time, it becomes difficult to shake. Is this a fault? How to solve it?

1. Cause: Lubricating oil on gears and pins is lost after long-term use, increasing friction and causing difficulty in shaking;
2. Solution: Disassemble the gear cover with a wrench, clean internal dust, and apply lithium-based grease (ordinary butter is acceptable) to the gear meshing area and pins. After applying, shake 3-5 times, and the difficulty in shaking will be resolved; it is recommended to maintain once every 50 uses or 3 months of storage.

Q4: When used outdoors, will the winch be affected by rain or sun exposure, and will it affect its service life?

1. Rain Protection: Zinc-plated models can withstand short-term rain. After use, wipe the surface moisture with a dry cloth and apply anti-rust oil to the gears; black coated models should be wiped dry in time after rain to avoid rust under the coating;
2. Sun Exposure Protection: Long-term sun exposure will accelerate strap aging. It is recommended to retract the strap into the drum when not in use or cover the winch with a waterproof cloth to avoid direct sunlight; if the strap becomes slightly hardened, apply a small amount of strap maintenance agent (such as silicone-based lubricant) to restore flexibility.
