II. Product Details (PRODUCT DETAILS)

1. Heavy-Load Structure + Quenched Wheels, Excellent Load-Bearing and Durability

(1) Rolled Steel Side Frames, Torsion & Compression Resistance Without Deformation

• Superior Strength: Side frame thickness ranges from 8mm to 15mm (thicker for heavier loads). The 3T model side frame can withstand a 4.5T test load without bending, and its torsional stiffness is 1.8 times that of welded side frames, suitable for long-term handling of heavy equipment in workshops;
• Strong Protection: Side frames extend 50mm-80mm beyond the outer side of the wheels. When the trolley encounters obstacles (such as raised track joints) during operation on the track, the side frames can first contact and buffer, avoiding direct wheel collision and damage, and extending wheel service life.

(2) Alloy Cast Iron Wheels, Wear-Resistant & Adaptable to Multiple Tracks

• High Hardness & Wear Resistance: Alloy cast iron is fully quenched, with wheel tread hardness much higher than ordinary cast iron. The 10T model wheels run 1000 times on 125-180mm I-beam tracks with only 0.03mm tread wear, and their service life is twice that of ordinary wheels;
• Wide Track Adaptability: The tread adopts a universal design, enabling stable operation on flat or tapered I-beam flanges. It can adapt to I-beams of different specifications (75mm-180mm) without wheel replacement, reducing equipment replacement costs;
• Stable Operation: Wheels have high machining accuracy with a wheel diameter error ≤0.1mm, ensuring uniform contact area with the track. There is no jitter or deviation during pushing, and even under full load, it can maintain linear operation to avoid heavy load shaking.

2. Ball Bearings + Low-Resistance Design, Labor-Saving & Efficient Pushing

(1) Lifetime Lubricated Bearings, Maintenance-Free & Worry-Free

• Maintenance-Free: High-temperature lithium-based grease is filled in the bearings at the factory, and the seal cover prevents dust and oil from entering. No disassembly or lubricant addition is required under normal use, reducing maintenance workload;
• Low Resistance & High Efficiency: The transmission resistance of ball bearings is much lower than that of sliding bearings. The pushing force of the 0.5T model is only 7.5N (equivalent to lifting a 0.75kg object), and the pushing force of the 10T model ≤150N. Two people can easily push the fully loaded trolley, improving handling efficiency.

(2) Humanized Operation, Adaptable to Multi-Scenario Collaboration

• Flexible Operation Space: The trolley has no complex control components and can be moved by simply pushing the load or the trolley handle. Even in scenarios with dense workshop equipment and narrow space around the track, steering and positioning can be completed by single or double-person collaboration;
• Precise Positioning: Wheel speed matches pushing speed linearly with no inertial sliding. When handling precision equipment (such as machine tool components), it can be slowly pushed to the target position with no deviation when stopped, meeting high-precision alignment requirements.

3. Full-Scenario Adaptation + Easy Matching, Low Usage Cost

(1) Multi-Track Compatibility, No Infrastructure Modification Needed

• Workshop Scenarios: Suitable for existing I-beam tracks of 75mm-180mm specifications, which can be directly installed and used without track replacement. For example, when upgrading handling equipment in old workshops, traditional trolleys can be directly replaced, reducing transformation costs;
• Construction Scenarios: Can be used on temporarily built I-beam tracks. The wheels have strong impact resistance and can still run stably even if the track has slight unevenness (error ≤2mm/m), adapting to the changeable environment of construction sites.

(2) Easy Matching with Lifting Equipment, Strong Function Expansion

• Matching with Chain Blocks: The lower hook of the trolley can hang YD30-013/014 series chain blocks to achieve integrated "vertical lifting + horizontal movement" operations. For example, when handling 5T heavy shelves in a warehouse, the shelves are first lifted by the chain block, then the trolley is pushed to move to the target position;
• Matching with Electric Hoists: Supports hanging electric hoists (load-matched), suitable for high-frequency and heavy-load handling scenarios. For example, in workshop production line material transfer, electric hoists are used for rapid lifting, and trolleys are used for horizontal movement positioning, improving overall operation efficiency.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Factory Workshop Equipment Handling (Core Scenario: Models 1T-10T)

1. Equipment Installation: Select the YD30-016-10T model trolley, install it on the workshop I-beam track, and check the fit between the wheels and the track; hang the YD30-013-10T chain block on the lower hook to ensure a firm connection;
2. Vertical Lifting: Use the chain block to lift the machine tool spindle (8T) from the ground to a height of 1.5 meters to avoid collision with ground obstacles during handling;
3. Horizontal Movement: Two people collaborate to push the trolley. Due to the low-resistance design of ball bearings, the pushing force is only 120N, and the spindle is slowly moved to Area B; when a pause is needed for adjustment halfway, the pushing force is released to stop stably with no sliding risk;
4. Precise Lowering: After reaching the target position, slowly lower the spindle to the designated base through the chain block to complete handling.
   Result: Replacing the traditional "4-person + hydraulic jack + roller" handling method, the number of operators is reduced by 50%, and the handling time is shortened from 2 hours to 30 minutes, avoiding spindle collision damage and adapting to the handling of precision equipment in workshops.

2. Warehouse Heavy Cargo Transfer (Scenario 2: Models 0.5T-5T)

1. Trolley Installation: Select the YD30-016-5T model, install it on the second-floor I-beam track, and hang the YD30-014-5T lever block on the lower hook;
2. Cargo Lifting: After the shelves are transferred to the second floor by elevator, use the lever block to lift the shelves to a height of 1 meter (to avoid ground friction);
3. Horizontal Transfer: One person pushes the trolley. Due to the low-resistance design of the wheels, pushing is easy without jitter. Pause every 5 meters to check the shelf position, and finally move it to the target shelf area precisely;
4. Stable Lowering: Slowly lower the shelves to the ground guide rail to complete the transfer.
   Result: Warehouse handling efficiency is increased by 80%, no reliance on large equipment such as forklifts, adapting to multi-floor and multi-area cargo flow in the warehouse. The operation is flexible, avoiding shelf collisions.

3. Construction Material Hoisting (Scenario 3: Models 3T-10T)

1. Temporary Installation: Select the YD30-016-10T model, install it on the temporary I-beam track of the construction platform, and hang an electric hoist (10T load-matched) on the lower hook;
2. Vertical Hoisting: The electric hoist lifts the ground steel bundles to the height of the construction platform (10 meters) to avoid collision with scaffolding;
3. Horizontal Handling: Two people push the trolley. The wheels adapt to the slight unevenness of the track, running stably without shaking, and the 50-meter distance can be completed in only 10 minutes;
4. Precise Unloading: After reaching the pouring point, the electric hoist slowly lowers the steel bundles to the designated position to complete the operation.
   Result: Replacing the traditional "tower crane + manual traction" method, horizontal handling efficiency is increased by 60%, no need to occupy the tower crane for a long time, adapting to the multi-process collaboration needs during the peak construction period.

IV. Frequently Asked Questions (FAQ)

Q1: How to choose the right model based on existing tracks and loads?

1. Load Matching: Select a model with a rated load 20% higher than the actual load (e.g., for handling an 8T machine tool spindle, choose the 10T model with a test load of 15T to reserve a safety margin);
2. Track Adaptation: Choose based on the I-beam flange width: 0.5T-1T models for 75-125mm, 1.5T-3T models for 100-150mm, and 5T-10T models for 125-180mm, ensuring the wheel width matches the track;
3. Scenario Intensity: Choose 5T-10T models (thicker side frames and more wear-resistant wheels) for high-frequency and heavy-load (≥5T) use, and 0.5T-2T models for low-frequency and light-load (≤2T) use to balance cost and durability.

Q2: The trolley jitters during operation on the track. Is this a fault? How to solve it?

1. Track Issues: If the track is deformed (e.g., flange bending), has raised joints, or oil accumulation, first clean the track oil, calibrate the track flatness with a level (error ≤2mm/m), and grind the raised joints to ensure a smooth track;
2. Foreign Objects on Wheels: If metal chips, bolts, or other foreign objects are stuck between the wheels and the track, stop operation, remove the foreign objects with tools, and check if there are scratches on the wheel tread. If the scratches are shallow (≤0.1mm), continue use; if deep, replace the wheels.

Q3: After long-term use, the wheels are severely worn. How to judge if replacement is needed?

1. Excessive Wear: Wheel tread wear depth ≥1mm, or obvious shaking during trolley operation due to wheel diameter wear (deviation ≥5mm/m);
2. Abnormal Operation: Periodic jitter and abnormal noise during pushing, or reduced contact area between wheels and track (≤70% of the original contact area), leading to increased pushing resistance (exceeding 2% of the rated load);
3. Replacement Suggestions: Prioritize original wheel accessories. When replacing, check the bearing status simultaneously. If the bearing has abnormal noise or jitter, replace the bearing synchronously to ensure smooth trolley operation.

Q4: How to prevent the trolley from rusting and damage when used outdoors or in humid environments?

1. Pre-Use Protection: Apply anti-rust oil (such as lithium-based anti-rust grease) to the surface of metal components such as side frames and wheels, especially the bearing seal of the wheels, to prevent moisture from entering and causing bearing rust;
2. Post-Use Maintenance: After each use, wipe the trolley surface dust and mud with a dry cloth. If exposed to rain, rinse with clean water, dry it, and then apply a thin layer of anti-rust oil;
3. Long-Term Storage: If not used for a long time (more than 1 month), remove the trolley from the track, place it in a dry and ventilated place, place wooden blocks under the wheels to avoid direct contact with the ground, and check the anti-rust status regularly (every 3 months) and reapply anti-rust oil.
