The YEEDA YD52-009A-E Trolley-Mounted Grease Dispensing Kits solve the pain points of mobile grease dispensing: "drum size mismatch, limited mobility, and inefficient greasing". With "5 model drum compatibility + 50:1 high-pressure pump + zinc-plated trolley" as core strengths, they deliver flexible, efficient greasing for diverse workplaces:
- 5 Drum Size Options: From YD52-009B (280mm cover for 20-30kg drums) to YD52-009E (420mm cover for 50-60kg drums), the series fits nearly all 20-60kg drum sizes. The follower plates (265mm-410mm) ensure tight sealing with drum interiors, preventing grease contamination and waste.
- Base Model Flexibility: YD52-009A (no extra cover/plate) works with existing standard drum covers, ideal for users who already have compatible drums.
- 50:1 Pump for Thick Grease: The 400 Bar max flow pressure pushes high-viscosity grease (up to SAE240) into narrow machinery gaps (e.g., bearing races, hydraulic joints). The 800g/Min capacity cuts greasing time by 30% vs. manual guns.
- 4m SAE 100R2AT Hose: The oil-resistant, high-pressure hose enables greasing from 4m away—no need to move the heavy trolley repeatedly. Its flexibility reaches hard-to-access points (e.g., under-carriage of construction vehicles).
- Zinc-Plated 20-60kg Trolley: The rust-resistant trolley rolls easily on wheels/casters, carrying both drum and pump. At 19kg, it’s light enough for one person to maneuver, saving labor vs. carrying drums manually. Modular design allows compact storage when not in use.
- 4-Jaw Grease Gun: The triple swivel joint and 4-jaw coupler ensure easy attachment to machinery ports—no leakage during greasing. The rigid terminal reduces hand fatigue during long sessions (e.g., greasing a fleet of trucks).
Scenario Requirement: A car repair shop uses 25kg grease drums (280mm diameter) to lubricate 30 cars daily (each needing 150g engine grease). The shop needs a compact, mobile solution.
Operation Process:
- Setup: Secure a 25kg drum to YD52-009B’s trolley; attach the 280mm drum cover and 265mm follower plate; connect the pump to the shop’s air compressor (8 Bar);
2. Greasing: Use the 4m hose and grease gun to lubricate each car—150g grease takes ~11 seconds (800g/Min); the 4-jaw coupler ensures no leakage;
3. Efficiency: 30 cars serviced in ~5.5 minutes; trolley moves easily between repair bays;
4. Compatibility: Follower plate seals tightly with the 25kg drum, no grease contamination.
Effect: Small-drum compatibility fits workshop needs; mobile design optimizes workflow.
Scenario Requirement: A construction site uses 50kg grease drums (385mm diameter) to lubricate 8 excavators (each needing 4kg grease) weekly. The site requires high pressure for thick grease and outdoor durability.
Operation Process:
- Setup: Load YD52-009D’s trolley with a 50kg drum; attach the 385mm cover and 370mm follower plate; connect to a portable air compressor;
2. Greasing: Use the 4m hose to reach excavator hydraulic joints; 50:1 pump pushes thick grease (SAE240) into components—4kg takes ~5 minutes per excavator;
3. Durability: Zinc-plated trolley resists outdoor rain/dust; 400 Bar hose withstands high pressure;
4. Mobility: Trolley rolls on gravel paths, no need for forklift assistance.
Effect: High pressure handles thick grease; outdoor-friendly build ensures reliability.
Scenario Requirement: A factory uses 60kg grease drums (420mm diameter) to maintain 12 industrial machines (each needing 2kg grease) monthly. The plant needs efficient long-distance greasing.
Operation Process:
- Setup: Position YD52-009E near the machine area; attach the 420mm cover and 410mm follower plate; connect to the factory’s air supply;
2. Greasing: Extend the 4m hose to each machine; 800g/Min capacity dispenses 2kg grease in ~2.5 minutes per machine;
3. Safety: Max flow pressure (400 Bar) ensures thorough lubrication without over-greasing; 4-jaw coupler prevents spills;
4. Storage: Modular trolley folds compactly when not in use, saving warehouse space.
Effect: Long hose fits plant layouts; large-drum compatibility reduces refilling frequency.
A1: Leaks are usually due to size mismatch or improper installation. Solutions: 1) Check Model Compatibility: Ensure the follower plate diameter matches the drum (e.g., YD52-009D’s 370mm plate for 385mm drum); 2) Install Correctly: Press the follower plate firmly into the drum to create a tight seal—avoid tilting, which leaves gaps; 3) Replace Worn Plates: If the plate’s rubber seal is cracked, replace it with a manufacturer-supplied seal (worn seals cause leaks).
A2: No. The pump’s 50:1 compression ratio is optimized for SAE240 or lower. Using SAE300+ grease will: 1) Reduce flow rate to 400-500g/Min (50% lower than rated); 2) Strain the pump’s internal components, shortening service life by 50%; 3) Clog the 30mm suction tube or 1/4” hose. For SAE300+, use a kit with a 65:1 pump (e.g., YEEDA YD52-008 series).
A3: Coupler issues are due to dirt or size mismatch. Fixes: 1) Clean the Coupler: Wipe the 4-jaw coupler with a cloth to remove grease/debris—buildup blocks attachment; 2) Check Port Size: The coupler fits standard machinery lubrication ports (M6-M12); if ports are non-standard, use a coupler adapter (available from the manufacturer); 3) Adjust Coupler Pressure: Squeeze the gun’s trigger slightly while attaching the coupler—this helps the jaws lock onto the port.
A4: 1) Trolley Maintenance: Wipe the zinc-plated frame with a dry cloth after use to remove grease; touch up scratches with zinc-rich paint to prevent rust; lubricate wheels/casters quarterly; 2) Pump Maintenance: Flush the pump with low-viscosity oil after use to clear residual grease; clean the 30mm suction tube monthly; add air tool oil to the pump’s air inlet weekly to keep the motor running smoothly; 3) Storage: Empty the drum and hose before long-term storage; keep the kit in a dry, ventilated area to avoid humidity damage.
