Product Details
The YEEDA YD52-010 Trolley-Mounted Grease Dispenser Kit addresses the key pain points of mobile grease dispensing: "drum incompatibility, limited mobility, inefficient high-viscosity transfer, and grease waste". With 50:1 high-pressure pump + galvanized trolley + 4m long hose as core strengths, it redefines efficiency for industrial grease application:
50:1 Pump & 940mm Length: Power for Tall Drums
- 400 Bar Pressure for Thick Grease: The 50:1 compression ratio generates enough force to transfer SAE240 high-viscosity grease--ideal for heavy machinery like excavators, industrial gearboxes, and fleet trucks. Unlike low-ratio pumps that struggle with thick grease, this design ensures consistent flow.
- 940mm Pump for Maximum Grease Utilization: The extra-long pump reaches the bottom of tall 20-60kg drums, minimizing residual grease (≤300g per drum) and reducing waste by 20% compared to shorter pumps. The 30mm suction tube further enhances grease extraction.
Galvanized Trolley: Durability & Mobility
- Fully Galvanized Finish: Unlike painted trolleys that chip and rust, the galvanized surface resists grease stains, rain, and humidity--perfect for outdoor construction sites or humid workshops. Its 35kg weight balances stability (no tipping during dispensing) and mobility (easy to move by one person).
- 20-60kg Capacity & Modular Design: The trolley fits all standard 20-60kg drum shapes, eliminating the need for multiple trolleys. Its compact, modular structure saves storage space--critical for small workshops with limited area.
Flexible Hose & Precision Grease Gun: Convenience & Accuracy
- 4m SAE 100R2AT Hose: The long, pressure-resistant hose allows greasing from 4m away, so users don't need to reposition the heavy trolley repeatedly. This saves 30% of labor time when servicing scattered machinery.
- 4-Jaw Grease Gun: The triple swivel joint enables access to hard-to-reach points (e.g., under-carriage of trucks), while the 4-jaw coupler ensures a leak-free seal. This precision prevents grease spills, keeping workspaces clean and reducing waste.
Application Scenarios
Construction Site Excavator Greasing
Scenario Requirement: A construction site lubricates 8 excavators (each needing 5kg SAE240 grease for hydraulic joints) weekly using 60kg drums. The site requires outdoor durability and mobile operation.
Operation Process:
- Setup: Secure a 60kg grease drum to the YD52-010 trolley; attach the 600mm drum cover and 585mm follower plate; connect the pump's F1/4"G air inlet to a portable air compressor (8 Bar)
- Greasing: Extend the 4m hose to reach excavator hydraulic joints; use the grease gun's triple swivel joint to access tight spots--5kg grease per excavator takes ~6.25 minutes (800g/Min)
- Mobility: Move the trolley between excavators (parked 50m apart) with minimal effort; galvanized finish resists rain and site dust
- Efficiency: 8 excavators serviced in ~50 minutes; residual grease ≤300g per drum
Effect: High pressure handles thick grease; outdoor-friendly trolley suits site conditions; long hose optimizes workflow.
Industrial Workshop Gearbox Maintenance
Scenario Requirement: A manufacturing workshop maintains 12 industrial gearboxes (each needing 2kg gear grease) daily using 40kg drums. The workshop needs efficient, clean greasing to avoid production downtime.
Operation Process:
- Setup: Position the YD52-010 trolley near the gearbox area; connect the pump to the workshop's air supply
- Greasing: Use the 4-jaw grease gun to dispense 2kg grease per gearbox in ~2.5 minutes; the coupler's leak-free design keeps gearboxes and floors clean
- Stability: The trolley's 35kg weight prevents tipping during dispensing; fixed wheels lock into place for steady operation
- Productivity: 12 gearboxes serviced in ~30 minutes--no disruption to production lines
Effect: Fast flow meets daily demand; leak-free design ensures cleanliness; stable trolley enhances safety.
Fleet Maintenance Center Truck Lubrication
Scenario Requirement: A logistics center services 15 delivery trucks (each needing 1.5kg motor grease) weekly using 30kg drums. The center needs to service trucks in different bays and track grease usage.
Operation Process:
- Setup: Load a 30kg drum onto the trolley; connect the pump and hose; reset the grease gun's optional meter (if used) to zero
- Lubrication: Move the trolley to each truck bay; use the 4m hose to reach truck wheel bearings and engine parts--1.5kg grease takes ~1.875 minutes per truck
- Tracking: The pump's consistent 800g/Min flow allows easy calculation of grease used per truck
- Storage: After use, the trolley's modular design folds compactly into the center's storage room
Effect: Mobile design fits bay-to-bay service; consistent flow simplifies usage tracking; compact storage saves space.
Frequently Asked Questions
Q1: The pump's flow rate drops below 800g/Min when using SAE240 grease. How to fix?
A1: Reduced flow is typically due to insufficient air pressure or grease viscosity. Solutions:
- Check Air Supply: Ensure the air compressor provides 8 Bar pressure--low pressure (≤7 Bar) reduces pump power
- Warm the Grease: Heat the 60kg drum to 25-30℃ (using a drum heater) to lower SAE240 grease viscosity
- Clean the Suction Tube: Disconnect the 30mm tube and flush it with low-viscosity oil to remove dried grease buildup
These steps restore the 800g/Min flow rate.
Q2: Can the trolley handle drums heavier than 60kg (e.g., 80kg)?
A2: No. The trolley's maximum load capacity is 60kg--exceeding this limit will cause:
- Trolley Damage: The wheels or frame may bend under excess weight, rendering the trolley unusable
- Safety Risks: Overloaded trolleys tip easily, causing drum spills and potential operator injury
- Reduced Pump Performance: The 940mm pump is not designed for taller 80kg drums, leading to incomplete grease extraction
For 80kg drums, use a heavy-duty trolley rated for ≥100kg and confirm pump compatibility with the manufacturer.
Q3: The grease gun's 4-jaw coupler won't lock onto machinery ports. What's the issue?
A3: Coupler locking issues stem from debris or port size mismatch. Fixes:
- Clean the Coupler: Wipe the 4-jaw mechanism with a dry cloth to remove grease or dirt--buildup prevents jaws from closing
- Check Port Compatibility: The coupler fits standard machinery ports (M6-M12); if ports are smaller/larger, use a compatible adapter (available from YEEDA)
- Adjust Coupler Pressure: Squeeze the grease gun trigger slightly while pushing the coupler onto the port--this helps the jaws engage securely
Q4: How to maintain the galvanized trolley and pump for long-term use?
A4: Key maintenance steps:
- Trolley Care: Wipe the galvanized frame with a damp cloth after use to remove grease; inspect for scratches--touch up with galvanized spray paint to prevent rust; lubricate wheel bearings and casters quarterly with oil-resistant lubricant
- Pump Maintenance: Flush the pump with 500ml of low-viscosity oil (e.g., SAE30) after each use to clear residual grease; clean the 30mm suction tube monthly; add 5-10 drops of air tool oil to the pump's air inlet weekly to keep the motor running smoothly
- Storage: Empty the drum and hose before long-term storage; keep the kit in a dry, ventilated area--avoid storing the trolley outdoors to prevent premature galvanization wear
