The EAE Model No. EE-MR30 is a short platform scissor lift designed for lifting motor vehicles. It is intended for mobile use, with a maximum lifting height of 1000mm and a lifting capacity of 3000kg. The lift operates on an electro-hydraulic system, where a gear pump delivers hydraulic oil to cylinders, pushing pistons upwards to raise the lifting platforms.
Function Description:
The EE-MR30 is a chassis-supporting vehicle lift. It is designed to lift the entire body of vehicles, with its maximum weight within the lifting capacity. The lift incorporates several safety features to ensure operator security and prevent unexpected falls or tip-overs. It is primarily for indoor use on stable, level, dry, and non-slippery surfaces capable of sustaining the load, specifically solid concrete floors with no more than a 3-degree slope.
Important Technical Specifications:
- Model No.: EE-MR30
- Type: Short Platform Scissor Lift, Mid Rise
- Lifting Capacity: 3000kg
- Full Rising Height: 1000mm
- Initial Height: 105mm
- Full Rising Time with Load: ≤30s
- Full Lowering Time with Load: <30s
- Hydraulic Pressure: 26MPa
- Oil Tank Capacity: 5L
- Control Box Voltage: 24V (safe voltage for users)
- Noise Level: Less than 70dB(A) during operation
- Dimensions (Lifting Platform): 2028mm (79 13/16") length, 1420mm (55 7/8") width
- Total Dimensions (Fixed Installation): Approximately 6000mm length, 2200mm width, 4000mm height (including clearance)
- Power Unit: 2.2kW (available in various voltages: 230V-1PH-50HZ-2P, 400V-3PH-50HZ-2P, 220V-1PH-50HZ-2P, 240V-1PH-50HZ-2P, 380V-3PH-50HZ-2P, 415V-3PH-50HZ-2P)
Usage Features:
- Electro-Hydraulic System: Provides smooth and controlled lifting and lowering operations.
- Mechanical Locking Unit: Ensures no unexpected fall in case of hydraulic system failure, enhancing safety.
- 24V Control Box and Limit Switch: Designed with low voltage for operator safety.
- Anti-Surge Valves: Prevent quick descent in case of hydraulic failure.
- Tip-Over Protection: Guards against tip-over in case of unbalanced load distribution.
- Height Limit Switch: Ensures operation within the designed stroke.
- Feet Protection Fenders: Guard against pinching and shearing injuries.
- Mobile Kit (Optional): Allows for easy movement of the lift. The portable kit should be installed when the platform is about 500mm above the floor, and removed before loading. The lift should never be transported when loaded.
- Control Panel: Features a power switch (QS), power indicator (HL), UP button (SB1) for rising, and DOWN button (SB2) for lowering. The control buttons operate as "hold to run."
- Load Capacity vs. Initial Height: The lift's ability to handle heavier vehicles is dependent on the initial loading height. For instance, to lift an 1800kg vehicle, the platform must be raised to at least 210mm; for 2200kg, 270mm; and for 2700kg, 310mm. Users must consult a chart to determine the suitable initial height based on the vehicle's self-weight and any accessories that might affect the loading height.
- Installation Requirements: Requires a minimum 1-meter clearance between the lifting platform and fixed elements (e.g., walls) in all lifting positions, and sufficient space for driving vehicles on and off. A C25-C30 concrete foundation with a minimum thickness of 150mm is required for fixed installation.
Maintenance Features:
- Daily Checks:
- Control buttons: Check for proper "hold-to-run" function.
- Max height limit switch: Inspect to ensure the lift stops rising at maximum height.
- Oil hoses and connectors: Inspect for leakage.
- Mechanical safety catch: Check if both catches engage and disengage simultaneously.
- Hydraulic block and valves: Inspect for leaks, clean or change if necessary.
- Every 3 Months:
- Terminals in the control unit: Open, inspect, and screw firmly if loose.
- Joint shafts: Add grease into oil cups.
- Circlips: Inspect if any circlip is off its groove and ensure proper positioning.
- Rolling wheels and their running tracks: Check for over-wear, add grease for smooth running, change over-worn wheels if necessary.
- Every 6 Months: Change hydraulic oil after initial use.
- Every Year: Change hydraulic oil thereafter. Inspect the hydraulic oil and change if it becomes black or dirty.
- Hydraulic Oil Type: HM NO.46 is suggested; HM NO.32 for temperatures below 10°C.
- Self-Locking Nut: Check with a torque spanner; torque should be no less than 330N.m (every 3 months).
- Whole Lift Operation: Run the lift for several cycles with and without rated load to ensure steady and smooth operation without abnormal noise (every 3 months).
- Long-Term Storage: Disconnect power, empty the oil tank, and lubricate moving parts with hydraulic oil.
The manufacturer emphasizes the importance of reading the entire manual carefully before installation or operation, and that only properly trained personnel aged 18 or above should operate the lift. Regular checks by a qualified person are required, at least annually, and exceptional checks after structural modifications or major repairs.
