The SXJS3018 Double-Deck Scissor Lift is a robust and versatile lifting device designed for high-precision wheel alignment and automotive repair and maintenance. It utilizes a scissor-type mechanical structure, hydraulic pressure for lifting, and air pressure to control the locking and loosening of its components. The lift is characterized by its simple structure, advanced technology, ease of operation, and safety features.
Function Description:
The lift operates by generating lifting power through its hydraulic system, while a pneumatic system manages the mechanical locks. A mechanical lock system ensures security, and a hydraulic balance valve maintains the lifting platform's level. The double-deck design allows for comprehensive vehicle servicing.

Usage Features:
- Installation: Designed for underground installation, which saves floor space and offers flexible placement. The control cabinet's location can be interchanged (left or right).
- Safety:
- Pressure-controlled safety mechanical locks ensure secure operation.
- Equipped with an emergency decline manual pump interface, allowing vehicles to be lowered manually during a power cut.
- Series synchronous hydraulic pressure loop provides good synchronization and high horizontal precision.
- Strict adherence to the manual is required; only trained and qualified staff should operate the lift.
- Before installation, verify the motor's voltage, phase, and rotation direction. Incorrect rotation can damage the gear pump.
- For equipment use below 10 degrees Celsius, ensure compressed air passes through an effective water filter.
- Maintain a safe distance from the lift and equipment during operation; no standing above or under the equipment, and no staff should remain in the car on the lift.
- The vehicle's weight must not exceed the machine's lifting capacity.
- Remove all barriers around and under the platform before operation.
- When driving a car onto the lift, ensure the vehicle's centerline aligns with the lift countertops' centerline.
- Leveling should be performed on an unloaded platform; opening the balancing valve with a car on the platform is strictly prohibited.
- For prolonged periods of inactivity or overnight, lower the equipment to its lowest position, remove the vehicle, and cut off power.
- The mechanical lock's reliability and normal function are crucial for safety. Avoid placing hands or feet in the middle part of the flats during lifting or before the mechanical lock is fully engaged.
- If the power is suddenly cut off while the lift is raised, switch off the electrical source, then use the manual pump on the hydraulic power unit to open the protection lock, locate the cut-off valve (4 in Fig. 5), and slowly lower the platform by slightly loosening its screw. Remember to fasten the screw after the operation.
- Operation:
- Turn on the electrical source; the indicator light will illuminate.
- Press the UP button to lift platforms. If platforms are not level, adjust the balancing valves (refer to Fig. 5).
- Press the descending button to check normal falling status.
- Lower the platform to its lowest position before driving a vehicle on.
- Place rubber pads under the vehicle, aligning lift points directly with the pads.
- Press the UP button briefly, then continuously until the desired repair/testing height is reached.
- Press the LOCK button to engage the upper lock teeth in the lower lock jaw bottom before starting work.
- Monitor platform synchronization during lifting; stop immediately if not synchronous and rectify.
- After work, ensure no obstructions are under or around the lift. Press the UP button to open the safety lock, then press the DOWN button to lower the platform to its lowest position and drive the vehicle away.
- Turn off the switch, air compressor, and power supply after operation.
- Adjustment:
- Leveling: If platforms are not level, adjust balancing valves (valve 8 in Fig. 5). For the main platform (thicker cylinder) being lower, open valve 8 and press UP until level. For the sub-platform (thinner cylinder) being higher, open valve 8 and press DOWN until level. Repeat as necessary. This operation is prohibited when the lift is under load.
- Horizontal Adjustment: Lift platforms about one meter, engage the LOCK button, ensuring mechanical locks fall into the same lock tooth. Adjust the space around the lifts. Use a leveling tool to ensure front, back, left, and right platforms are level within ≤3mm tolerance. Use washers or steel/cement fill under the floor plate if needed, then expand bolts.
- Load Test: After installation and adjustments, perform a no-load test (2-3 cycles) to check for abnormal noise, leakage, and verify lifting time and height against technical parameters.
Maintenance Features:
- Cleanliness: Keep the facility clean and tidy. Avoid placing objects on or under the lift to prevent damage or injury during operation.
- Control Panel: Maintain a dry and clean control panel to prevent dust from damaging the electromagnetic valve, hydraulic oil box, and electrical components. Do not place objects on the operation panel to avoid misacting buttons or indicator lights.
- Pipelines: Keep hydraulic pressure, pneumatics, pipelines, and connections clean to prevent aging and dilapidation.
- Hydraulic Oil:
- Change hydraulic oil after 3 months of initial use. Subsequently, change it every 2 years or as usage dictates.
- Thoroughly drain used oil, clean the oil tank and filter, and refill with sufficient oil.
- Regularly check oil level and prevent dirt from entering the tank to avoid pump damage.
- Oil Filter: Clean the oil filter every 3 months using kerosene and a brush. Replace if damaged.
- Pneumatic Filter: Regularly check and clean the pneumatic two-component filter.
- Screws and Cardinal Axis: Check the status of screws for every cardinal axis every half month.
- Greasing: Add grease to every oil filling cup every half month.
- Idler Wheel and Sliding Block: Keep these moving parts clean and add grease regularly.
- Sliding Block Replacement: Change the lift sliding block annually, or more frequently if the equipment is used very often.
- Daily Cleaning: Clean the area around the lift after work each day.
