II. Product Details

Core Highlights

1. Precise Vehicle Adaptation, Strong Scenario Targeting:Specifically designed for RWD/FWD passenger cars with GVM < 2,000kg, such as mainstream models like Toyota Corolla (FWD, GVM approx. 1500kg) and Volkswagen Golf (FWD, GVM approx. 1400kg). The lifting platform and load capacity accurately match the size and weight of their transmissions, avoiding the problem of "poor adaptability of general-purpose equipment".
2. Stable and Safe, Worry-Free Operation:The main structure is made of a durable steel frame, with no obvious deformation under 500kg load. The surface is treated with anti-rust to resist workshop oil stains and dust erosion. Equipped with load control chains, it can firmly fix the transmission on the lifting platform, preventing components from sliding and tipping during lifting, and increasing the safety factor by 60%.
3. Flexible and Efficient, Reducing Labor Costs:4 swivel castors support 360° flexible steering, allowing easy position adjustment even in narrow workstations of repair shops to accurately align with the transmission bottom. The lifting platform is adjustable, enabling adaptation to different transmission chassis heights without repeatedly moving the equipment. A single person can complete transmission lifting and positioning, improving operation efficiency by 50%.
4. Strong Height Adaptability, Reducing Transfer Steps:The 820mm minimum height can reach under the vehicle chassis close to the ground without disassembling the chassis guard. The 1768mm maximum height can lift the transmission directly to the maintenance workbench (conventional height: 1.5-1.7 meters), eliminating the need for manual handling and transfer, avoiding component damage from collisions, and reducing the labor intensity of maintenance personnel.

III. Application Scenarios

1. Passenger Car Maintenance Scenario in Auto 4S Stores:Used for fault maintenance of family car transmissions, such as disassembly and assembly of Honda Civic transmissions (approx. 300kg). The 820mm minimum height reaches under the vehicle, swivel castors fine-tune the position to make the lifting platform fit the transmission, and after fixing with load control chains, it is lifted to 1700mm to be flush with the maintenance platform. Maintenance personnel can directly disassemble the transmission on the platform, improving maintenance efficiency.
2. Multi-Vehicle Maintenance Scenario in Auto Repair Shops:Maintains transmissions of different brands of FWD/RWD passenger cars, such as Nissan Sylphy (FWD, transmission approx. 280kg) and BMW 1 Series (RWD, transmission approx. 400kg). The 500kg rated capacity adapts to the transmission weights of both models, and the adjustable lifting platform adapts to different transmission bottom shapes. Maintenance of multiple vehicle models can be completed without changing tools, reducing equipment procurement costs.
3. On-Site After-Sales Service Scenario for Passenger Cars:Provides emergency transmission maintenance for users in remote areas. The equipment (52kg nett weight) can be loaded into an after-sales rescue vehicle. Upon arrival at the site, swivel castors are used to move on flat outdoor ground, and the 820mm low height adapts to the outdoor environment without fixed workstations, quickly completing transmission lifting and temporary maintenance, solving the problem of "inconvenient users traveling to repair shops".
4. Automotive Training Institution Scenario:Used for passenger car maintenance teaching to demonstrate the transmission disassembly and assembly process. The stable lifting platform and load control chains ensure safety during teaching, and the 820-1768mm height adjustment can meet the observation and operation needs of students of different heights, helping students intuitively understand the connection between the transmission and the chassis and improving teaching effectiveness.

IV. Frequently Asked Questions (FAQs)

1. The Casters Get Stuck When Moving the Device, and It Cannot Steer Flexibly. What to Do?
   • Clean Debris from Casters: Check if the gaps of the swivel castors are stuck with wire, screws, hard oil blocks, or other debris. Clean them with a brush. If oil has solidified, wipe the caster bearings and axles with a rag dipped in diesel to remove oil stains;
   • Lubricate Caster Components: Apply Grade 3 lithium-based grease to the contact area between the caster swivel axle and bearings, rotate the casters 10-15 times to ensure even lubrication, and reduce jamming caused by component friction;
   • Check Caster Wear: Inspect if the caster rubber is aged and cracked or if the axle is deformed. If severely worn, contact the manufacturer to replace the swivel castors of the same specification (it is recommended to adapt to a load capacity of ≥150kg per caster) to avoid mobility issues caused by caster problems.
2. The Lifting Platform Cannot Fit Closely to the Transmission Bottom, Resulting in Unstable Support. What to Do?
   • Adjust Platform Angle: Loosen the lifting platform adjustment bolts, fine-tune the platform tilt angle according to the transmission bottom tilt (e.g., some transmission bottoms are inclined), ensure the platform is in full contact with the transmission bottom, and then tighten the bolts to lock the position;
   • Place Buffer Pads: If there are protruding components (such as oil pipe interfaces) on the transmission bottom, place a 5mm thick rubber buffer pad (cut to fit the platform size) between the platform and the transmission to fill gaps, enhance friction, and prevent component sliding;
   • Calibrate Device Level: Use a level to check if the device is overall level. If inclined, fine-tune the adjusting feet at the bottom of the device (available on some models) or place a thin steel plate (1-2mm thick) under the lower side to ensure the lifting platform is level and the support force is even.
3. During Lifting, the Device Lifts at an Uneven Speed or suddenly Stops. What to Do?
   • Check Hydraulic System (for Hydraulic Models): For hydraulic-driven models, open the hydraulic oil tank cap and check if the hydraulic oil level is below the minimum scale. If insufficient, add 46# anti-wear hydraulic oil to the normal level; if there are bubbles in the hydraulic oil, close the lifting valve, press the lifting handle repeatedly 10-15 times, and slowly open the valve to release the bubbles until the lifting is smooth;
   • Inspect for Lifting Rod Jamming: Check if there is rust or debris between the lifting rod and the outer sleeve. Sand the rust on the lifting rod surface with sandpaper, apply lubricating oil, and lift/lower repeatedly 3-5 times to eliminate jamming;
   • Check for Overload: Confirm if the actual weight of the transmission exceeds the 500kg rated capacity. If overloaded, stop operation immediately and replace with a device with a larger load capacity to avoid damage to the lifting system caused by overload.
4. The Load Control Chains Cannot Firmly Fix the Transmission, and There Is a Risk of Slipping. What to Do?
   • Adjust Chain Length: Loosen the chain adjustment buckle, adjust the chain length according to the transmission circumference, ensure the chain is tightly attached to the transmission surface, and the buckle is fully locked into the slot (a "click" sound is heard) to avoid fixing failure caused by loose chains;
   • Check Chain Wear: Inspect if the chain links are broken or deformed, and if the chain surface is severely rusted. If the wear exceeds 10% or there are signs of breakage, contact the manufacturer to replace the load control chain of the same specification (it is recommended to have a load capacity of ≥800kg), and do not use damaged chains;
   • Add Auxiliary Fixing: If the transmission surface is smooth, wrap anti-slip cloth (such as canvas) around the contact area between the chain and the transmission to enhance friction. At the same time, ensure the chain fixing points avoid vulnerable components such as transmission oil pipes and wires to prevent crushing damage.
