I. Product Specifications

II. Product Details

Core Highlights

1. Wide Platform, Upgraded Adaptability:The 340×240mm lifting platform is wider than conventional models, and can directly adapt to passenger car transmissions with protruding structures (such as oil pipe interfaces and bottom brackets) without additional gaskets or component position adjustments. The coverage of applicable vehicle models is 30% higher than that of narrow-platform models, reducing preparation time before maintenance.
2. Safe and Durable, Reducing Maintenance Costs:The main body is made of Q235 high-hardness steel frame, with a phosphating anti-rust treatment on the surface, which can resist oil stains and dust erosion in the workshop. It passes a 48-hour salt spray test, and its service life is 50% longer than that of ordinary carbon steel materials. The load control chain is made of manganese steel with a tensile strength of 800MPa, which can firmly fix the transmission even if the equipment shakes slightly during lifting, avoiding component damage due to slipping.
3. Flexible and Efficient, Saving Manpower:4 swivel castors support 360° unrestricted steering, allowing easy position adjustment in narrow workshop workstations (such as multi-vehicle side-by-side maintenance and equipment-dense areas) to accurately align with the transmission bottom. The height of the lifting platform can be quickly adjusted via a handle, and a single person can complete the full process of "alignment - fixation - lifting", which improves operation efficiency by 50% compared with the traditional two-person cooperation mode.
4. Lightweight Design, Wide Scene Adaptation:With a nett weight of 52kg, it is easy to move in the repair shop and can also be loaded into after-sales rescue vehicles for on-site services. The 820-1768mm height range covers the chassis heights of mainstream passenger cars (such as Toyota Camry) and compact SUVs (such as Honda CR-V). One device can meet the maintenance needs of multiple vehicle models, reducing equipment procurement costs.

III. Application Scenarios

1. Passenger Car Maintenance Scenario in Auto 4S Stores:Used for fault maintenance of family car transmissions, such as the disassembly and assembly of transmissions for Volkswagen Magotan (transmission weight: approx. 350kg) and Toyota Avalon (transmission weight: approx. 320kg). The 820mm height reaches under the vehicle, swivel castors fine-tune the position to make the 340×240mm platform fit the transmission bottom. 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 workbench, avoiding component damage caused by manual handling.
2. Multi-Vehicle Maintenance Scenario in Comprehensive Auto Repair Shops:Maintains transmissions of passenger cars of different brands and models, such as Nissan Teana (transmission: approx. 300kg) and Buick LaCrosse (transmission: approx. 400kg). The 500kg safe working capacity and wide platform adapt to both models, enabling disassembly and assembly without replacing equipment. This reduces the idle rate of equipment in repair shops and improves workstation utilization (each workstation can maintain 1-2 more vehicles per day).
3. On-Site After-Sales Service Scenario for Passenger Cars:Provides emergency transmission maintenance for users in remote areas (such as temporary disassembly and inspection for transmission oil leakage and abnormal noise). The device (52kg) can be loaded into the trunk of an after-sales rescue vehicle. Upon arrival at the site, swivel castors move flexibly on flat outdoor ground, and the 820mm height adapts to the outdoor environment without fixed workstations, enabling quick lifting and inspection of the transmission and solving the inconvenience of users traveling to repair shops.
4. Automotive Vocational Training Scenario:Used for passenger car maintenance teaching (such as demonstrating the connection between the transmission and the chassis, and teaching the disassembly and assembly process). The wide platform allows students to observe the bottom structure of the transmission; the load control chain ensures safety during teaching (avoiding component slipping caused by students' incorrect operations); the 820-1768mm height adjustment can meet the operation needs of students of different heights, helping students quickly master transmission disassembly and assembly skills.

IV. Frequently Asked Questions (FAQs)

1. The swivel castors get stuck when moving the device, and it cannot steer flexibly. What should I do?
   • Clean and Lubricate: First, check if the gaps of the castors are stuck with wire, screws, or hard oil blocks. Clean them with a brush, then wipe the caster bearings with a rag dipped in diesel. Then apply Grade 3 lithium-based grease to the contact area between the bearings and the axle, and rotate the castors repeatedly 10-15 times to ensure even lubrication and relieve jamming.
   • Check Caster Status: If jamming persists after cleaning and lubrication, check 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 that the load capacity of a single caster is ≥150kg) to avoid mobility issues caused by caster faults.
2. The lifting platform cannot fit closely to the transmission bottom, resulting in unstable support. What should I do?
   • Adjust Platform Angle: Loosen the adjustment bolts on the side of the lifting platform, fine-tune the platform tilt angle according to the tilt of the transmission bottom (for example, the bottom of some transmissions is inclined), and tighten the bolts to lock the position after ensuring the platform is in full contact with the transmission bottom.
   • Add Anti-Slip Pads: If there are protruding components on the transmission bottom causing local suspension, place a 5mm-thick rubber anti-slip pad (cut to a suitable shape) at the contact area between the platform and the components to fill gaps and enhance friction, preventing component slipping.
3. During lifting, the device lifts at an uneven speed or suddenly stops. What should I do?
   • Check the Hydraulic System (for Hydraulic Models): For hydraulic-driven models, open the hydraulic oil tank cap and confirm if the hydraulic oil level is below the minimum scale. If insufficient, add 46# anti-wear hydraulic oil. If there are bubbles in the hydraulic oil, close the lifting valve, press the lifting handle repeatedly 10-15 times, then slowly open the valve to release the bubbles until the lifting speed returns to normal.
   • 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 surface of the lifting rod with sandpaper, apply lubricating oil, and lift/lower repeatedly 3-5 times to eliminate jamming (do not press the handle forcefully to avoid damage to the hydraulic system).
4. The load control chain cannot firmly fix the transmission, and there is a risk of slipping. What should I do?
   • Adjust Chain Length: Loosen the chain adjustment buckle, shorten the chain according to the circumference of the transmission, ensure the chain is tightly attached to the transmission surface, and the buckle is fully locked into the slot (a "click" locking sound is heard) to avoid fixation failure due to loose chains.
   • Check Chain Wear: Check 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, immediately contact the manufacturer to replace the manganese steel chain of the same specification (it is recommended that the load capacity is ≥800kg), and do not use damaged chains.
   • Auxiliary Anti-Slip Treatment: If the transmission surface is smooth, wrap a layer of canvas around the contact area between the chain and the transmission to enhance friction. At the same time, ensure the chain fixation points avoid vulnerable components such as transmission oil pipes and wires to prevent crushing damage.
