The YD03-004 500kg Dual Hook Engine Support Bar is a tool designed specifically for "in-place support during automotive engine maintenance". Addressing the pain points of traditional support tools such as "poor stability, few applicable models, and easy body damage", it takes the dual hook balanced structure and flexible protection design as the core to achieve the core needs of "multi-model adaptation, safe load-bearing, and non-destructive operation". It is suitable for auto repair shops, auto maintenance stores, and individual heavy-duty auto repair scenarios. Its core advantages are as follows:
- 500kg High Load-Bearing + Dual Hook Balance, Stable Support Without Shaking:The crossbar frame is made of Q235 low-carbon steel with a tensile strength of 375MPa, and the frame deformation is ≤0.3mm under 500kg load; equipped with a dual hook balanced support assembly, the distance between the two hooks can be adjusted synchronously with the crossbar extension, which can evenly distribute the weight of the engine/transmission (such as 200-500kg engines of family cars/commercial vehicles), avoiding support tilt caused by single-point force. Compared with single-hook support tools, the stability is increased by 80%, and there is no risk of engine displacement during maintenance.
- 1020-1630mm Telescopic Adjustment, Full Coverage of Multi-Models:The crossbar supports 1020-1630mm free length adjustment, fixed by a knob-type lock — adjust to 1020-1200mm for small sedans (e.g., Honda Fit, Toyota Vios), 1200-1400mm for compact SUVs (e.g., Volkswagen Tharu, Honda CR-V), and 1400-1630mm for medium-to-large sedans (e.g., Audi A6L, BMW 5 Series). The model adaptation rate is over 95%, and one unit can meet the needs of most household and commercial vehicles.
- Extra-Long Rubber Cushioned Legs, Anti-Paint Damage:The support legs adopt an extra-long design (length about 200mm), with the bottom wrapped in a 15mm thick rubber cushion layer, and the contact area with the vehicle body reaches 120cm². It can not only increase friction (friction coefficient ≥0.85) to prevent the support bar from sliding, but also avoid direct metal contact with the vehicle body, eliminating scratches or dents on the bonnet and fender paint; even if the support legs accidentally collide with the vehicle body, the rubber layer can buffer the impact force, especially suitable for paint protection needs of high-end models.
- Leveling Screws + High-Gloss Enamel, Precise and Durable:Equipped with 4 leveling adjustment screws, which can fine-tune the support height (adjustment range 0-20mm) by rotating clockwise/counterclockwise, ensuring the engine remains horizontal during maintenance (e.g., the engine needs to be level for gearbox disassembly), avoiding component disassembly jams caused by tilt; the crossbar surface is treated with high-gloss enamel coating, with a thickness of 60μm, oil-resistant and corrosion-resistant, no rust even in long-term contact with engine oil stains, and the service life is 2.5 times longer than ordinary painted tools.
- Engine Overhaul in Auto Repair Shops:When repair shops conduct engine overhauls (e.g., piston replacement, cylinder block maintenance) for family sedans (e.g., Volkswagen Lavida, Nissan Sylphy), mount the support bar across both sides of the bonnet, adjust the length to 1020-1400mm, hook the dual hooks to the engine lifting points, and stably support with 500kg load; the rubber legs protect the vehicle body paint, and the leveling screws ensure the engine is horizontal, facilitating technicians to disassemble engine accessories, adapting to the needs of "efficient overhaul and non-destructive operation".
- Transmission In-Place Maintenance in Auto Maintenance Stores:When auto maintenance stores repair transmissions for SUVs (e.g., Haval H6, Changan CS75), there is no need to disassemble the engine. Use the support bar's dual hooks to hook the transmission lifting lugs, and the maximum 1630mm length can be cross-mounted on the bonnet of wide-body models. The 500kg load stably fixes the transmission in place, avoiding transmission falling during maintenance; the adjustment screws fine-tune the height to ensure the transmission is aligned with the engine interface, reducing maintenance difficulty and improving operation efficiency.
- Engine Maintenance by Individual Auto Repair Enthusiasts:When individuals perform in-depth maintenance (e.g., oil pan cleaning, timing chain inspection) on 4-cylinder family cars (e.g., Toyota Corolla, Honda Civic), the minimum 1020mm length adapts to compact vehicle bodies, and the 23kg lightweight design is convenient for single-person carrying and assembly; the rubber legs avoid scratching the paint of their own vehicles, and the dual hooks support the engine stably, solving the pain point of "no professional support tools for individual maintenance".
- Component Fixation in Auto Modification Shops:When modification shops replace high-performance intake manifolds and turbochargers for vehicles, temporary engine support is needed to avoid displacement. The support bar's dual hooks can flexibly hook different lifting points of the engine, and the 1020-1630mm length adapts to the modified vehicle body size; the high-gloss enamel coating is resistant to scratches from metal debris during modification, adapting to the needs of "flexible support and modification scenario adaptation".
A1:Yes. 450kg does not exceed the 500kg safe load, and the product reserves a 10% safety margin (the actual safe load is about 550kg). When in use, the dual hooks should be hooked to the symmetrical lifting points on both sides of the engine to ensure even weight distribution; adjust the crossbar length to match the bonnet width of the model (1400-1630mm is recommended), then use the leveling screws to level the engine to avoid excessive force on one side, which fully meets the support needs of V6 engines.
A2:It can be used with standard lifting chains (chains with load-bearing ≥500kg and link diameter ≥8mm are recommended). The connection steps are simple: ① Hang one end of the chain on the engine lifting point (most models have dedicated lifting rings for the engine); ② Hang the other end of the chain on the support bar's hook, ensuring the hook is closed and locked; ③ Adjust the length of the two chains to be consistent to balance the engine force; if the engine has no lifting points, a dedicated engine lifting plate (sold separately) can be used with the chain to ensure a stable connection.
A3:Yes. The bonnet width of 7-seater MPVs such as Buick GL8 is about 1500-1550mm, and the maximum 1630mm length of the support bar can fully cover it; when in use, extend the crossbar to 1500-1550mm, fix the length with the lock buckle, place the support legs on the reinforcing ribs on both sides of the bonnet (avoid pressing on weak paint), and hook the dual hooks to the engine lifting points to achieve stable support, adapting to the needs of most MPV models.
A4:Jamming is mostly caused by oil or debris blockage. The handling steps are: ① Unscrew the adjustment screws counterclockwise, and clean the oil stains in the screw threads and screw holes with kerosene or diesel; ② Gently polish the screw threads with fine sandpaper (avoid excessive wear) to remove rust or burrs; ③ Apply lithium-based grease (temperature-resistant -20℃-60℃) on the threads, screw back into the screw holes clockwise and rotate repeatedly 3-5 times, and the jamming phenomenon can be eliminated without professional maintenance.
