1. Full Coverage of 10-Grade Loads, No Gap Between Light and Heavy Scenarios

• Lightweight Portable Models (2-4T: YD17-001~002) – First Choice for Individual Car Owners' Emergencies
  YD17-001 (2T) weighs only 2.2kg (equivalent to the weight of two 1L bottles of mineral water), with an ultra-low minimum height of 150mm that can be extended under low-chassis cars (e.g., BMW 3 Series, Audi A4L). The detachable two-piece handle can be stored with the jack in the car's side storage compartment after disassembly, suitable for outdoor emergency tire replacement; YD17-002 (3-4T) is upgraded to 3-4Ton capacity, capable of lifting small SUVs (e.g., Haval M6, Changan CS35). With a weight of 2.8kg, it can still be carried with one hand, and its applicable scenarios are expanded by 30% compared with the 2T model, meeting the needs of multi-vehicle families.
• Medium Practical Models (5-16T: YD17-003~007) – Core Tools for Auto Repair Shops and Small Equipment
  Covering medium loads of 5-16Ton, they are suitable for lifting light trucks (e.g., Wuling Rongguang Mini Truck) and small engineering equipment (e.g., 1-ton generators). For example, YD17-005 (10T) has a lifting height of 125mm, which can easily lift the chassis of a light truck to leave a maintenance space of more than 10cm; the notched saddle can firmly clamp the truck's chassis beam to avoid horizontal sliding; the two-piece handle can be adjusted in assembly length according to the operation space, allowing flexible force application even under the narrow chassis of a truck, with an operation efficiency 40% higher than that of one-piece handles.
• Heavy-Duty Models (20-50T: YD17-008~010) – Exclusive for Engineering and Heavy Equipment
  The 20-50Ton super load capacity is suitable for lifting heavy trucks (e.g., Foton Ollin) and large engineering equipment (e.g., small loaders). As the top model in the series, YD17-010 (50T) adopts a 60# thick-walled cylinder (with 50MPa high-pressure resistance) and an 8mm thickened base (with reinforcing ribs). When lifting 50Ton equipment, the radial expansion of the cylinder is ≤0.3mm and the base settlement is ≤0.5mm, with stability 60% higher than that of ordinary 50Ton jacks; the 19kg weight is achieved through lightweight alloy materials and structural optimization, with 25% higher mobility than similar products on the market (mostly over 25kg). The anti-slip pattern at the bottom increases the friction coefficient to 0.8 when lifting on wet ground, with no risk of rollover.

2. Triple Safety Protection, No Worries in Heavy-Load Operations

• Unique Overload Protection: Prevent Overload, Avoid Bursting
  A precision overload protection valve is built-in. When the load exceeds 10% of the rated capacity, it automatically cuts off the hydraulic oil circuit and stops the ram from extending. For example, when using YD17-010 (50T) to lift 55Ton equipment, the protection valve is activated instantly to prevent the cylinder from bursting due to excessive pressure; compared with traditional jacks without protection, the safety factor is doubled, especially suitable for temporary emergencies and scenarios with inaccurate load estimation.
• Large Base + Notched Saddle: Anti-Slip, Stable as a Rock
  The base area of all models is 25% larger than that of ordinary jacks. The base of 30-50T models reaches 320×220mm (YD17-009) and 350×250mm (YD17-010), ensuring a more stable center of gravity during lifting, even on slightly inclined ground (slope ≤3°); the saddle is designed with anti-slip grooves, which can be embedded into the surface of the lifted object (e.g., vehicle chassis beam, equipment support boss) during lifting, increasing the horizontal anti-slip force by 90% and avoiding sliding risks when lifting smooth surfaces.
• High-Strength Material: Resist Heavy Loads, No Deformation After Long-Term Use
  The cylinders of medium-high load models are made of thick-walled seamless steel pipes. For example, the cylinder wall thickness of YD17-010 is 15mm, with a tensile strength ≥1200MPa and no permanent deformation under 50Ton load; the base reinforcing rib design increases the load-bearing capacity by 50%, with no depression of the base when lifting 32Ton equipment; the anti-rust treatment (electrostatic spraying + chrome plating) can pass the 180-hour salt spray test, with no rust during long-term outdoor use, and the service life is twice that of ordinary jacks.

3. User-Friendly Operation Details, Labor-Saving and Space-Saving

• Two-Piece Handle: Disassemble for Space-Saving Storage, Assemble for Flexible Operation
  The handle can be disassembled into two sections, with a length of 180mm after disassembly (e.g., the handle of YD17-001), which can be stored in a small toolbox together with the jack; after assembly, the length is 350-400mm, adapting to the force habits of people of different heights. When held with both hands, the operating force can be distributed, saving 30% more effort than one-piece short handles; only one section of the handle can be installed for operation in narrow spaces (e.g., under the truck chassis) to avoid collision.
• Reasonable Height Design: Extendable at Low Height, Liftable at High Height
  The minimum height of light models is 150mm (YD17-001), which can be extended under sports cars with a chassis height of 120mm (e.g., Porsche 718) with the help of thin gaskets; the lifting height of heavy models reaches 145mm (YD17-009), which can leave sufficient maintenance space after lifting. For example, when maintaining the gearbox of a heavy truck, there is no need to work in a hunched position, improving maintenance comfort and efficiency.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Individual Car Owner's Outdoor Emergency Tire Replacement for Family Cars (YD17-001)

1. Take YD17-001 (2T) from the trunk, carry it to the bottom of the car with one hand (2.2kg), and quickly assemble the two-piece handle;
2. Adjust the jack position, extend the 150mm minimum height under the chassis easily, and align the notched saddle with the chassis support point;
3. Press the handle to lift – the 80mm lifting height lifts the tire 5cm off the ground, and the overload protection system monitors the load (1.5Ton ＜ 2.2Ton threshold) to ensure safety;
4. Complete the tire replacement in 10 minutes, retract the ram after pressure relief, disassemble the handle, and put it back into the trunk. No other assistance is needed throughout the process;
   Result: Compared with the simple jack equipped with the original car (no protection, laborious operation), the tire replacement time is reduced by 50%, and there is no overload risk, allowing individual car owners to complete the operation independently.

2. Chassis Maintenance of Light Trucks in Auto Repair Shops (YD17-005)

1. Select YD17-005 (10T), carry the 5.4kg tool to the bottom of the truck, and the 205mm minimum height is compatible with the truck's chassis gap (220mm);
2. Align the notched saddle with the chassis beam, press the handle to lift – the 125mm lifting height lifts the chassis 12cm off the ground, meeting the maintenance space requirement;
3. During the oil pipe replacement by maintenance personnel, the jack shows no shaking or sliding, and the whole process takes 30 minutes; open the pressure relief valve after completion, and the ram retracts slowly;
   Result: The large base and notched saddle ensure stability. Compared with ordinary jacks (prone to sliding), the maintenance safety is improved, and the operating force is ≤45N, so maintenance personnel do not feel obvious fatigue during long-term operations.
