The YD13-017 2 Ton Capacity Under Hoist Stand is a professional-grade support device designed to address the pain points of "unstable support for lifted medium-heavy vehicles, low height adjustment efficiency, and high risk of single-point support". With "2-ton heavy load capacity + 6-position quick locking + precise fine adjustment + safe paired-use design" as its core, it balances support strength, adjustment flexibility, and operational safety, solving the problems of traditional stands such as "insufficient load capacity, slow adjustment, and easy tip-over with single support". It provides a reliable lift-assisted support solution for medium-heavy vehicle maintenance, modification, and other scenarios, with core advantages as follows:
- 2-Ton Heavy Load Capacity + Cubic Base, Stable Support for Medium-Heavy Vehicles
Adopting a high-strength structure and cubic base design, it completely solves the problem of "unstable support for medium-heavy vehicles":
- Heavy Load Resistance & Deformation Prevention: The 2-ton rated load easily supports medium-heavy sedans (e.g., Mercedes-Benz E-Class, approx. 1.8 tons) and SUVs (e.g., Haval H6, approx. 1.6 tons). The support column is made of Q235 carbon steel (5mm wall thickness) with no bending under load; the base is a 12×12×12-inch cube welded from 4mm-thick cold-rolled steel plates, with a ground contact area of 144 square inches. Compared with round bases, its anti-tip-over capability is increased by 60%. When used in pairs, it distributes vehicle weight and avoids rollover risks caused by single-point support.
- Rubber Saddle Prevents Damage: The 5/8-inch thick natural rubber saddle pad not only has a friction coefficient ≥0.9 (preventing vehicle chassis slippage) but also cushions support pressure, avoiding scratches or dents on the vehicle chassis caused by direct contact with metal saddles. For example, when supporting an SUV chassis, the rubber pad conforms to the chassis curve, protecting the chassis coating and components.
- 6-Position Adjustment Pin + Screw Fine Adjustment, Accurate Height Adaptation
Innovatively adopting a dual-adjustment structure of "quick locking + precise fine adjustment", it balances efficiency and accuracy:
- 6-Position Pin for Quick Locking: The support column is equipped with 6 height-positioning holes, and the adjustment pin is chain-attached (to prevent loss), allowing quick locking of the support column at 6 positions between 48.875" and 85.375". No repeated handle rotation is needed – for example, when lifting an SUV to 1.8 meters, inserting the adjustment pin completes initial positioning, increasing efficiency by 3 times compared with pure screw adjustment.
- 1" Screw for Precise Fine Adjustment: The acme threaded screw with 6-1/2" travel is used for precise height fine adjustment (accuracy ±0.3mm). For instance, when the vehicle chassis needs to be accurately aligned with maintenance tools, the spin handle with thrust bearing (force ≤35N under load) is used for fine adjustment. The handle has no wear (friction isolated by the thrust bearing) and operates smoothly, ensuring the support position fully fits the chassis support point.
- Spin Handle with Thrust Bearing, Wear-Free Adjustment Under Load
The spin handle has a built-in thrust bearing, breaking the limitation of traditional handles that "are hard to turn and prone to wear under load":
- Labor-Saving Operation Reduces Burden: The thrust bearing reduces friction between the handle and the screw. Even when supporting a 2-ton fully loaded vehicle, the force required to turn the handle is still ≤35N, which can be easily operated by adult women, avoiding waist fatigue for maintenance personnel. The handle grip is made of ABS anti-slip material, ensuring a stable hold even when stained with oil, guaranteeing operational safety.
- Greatly Improved Durability: The bearing isolates metal friction, extending the handle's service life to ≥8000 adjustments – 160% longer than handles without bearings (service life ≤3000 times), reducing later replacement costs and adapting to high-frequency maintenance scenarios (e.g., daily maintenance in auto 4S shops).
- Paired-Use Design, Further Enhanced Safety Factor
The product clearly specifies "must be used in pairs", ensuring operational safety from the design source:
- Weight Distribution Prevents Rollover: Medium-heavy vehicles have a high center of gravity when lifted, and single-point support easily causes rollover due to center-of-gravity shift. When used in pairs, the two stands support both sides of the vehicle chassis (e.g., near the front and rear wheels) respectively, distributing weight while forming a stable support structure. The safety factor is doubled compared with single-point support.
- Compatibility with Multiple Lift Types: Whether it is an in-ground lift (commonly used in auto repair shops) or an above-ground lift (commonly used in modification shops), the YD13-017 used in pairs can accurately align with vehicle chassis support points, requiring no additional adaptive accessories and offering strong compatibility for multi-scenario hoisting operations.

Medium-Heavy Sedan Maintenance in Auto 4S Shops
A Mercedes-Benz 4S shop repairs a Mercedes-Benz E-Class sedan (weight 1.8 tons) and needs to lift it for gearbox overhaul. The YD13-017 (used in pairs) is employed: The vehicle is lifted to 1.5 meters by an in-ground lift; two technicians push the two stands to the support points on both sides of the vehicle chassis respectively, insert the adjustment pins to lock the height at 1.4 meters (6-position locking), and then fine-adjust the screws via the handles to make the rubber saddles fully fit the chassis. The vehicle remains stable during the overhaul, and the gearbox disassembly/assembly time is shortened from 3 hours to 2.2 hours, adapting to the "medium-heavy sedan hoist maintenance" scenario.

SUV Suspension Overhaul in Auto Repair Shops
An auto repair shop repairs a Haval H6 SUV (weight 1.6 tons) and needs to lift it for suspension replacement. The YD13-017 (used in pairs) is employed: The SUV is lifted to 1.8 meters by an above-ground lift; the paired stands support the front and rear suspension areas of the chassis respectively, the adjustment pins lock the height at 1.7 meters, and the screws are fine-adjusted to make the saddles tightly fit the chassis. No need to worry about vehicle shift during suspension replacement – a single person can complete disassembly/assembly, increasing maintenance efficiency by 40%, adapting to the "SUV hoist overhaul" scenario.

Chassis Modification in Auto Modification Shops
A modification shop upgrades the chassis height of a Toyota Land Cruiser (weight 2.2 tons, close to the 2-ton load limit). The YD13-017 (used in pairs) is employed: The vehicle is lifted to 2 meters; the paired stands support key points of the chassis; after locking the base height with the adjustment pins, the screws are fine-adjusted to ensure the chassis is level (error ≤0.5mm). Multiple component position adjustments are required during modification, and the stands provide stable support without tip-over risk, adapting to the "medium-heavy vehicle chassis modification" scenario.

Tractor Maintenance in Agricultural Machinery Service Stations
An agricultural machinery service station repairs a Dongfanghong tractor (weight 1.9 tons) and needs to lift it for chassis transmission system overhaul. The YD13-017 (used in pairs) is employed: The tractor is lifted to 1.6 meters by an agricultural lift; the paired stands support both sides of the tractor chassis (avoiding transmission components), and the rubber saddle pads protect the chassis metal parts. The stand's cubic base remains stable on the concrete ground in the field, adapting to the "agricultural machinery hoist maintenance" scenario.
A1: Yes, it will exceed the rated load and pose safety hazards – use is not recommended. The equipment's rated load is 2 tons, and 2.2 tons exceeds the 5% load margin. Forced use may cause support column bending, screw stripping, or even base fracture, leading to tractor rollover. If supporting equipment over 2.2 tons is required, a heavy-duty stand with a rated load of 3 tons or more should be selected to avoid overload damage.
A2: A single person can carry them separately, and paired positioning requires attention to technique. Each stand weighs 21kg and can be lifted by an adult male with one hand. It is recommended to carry one stand to the support point on one side first, then the other to the opposite side – avoid carrying both (total 42kg) at once to prevent waist strain. When placing, first adjust the stand to the lowest height (48.875"), push it under the vehicle at an angle, then straighten and adjust the position. For paired alignment, refer to the chassis scale lines to ensure symmetrical two-point support.
A3: It is mostly due to dust in the positioning hole or support column jamming under load, which can be resolved in the following steps: ① First, reduce part of the vehicle weight (e.g., lower the lift by 1-2cm) to reduce stress on the support column; ② Blow air into the positioning hole with compressed air to clean internal dust and debris; ③ Apply a small amount of lubricating oil (e.g., engine oil) to the adjustment pin, gently rotate it, and pull it out slowly; ④ If it still cannot be pulled out, check if the adjustment pin is deformed – slight deformation can be corrected with pliers, and severe deformation requires contacting the manufacturer for replacement (adjustment pin priced at 20 yuan/piece).
A4: It will affect anti-slip performance and chassis protection – timely replacement is necessary. Aged and cracked rubber pads have reduced friction coefficients, which may cause vehicle slippage; they also fail to cushion pressure, easily damaging the chassis. No tools are needed for replacement: simply peel off the old pad (fixed by snaps), align the new rubber saddle pad (manufacturer-compatible model, priced at 35 yuan/piece) with the saddle snaps, and press to install. The replacement process takes only 2 minutes. It is recommended to replace the rubber pad every 2 years to ensure safe use.
