FAQ and Service

We are a real factory and located in Qingdao City, China

We manufacture a comprehensive range of automotive lifting equipment to suit every workshop size and application:

Two-post lifts — asymmetric and symmetric configurations, 3,000–5,000 kg capacity, the most popular choice for general garages.
Four-post lifts — drive-on runway design, ideal for wheel alignment, storage, and long-term maintenance.
Scissor lifts — surface-mounted and in-ground models, 2,500–5,000 kg, suited for fast-turnaround service bays.
Single-post lifts — compact footprint for space-constrained shops, typically 2,000–3,000 kg.
Portable low-rise lifts — drive-on ramps for tire and brake work, no pit or permanent installation needed.
Truck / bus lifts — heavy-duty 4-post and mobile column lifts from 8,000 to 60,000 kg.
Parking lifts — single-level and double-deck parking systems for residential and commercial facilities.

Symmetric lifts position the vehicle centered between both columns. The arms on each side are equal in length. This provides stable support for heavier vehicles such as SUVs and pickup trucks, and allows technicians to walk freely around the rear of the car.

Asymmetric lifts rotate the columns outward approximately 30°, so the vehicle is positioned closer to the front. This design allows the car door to open nearly 90° when the vehicle is elevated — essential for servicing modern cars with large doors in tight bays.

Yes. Our in-ground scissor lifts are engineered for flush-floor installations, giving a clean, unobstructed workshop appearance. We offer single-scissor and double-scissor (parallel scissors) configurations with capacities from 2,500 kg to 5,000 kg.

Key features include: hydraulic power with anti-explosion valve, stainless steel hydraulic cylinder, and surface-hardened scissor steel for corrosion resistance. We provide full pit drawings and structural load calculations to assist your civil contractor.

Absolutely. Our four-post drive-on lifts are dual-purpose: at full height they serve as a second-level parking space, while at a mid-position they allow comfortable undercar access for oil changes, exhaust work, and inspections.

Optional accessories that enhance this dual use include: rolling bridge jack (allowing individual wheel lift for alignment), slip plates, turntable sets, and side-step extensions for wider vehicles. All accessories are pre-engineered at the factory and attach without field drilling.

Yes. Our mobile column lifts (also called wireless mobile column lifts) are designed for commercial vehicles, agricultural equipment, and defense vehicles. Each column is battery-powered with a built-in wireless synchronization module, so there are no trailing cables across the workshop floor.

Yes. Our four-post alignment lifts are a popular choice for wheel alignment workshops worldwide. Standard configuration includes:

· Drive-on runways with rolled anti-slip surface treatment
· Rear slip plates (fore-aft and lateral movement, stainless steel surface) — allows rear axle to move freely during alignment
· Front turntables (360° rotation, ± 30° steering lock) — fits into recesses in the drive-on runways
· Rolling bridge jack (2,000 kg capacity) — lifts individual axles for wheel removal during alignment
· Side extenders for wide-track vehicles

We supply alignment lifts that are mechanically compatible with all major wheel alignment machine brands (Hunter, Hofmann, Corghi, Snap-on, John Bean) — simply confirm your alignment machine brand and we verify fit before production.

Yes — our residential and light commercial parking lifts are popular in space-constrained markets such as Japan, Singapore, South Korea, and European city apartments. We offer:

Two-post elevated parking platform: A single-level elevated deck for one car, freeing the space underneath for a second vehicle. Capacity 2,500–3,500 kg. Lift height: 1,800–2,000 mm. Operating noise: < 65 dB(A).

Single-scissor residential lift: Ultra-compact footprint, surface-mounted, ideal for single-car garages that need undercar access without a pit.

Residential models include: key switch (child safety), low-speed motor for quiet operation, weatherproof coating for outdoor use, and optional rain canopy kit. These units can be powered from a standard single-phase 220–240V household circuit.

Always select a lift whose rated capacity exceeds the heaviest vehicle you will regularly service by at least 20–25%. Operating a lift at its absolute maximum rating shortens service life and compromises safety.

If you are unsure, share your vehicle make/model list with us and we will confirm the correct capacity and arm configuration in writing before you place an order.

Lift height and arm reach are critical for both technician comfort and vehicle compatibility. Our standard two-post lifts offer:

Four-post runway lengths range from 4,200 mm to 5,500 mm to accommodate vehicles from compact city cars to full-size American trucks and European long-wheelbase SUVs. Custom runway lengths are available.

This is one of the most important pre-installation questions. Our requirements align with industry-standard engineering practice:

We provide a detailed installation checklist with every shipment. If your floor does not meet these requirements, we can recommend an alternative lift type (such as a runway-style four-post) that distributes the load over a larger area.

Yes — we customize the power unit for every export order. Our standard configurations include:

Simply specify your local supply voltage and frequency when placing your order. We configure the motor, capacitors, and control board before shipment at no extra charge. A voltage/frequency label is affixed to each unit for your electrician.

Our standard two-post lifts reach full elevation (approximately 1,900 mm) in 45 to 60 seconds under a 2,000 kg load. Lowering speed is controlled by an adjustable descent valve and typically takes 50–70 seconds for a smooth, controlled descent.

These times reflect real-world throughput: a busy shop can comfortably complete a lift cycle (up, work, down) in under 30 minutes for routine services, which is consistent with international benchmarks for four-bay productivity.

Yes, and this is a question we receive increasingly often. There are two considerations specific to EVs:

1. Weight: Modern EVs are significantly heavier than equivalent ICE vehicles due to battery packs. A Tesla Model Y, for example, weighs approximately 2,100 kg. We recommend a minimum 4,000 kg capacity for EV service lifts.

2. Battery pack clearance: EV battery packs are mounted flat under the floor. Arm pad positions must avoid the battery tray. We supply a multi-point rubber pad set with EV-safe adapter plates that contact only the designated pinch-weld or frame contact points.

Our lift columns are fabricated from Q345B structural steel (equivalent to ASTM A572 Grade 50 or EN S355), a high-strength low-alloy steel with excellent weld characteristics and fatigue resistance — the same grade used in bridge and structural construction.

Surface treatment process:

1. Shot blasting: Steel surfaces are shot-blasted to Sa 2.5 standard (near-white metal), removing all mill scale, rust, and contamination.
2. Primer: Two-component epoxy primer (40–60 μm dry film thickness).
3. Topcoat: Polyurethane powder coat or two-pack polyurethane liquid paint (60–80 μm), available in standard gray (RAL 7035) or custom RAL color.
4. Salt spray test: Finished columns pass a 500-hour salt spray test per ISO 9227 — documented in our QC records.

Our two-post lifts use one of two equalization systems depending on model series:

Wire rope (cable) equalization: 6×19 fiber-core galvanized steel wire rope, minimum breaking strength 4× the design load. Cables are pre-lubricated and run on sealed sheave bearings. Expected service life: 5–8 years under normal workshop conditions (10–15 cycles per day).

Roller chain equalization: ISO-standard #50 or #60 pitch roller chain with a minimum 4:1 safety factor on breaking load. Self-lubricating chain is available as an upgrade. Expected service life: 8–12 years.

We recommend inspecting cables/chains monthly and replacing when elongation exceeds 3% of the original pitch length, or when any broken wire strands or corrosion pitting is visible.

Yes, with consideration for the specific installation environment. In EV fast-charge bays, the primary concerns are:

Electromagnetic compatibility (EMC): Our power units are shielded and comply with CE EMC Directive 2014/30/EU, meaning they will not interfere with nearby charging equipment electronics.

Trench / cable management: We offer a fully concealed hydraulic line routing option (lines run inside the column profile) to avoid trip hazards and conflict with charging cable management systems in the bay.

Ventilation: EV batteries that are damaged can off-gas. We recommend ensuring the workshop has compliant ventilation per local fire safety standards when servicing EVs — this is independent of the lift itself but is part of the safe service bay design.
