AUTOOL ATL-4D 4000kg ATL-4.5D ATL-4.5DW ATL-4.5DA 4500kg Two Post Lift

Core Technology | Precision Manufacturing, Solid Foundation:

AUTOOL crafts the two-post lift’s main structure from laser‑precision steel plates. This process ensures tight dimensional accuracy and seamless assembly. We shot blast and high-temperature coat all steel parts after welding to create a durable, corrosion- and scratch-resistant finish.

• Core System | Precision Drive, Enduring Performance: The equipment lifts loads using a chainless dual-cylinder direct-drive hydraulic system and a synchronized steel cable balance mechanism. This integrated design ensures exceptionally smooth, stable, and synchronized operation throughout the lifting process. By replacing chains with hydraulic cylinders for direct force transfer, the system avoids wear and failure risks, improving safety, durability, and long-term reliability.
• Precision Cylinders: We machine key hydraulic cylinder parts with fully automated CNC lathes to ensure precise coaxial alignment and a smooth surface finish. The inner walls of the cylinder barrels undergo a roller burnishing process, significantly reducing friction and wear during piston movement. This contributes to quieter operation and extends the service life of the hydraulic system.
• Critical Sealing: We fit all key hydraulic sealing points with high-performance Japanese or Italian seals. These seals maintain reliable performance under long-term high-pressure and frequent cycling conditions, effectively preventing oil leakage.
• Wear-Resistant Design: The column guide sections are equipped with polymer composite wear-resistant slide blocks. This self-lubricating material effectively reduces metal-to-metal friction, minimizes operational noise during long-term load lifting, and simplifies future maintenance tasks.

Safety Design | Logical Control, Mechanical Assurance:

• Unilateral Synchronization Control: Operators only need to work from either column side to simultaneously control and release the mechanical safety locks on both sides. This design simplifies operational steps and fundamentally eliminates the risk of vehicle tilting caused by single-sided misoperation or unsynchronized unlocking.
• Multiple Mechanical Locking: The equipment is equipped with robust rack‑and‑pinion mechanical locking devices interlocked with the electrical system. At any set height, the mechanical lock backs up the hydraulics, providing stable, reliable protection for people working under the vehicle.

Advantages of different models:

• The AUTOOL ATL-4.5D is superior to the ATL-4 model: The ATL-4.5D has a lifting capacity that is 500kg greater than that of the ATL-4D (reaching 4500kg), which can more easily handle heavy vehicles such as large SUVs and commercial trucks, expanding the range of applicable vehicle models and providing more reliable and ample load safety protection.
• AUTOOL ATL-4.5DW, ATL-4.5DA, and ATL-4.5D two-post lifts are superior to the basic ATL-4D model: Extended Carriage Design—-The equipment features an extended carriage with a structural length of 1.95 meters, increasing both its length and self-weight by approximately 50% compared to standard models. This design enlarges the support base and increases counterweight, significantly improving stability and resistance to overturning. It provides a sturdier and more stable rigid platform foundation for heavy-duty vehicle lifting operations.
• The AUTOOL ATL-4.5DW two-post lift is superior to the ATL-4.5D model: the widened design (inner pillar width increased from 2860mm to 3000mm) not only significantly improves the adaptability of SUVs, MPVs and commercial trucks while maintaining a lifting capacity of 4500kg, but also provides a more spacious and safer space for working under vehicles. It can meet the needs of multiple vehicle types and achieve a balance between stability and efficiency.
• The AUTOOL ATL-4.5DA two-post lift is superior to the ATL-4.5DW model: The ATL-4.5DA adopts an electric unlocking design, which significantly reduces the intensity of operation and improves efficiency compared to the manual unlocking method of the ATL-4.5DW. It eliminates risks from manual unlocking and provides a safer, more automated, user-friendly operation.
