760x470mm Single Motor Double Scissors Lift Frame

760 × 470 mm Single Motor Double Scissors Lift Frame

The 760 × 470 mm Single Motor Double Scissors Lift Frame is a compact and reliable lifting structure designed for applications requiring increased lifting height, improved stability, and precise vertical movement. It is widely used in electric work platforms, industrial lifting equipment, maintenance platforms, inspection systems, and customized automation machinery.

Featuring a double scissor lifting mechanism and single motor drive system, this lift frame provides better structural stability and greater lifting capability compared with single scissor designs while maintaining a compact installation footprint.

Structural Design

The lift frame consists of a double scissor arm structure, electric drive system, mounting brackets, pivot shafts, and platform support components.

The double scissor mechanism uses two connected layers of crossed lifting arms to achieve vertical movement. When the motor operates, the drive system controls the extension and retraction of the scissor arms, allowing the platform to move smoothly and maintain stability throughout the lifting process.

The 760 × 470 mm specification generally refers to the frame size or installation dimensions. The actual technical parameters, including rated load capacity, lifting height, stroke length, and lifting speed, depend on the specific engineering design and application requirements.

The double scissor structure improves load distribution, increases rigidity, and reduces platform deflection during lifting operations.

Single Motor Drive System

The single motor system provides lifting power through an electric transmission mechanism.

Depending on the application requirements, the motor may drive a screw mechanism, linear actuator, or other electromechanical lifting solution. The drive system should be selected according to working load, lifting frequency, operating speed, and duty cycle requirements.

A properly matched motor ensures smooth operation, reduces mechanical stress, and improves the service life of the lifting components.

The control system should provide stable acceleration and braking performance to minimize impact forces and ensure accurate platform positioning.

Double Scissor Mechanism Design

The double scissor structure allows greater lifting travel compared with single scissor mechanisms while maintaining good structural stability.

Because the lifting system contains multiple moving joints, precise machining and accurate alignment of scissor arms are essential for reliable operation.

The lifting arms are manufactured from high-strength steel materials to provide sufficient load-bearing capability. Pivot points are usually equipped with bearings, bushings, or wear-resistant components to reduce friction and improve durability.

Proper maintenance of pivot joints, fasteners, and drive components helps ensure smooth operation and extends the service life of the lifting frame.

Manufacturing Process

The production process includes steel material preparation, cutting, drilling, bending, welding, machining, surface treatment, assembly, and performance testing.

High-quality structural steel is selected to ensure strength and durability. During manufacturing, welding quality, dimensional accuracy, and assembly precision directly affect the safety and performance of the lift frame.

After assembly, manufacturers conduct inspections on structural alignment, motor operation, lifting movement, fastening conditions, and overall stability.

Quality Control Standards

Strict quality control procedures ensure reliable and safe operation.

Material inspection verifies that raw materials meet required mechanical strength standards.

Dimensional inspection ensures components meet design specifications and assembly requirements.

Welding inspection confirms structural integrity and connection reliability.

Functional testing evaluates lifting, lowering, and movement performance.

Load testing verifies safe operation under rated working conditions.

Surface treatment inspection ensures corrosion resistance and long-term durability.

Application and Selection Considerations

Before selecting a 760 × 470 mm single motor double scissor lift frame, users should evaluate required lifting height, load capacity, installation space, operating environment, and working frequency.

This type of lift frame is suitable for compact lifting platforms, industrial equipment positioning, ergonomic workstations, maintenance systems, and customized OEM applications.

Conclusion

The 760 × 470 mm Single Motor Double Scissors Lift Frame provides an efficient lifting solution for applications requiring higher lifting capability, improved stability, and compact structural design.

A reinforced double scissor structure, reliable single motor system, precision manufacturing process, and strict quality control ensure safe and efficient performance. Customized solutions can be developed according to specific load requirements, lifting range, and installation conditions.
