Flange Head Trapezoidal Screw Jack

Our flange head trapezoidal screw jack is a mechanical transmission device that converts rotational motion into linear motion through the meshing of trapezoidal threads and worm gears. The integrated flange head design enables easy and secure installation, allowing the screw jack to be firmly fixed on equipment or frames, which greatly enhances the stability of the whole system during operation. The trapezoidal screw, as the core transmission part, adopts a special tooth profile design, which not only ensures strong load-bearing capacity but also achieves reliable self-locking performance, eliminating the need for additional braking devices and effectively reducing potential safety hazards in high-altitude or heavy-load operations.

Crafted with strict quality control standards, this screw jack is suitable for both single-unit independent operation and multi-unit linkage, making it flexible to adapt to different working scenarios. Whether it is low-frequency intermittent lifting or long-term stable positioning, our flange head trapezoidal screw jack can maintain excellent performance, bringing more efficiency and safety to your production line.

Robust Flange Head Design: The one-piece flange head is precision-machined to ensure tight connection with the installation surface. It effectively disperses the load pressure, reduces vibration during operation, and improves the overall stability and service life of the screw jack. The standardized flange size is compatible with most industrial equipment, facilitating quick installation and replacement without additional modification.

High-Strength Trapezoidal Screw: The trapezoidal screw is made of high-strength alloy steel with carburizing and quenching treatment, reaching a hardness of HRC58-62 and a tensile strength of ≥980MPa. The optimized 29° tooth profile angle reduces friction loss to 60% of sliding friction while ensuring excellent axial load-bearing capacity, enabling stable operation under heavy loads of 5kN-100kN.

Reliable Self-Locking Performance: The trapezoidal thread structure has inherent self-locking characteristics, which can keep the load stable at any lifting height without external braking devices. The self-locking error rate is ≤0.02%, effectively preventing accidental falling of the load and ensuring the safety of operators and equipment.

Flexible Drive Options: It supports both manual operation and electric drive (AC/DC motor, hydraulic or pneumatic motor), meeting the needs of different operation frequencies and precision requirements. The manual operation adopts an ergonomic foldable handle, which reduces the gripping force requirement by 40% and relieves operator fatigue.

Strong Environmental Adaptability: The whole machine adopts a sealed structure with IP54 protection level, which can work stably in humid, dusty or harsh industrial environments. The working temperature range is -15℃ to 80℃, and a low-temperature derivative model (-30℃ to 80℃) is available for wind power, cold storage and other special scenarios, ensuring 98% transmission efficiency even at -25℃.

Our flange head trapezoidal screw jack is widely used in various industrial fields due to its excellent performance and flexible adaptability. It is especially suitable for scenarios that require stable lifting, precise positioning and reliable self-locking, including but not limited to:

Automotive Industry: Lifting and positioning of stamping parts, assembly of auto parts, adjustment of production line rollers, etc. It can meet the precision requirement of ±0.1mm for heavy-load handling, greatly improving production efficiency.

Wind Power Industry: Positioning of wind turbine blades, adjustment of tower components, etc. The low-temperature model can solve the jamming problem in salt spray and low-temperature environments, ensuring stable operation of equipment.

Steel Industry: Lifting and positioning of hot-rolled production line detection platforms, replacement of rollers, etc. It can complete the whole process of lifting, replacement and reset within 18 minutes, improving efficiency by 60% compared with traditional hydraulic jacks.

Semiconductor Industry: Precise positioning of 12-inch wafer production equipment, matching with encoders to form a closed-loop control system, achieving nanometer-level positioning accuracy.

Construction & Machinery: Lifting of construction equipment, adjustment of mechanical components, positioning of heavy-duty platforms, etc. It can be used as a single unit or in multi-unit linkage to meet the needs of large-scale lifting operations.
