VBS Vertical Ball Screw scissors lifts offer dependable mechanical lifting solutions by supporting the scissors table and load from beneath and raising with a vertical ball screw actuator. Mechanical ball screws provide a high degree of precision and repeatability, and can be used in single or multiple screws to vary load capacity.

The ball screw actuator is mounted at the clevis end of the scissors lift, driven by a gear motor with instantaneous brake, and stabilized by the scissors leg assembly.  The actuator can be mounted below grade to provide 4-sided deck access, or above grade if 3-sided deck access is acceptable. Vertical Ball Screw scissors lifts provide the most cost-effective and low-profile of all the mechanical scissors lift solutions.  As with other mechanical lifts, predetermined work elevations can be programmed with the use of a transducer or encoder and a PLC motor controller.

Autoquip Spiralift Mechanical Scissors Lifts are designed and manufactured in America's heartland and are intended to satisfy customers that demand  the very best in reliable and programmable custom-built mechanical scissors lifts.  The Autoquip sales and design team excells in providing specialized, custom lifting solutions at the lowest possible prices and shortest lead times.

• Durability and Quality

• Joints, the most critical wear points in the lift, feature chrome-plated, 100,000 psi, ultimate-strength pins for premium load strength and long life.
• Minimum 1/4-inch-thick steel-reinforced platform minimizes deck deflection, maximizes load stability, and greatly extends the life of the platform deck.
• Solid steel legs and added stiffeners provide overall stability and straight, repeatable roller tracking as the lift raises and lowers.
• Vertical ball screws are very rigid and provide stable load support throughout the lift's travel.

Maintenance and Warranty

• Autoquip offers an industry-best 2 year warranty on all parts as a promise that you've purchased the industry's most reliable mechanical scissors lift.
• Maintenance-free bearings at pivot points require no lubrication.
• On-board maintenance devices enable maintenance crews to safely and effectively block open the lift during inspection and routine maintenance.
• Vertical ball screw actuator design is simple and easy to inspect and maintain.

Simplicity

• Vertical ball screw actuator is the least noisy of all mechanical actuators - providing a more tolerable and productive work environment.
• 1 to 1 ratio of actuator stroke to lift travel provides a more repeatable and accurate programmed elevation stop.
• Programmable mechanical drive allows the lift to be called/sent to multiple pre-determined levels.
• Stopped elevations are maintained indefinitely - a critical asset for alignment and precision applications.
• Drive motors are rated for variable frequency drive control signals.

Safety

• Over-travel and Under-travel limit switches are mounted in the lift base frame to prevent the mechanical actuator from self-destructing by overextending the actuator stroke.
• Minimum 3:1 structural factor of safety makes these lifts the most structurally sound lift in the industry.
• Compliance with recognized standards:

• ANSI MH29.1 - Safety Requirements for Industrial Scissors Lifts
• NFPA 70 - National Electric Code
• ASTM - A36 - Structural Steel Standard
• ANSI Z535 - Safety Labeling Requirements
• AWS D.1 - Welding Standards
• Applicable portions of OSHA 29CFR1910 - General workplace safety
