Overview
The Autoquip TorkLift T4 Quad Pantograph is the highest‑travel configuration in Autoquip’s premium TorkLift heavy duty scissor lift family. Four sets of vertically stacked scissors are pinned directly together, stabilized, and raised simultaneously by common hydraulic cylinders—delivering the maximum possible vertical travel in a compact footprint while maintaining the premium construction that defines the TorkLift line.
Like every TorkLift, the T4 delivers five times the life cycles of competitive heavy duty scissor lift tables. Originally developed by American Lifts and built in the USA for over 30 years, the T4 comes standard with captured rollers, two‑piece self‑aligning cylinders, and high‑impact spiral wound bearings. Capacities reach up to 6,000 lbs. The T4 is the right choice when your application requires extreme vertical reach and the premium durability that only the TorkLift construction can provide.
Features and Benefits
The quad pantograph design achieves the highest travel of any TorkLift configuration by stacking four complete scissor sets into a single structure. This consumes dramatically less floor space than a single‑ or double‑pantograph lift attempting to reach the same height through wider leg angles. All scissor rollers are captured within structural steel channels for excellent load stability at extreme heights. High‑impact, spiral wound bearings at every pivot point provide maintenance‑free resistance to abrasion, impact, and uneven loads across hundreds of pivot points.
Structural cross‑members at every pinned joint minimize leg deflection from twisting or spreading—a critical feature when four scissor sets are stacked and the structure must remain rigid across the full travel stroke. All hydraulic cylinders contain two‑piece, self‑aligning piston rods that transmit minimal side forces to cylinder hinges, significantly reducing wear. A low‑pressure hydraulic circuit extends hydraulic component life and reduces motor stress.
Chrome‑plated, 100,000 psi ultimate‑strength pins at every joint deliver premium load strength. A minimum 1/4‑inch‑thick steel‑reinforced platform minimizes deck deflection. Semi‑transparent polyurethane oil reservoir provides clear fluid monitoring. Double wire‑braided Parker hydraulic hoses resist wear, abrasion, and leaks. On‑board maintenance devices enable safe blocking during inspection. Autoquip backs the TorkLift T4 with an industry‑best 2‑year warranty on all parts.
Safety and Compliance
Hydraulic velocity fuses completely stop the lift in the unlikely event of uncontrolled descent. A minimum 3:1 structural factor of safety ensures reliable performance at the highest elevations. Each unit complies with ANSI MH29.1 for industrial scissor lifts, NFPA 70 National Electric Code, ASTM A36 structural steel standards, ANSI Z535 safety labeling requirements, AWS D.1 welding standards, and applicable portions of OSHA 29CFR1910 for general workplace safety.
Applications
The TorkLift T4 serves applications where extreme vertical travel is required and the lift must perform at premium cycle life levels with minimum downtime. Common uses include high‑cycle mezzanine access and multi‑landing material transfer in facilities that run continuous multi‑shift operations, personnel work platforms at elevated heights where structural rigidity and safety margins are paramount, high‑reach assembly and inspection stations where operators or materials must be raised to upper‑level positions repeatedly, and any production environment where a standard‑duty triple high or quad configuration cannot deliver the required durability and has experienced premature failure or excessive maintenance.
Selection Assistance
The TorkLift T4 is the right choice when your application demands the highest possible vertical travel with premium heavy duty construction and maximum cycle life. For moderate travel with premium construction, the single TorkLift (24–60 in.) or T2 Double Pantograph (48–96 in.) may be sufficient. For high travel with premium construction at lower capacity, the T3 Triple Pantograph is available. For standard‑duty high travel applications, the Series 35 Triple High offers a lower‑cost alternative. The T4 is reserved for applications where both extreme travel and extreme durability are non‑negotiable.
