Power-Assist Aluminum Oxide Lab Jack – 300 x 400mm 1-Stage Heavy-Duty Lift
The Power-Assist 1-Stage 300 x 400mm Aluminum Oxide Lab Jack is our largest standard rectangular lifting platform, engineered to provide an expansive and rock-solid foundation for oversized laboratory and industrial gear. This “Extra-Large” model utilizes a reinforced Single-Section (1-Stage) architecture to deliver superior stability and a smooth vertical range up to 315mm.
Key Features & Specifications
Extra-Large 300x400mm Surface: The rectangular 300 x 400mm platform provides ample space for wide-base equipment, multi-instrument setups, and high-capacity industrial heaters.
1-Stage High-Clearance Design: Unlike smaller 1-stage models, this heavy-duty version offers an extended lifting range from 90mm to 315mm, providing significant vertical clearance while maintaining a low center of gravity.
Power-Assist Bearing Technology: Equipped with precision pressure bearings and a bearing sleeve sliding mechanism. This allows for effortless, one-handed height adjustment even when supporting heavy 40kg loads.
Anodized Aluminum Construction: Crafted with 3mm thickened aluminum alloy plates and 10mm reinforced brackets. The anodized surface ensures a professional, chemical-resistant, and anti-corrosive finish.
Stable 40kg Load Support: Optimized for heavy-duty static loads, ensuring the platform remains perfectly level and wobble-free at any height within its range.
