Bottle Jacks
Vertical-action hydraulic bottle jacks from TradeQuip and Borum, rated 10t to 50t (and Borum 50,000 kg air-hydraulic variant). High-tonnage lifting in compact footprint - the trade standard for truck workshop, machinery service and heavy plant work where a trolley jack lacks the tonnage.
Tonnage ladder. 10t for light truck axle work. 12t to 20t for medium truck axle and unit lifting. 32t to 50t for heavy truck, prime mover, mining truck axles. Air-hydraulic variants (Borum 50,000 kg) for production workshop where manual pumping slows the cycle. Match tonnage to the heaviest load + 1.5x safety. Never undersize on safety margin.
Safety rule. Vehicle on a jack alone is unsafe. Always transfer the load to jack stands before working under. Jack stands take the static load; the jack is backup. Jack-stand-failure under load is a known workshop fatality cause.
