8-Ton (16,000 LBs) Hydraulic Bottle Jack Heavy Duty Car Lifter with Safety Valve

A trolley jack is no help when the vehicle sits high and the jacking point is a long way up. A bottle jack works the other way around: small footprint, tall reach, and a screw extension on the saddle to close the last few centimetres before the hydraulics do anything at all.

Ram protection built into the pump

The built-in bypass stops the ram travelling past its designed stroke, which matters more than it sounds. Over-travel is how a bottle jack loses its seal, dumps its oil and drops whatever it was holding. Here the pump simply stops making height once the ram reaches full extension, no matter how enthusiastically the handle is worked. Critical stress areas in the body are heat treated — those are the load paths that take the punishment when the saddle sits slightly off-centre. The steel saddle on top is shaped to bite on a chassis rail rather than skate off it, and a carry handle is built into this size.

Two capacity figures, and they do not match

The title carries both 8 tons and 16,000 lb. Those two numbers do not describe the same load, and the supplier's listing gives no basis for either — no test method, and no note on whether the rating covers lifting or holding. Both are published above exactly as supplied rather than quietly reconciled here. Work to the lower of the two, stay well inside it, and remember that a capacity figure describes what the jack will raise, never what is safe to lie underneath.

Key features

• Steel lifting saddle: engineered to hold the load securely on a chassis rail contact point.
• Extension screw: winds out to meet a high jacking point before any hydraulic stroke is used.
• Built-in bypass system: protects against ram over-travel at the top of the stroke.
• Heat-treated critical stress areas: the parts of the body carrying the load path are treated rather than left as raw casting.
• Carry handle built in: fitted to this size, which the smaller jack in the range does without.

Specifications

• Capacity, as listed in the title: 8 tons
• Capacity, second figure in the same title: 16,000 lb — the two do not agree with each other
• Height range: the supplier lists 228 – 458, printed in the source as centimetres; this figure is unverified
• Saddle: steel, with extension screw
• Over-travel protection: built-in bypass system
• Handle: carry handle built in
• Operation: hydraulic, hand pumped

Before you go underneath

• The jack raises the vehicle. It does not hold it. Chock the wheels, lift, then place rated axle stands under the chassis and lower the vehicle onto them before anyone goes under.
• Never rely on hydraulics alone for support. Seals fail, oil leaks and rams settle without warning.
• Use it on firm, level ground. A small base on soft ground will sink or tip.
• Lift only on the jacking points named in the vehicle's handbook.
• The two capacity figures in this listing disagree. Use the smaller one as your working limit.
• The supplier's text mentions an Australian and New Zealand standard, but supplies no certificate or test evidence. We have not repeated that claim, and this jack should not be treated as certified to any standard.

A jack this size suits trucks, 4WDs, caravans and heavily loaded trailers. Buy it alongside a pair of rated stands — the jack gets the weight up, the stands are the only thing that should keep it there.
