A laboratory lift mechanism includes a platen rotatably engaged with a base in a laboratory cabinet. The platen can support a heavy piece of laboratory equipment. Lift bags are engaged with the base and can be inflated to raise the base with the laboratory equipment.

An adapter assembly for lifting a vehicle includes an adapter defining a first pin aperture, a second pin aperture, and an adapter aperture, a first pin, a second pin, and a cross member removably received by the adapter aperture. The first pin is configured to be removably received by the first pin aperture and a first aperture defined by a frame of the vehicle to selectively couple the adapter to the frame. The second pin is configured to be removably received by the second pin aperture and a second aperture defined by the frame of the vehicle to selectively couple the adapter to the frame.

A jack with a double high-pressure structure is provided, including a base, a pump body installed on the base, an oil cylinder, an oil drain valve, and a safety valve. The base is provided with a low-pressure check valve and a high-pressure check valve A. It is characterized in that a high-pressure check valve B is also installed on the base. The present invention can improve the safety performance during use and prolong the service life.

A hydraulic power unit for a floor jack that includes an internally-adjustable relief valve that is inaccessible to an operator without removing the power unit from the jack assembly and disassembling the power unit. By placing the relief valve inside of the hydraulic assembly, hidden from operators, the relief valve is less likely to be accidently adjusted when using or servicing the jack.

A vehicle system includes a chassis and a lift assembly. The chassis includes a frame defining a first aperture and a second aperture. The lift assembly includes an adapter assembly and a lift device. The adapter assembly includes (a) an adapter defining a first pin aperture, a second pin aperture, and an adapter aperture, (b) a first pin extending through the first aperture and the first pin aperture and a second pin extending through the second aperture and the second pin aperture to selectively couple the adapter to the frame, and (c) a cross member configured to be received by the adapter aperture. The lift device includes a pair of receivers configured to engage the cross member of the adapter assembly to support the cross member. The first pin aperture and the adapter aperture each extend laterally when the adapter is coupled to the frame.
