摘要：
A jacking system includes a wheeled hydraulic power unit having an operating handle, and at least two extendable jack units which are identical.Each jack unit is adapted to rest upon the ground, and the power unit can be wheeled into (or out of) engagement with the jack unit. When engaged with a jack unit, the power unit is capable of extending (or raising) the jack unit; a ratchet on the jack unit then locks it in its extended position. A manual control on the power unit is coupled to the jack unit (when the two units are interengaged) for releasing the ratchet, so that the power unit can then lower the jack stand to its retracted position.
