Abstract: A towveyor cart for use in hoisting an object and in particular an object having first and second interconnected portions from a first level to a fully raised level. The towveyor cart has control means which include a main control valve for simultaneously raising the jacks to an intermediate position between the lowermost position and the fully raised position and separate jogging valves for controlling each of the jacks separately between the intermediate and raised positions. In this way, both jacks can be simultaneously rapidly raised to the intermediate position and then independently jogged by the jogging valves to the final fully raised position. Horizontal adjusting means are provided so that a combination of horizontal and vertical adjustment for each jack, independent of the other jack, is obtained. Additionally, the towveyor cart is provided with an improved air reservoir which is mounted beneath the work platform of the cart as opposed to the conventional location which is on the platform.
