RBP File No. 5770-001 A mobile carrier capable of carrying a number of gas cylinders comprises a generally horizontal first support surface with at least three wheel supports rigidly attached to it, each wheel support including a rotatably mounted wheel. The wheel supports are off-set laterally relative to the first support surface, the first support surface being below the top of at least one wheel support. An upright frame rigidly connected to the first support surface extends around three sides of the carrier. A second support surface is pivotally connected to an outside edge of the first support surface along a fourth open side of the carrier. The second support surface is pivotable between an upright position, where it may be secured to the frame, and a lowered position in which the second support surface is supported on another surface so that a gas cylinder may be moved between the mobile carrier and another surface by rolling the container about its axis between the first support surface and the other support surface along the second support surface.
