Disclosed is a mobile instrument assembly comprising: a housing for accommodating one or more components of an instrument; one or more wheels for mobility of the instrument assembly; and a mounting assembly comprising: a support plate that is moveable with respect to the housing between retracted position and one or more extracted positions and that comprises, in its distal end, a pair of protrusions projecting from a surface of the support plate, wherein in the retracted position the support plate is substantially unexposed from the housing, and in each of the one or more extracted positions the support plate extends from the housing to respective extent such that perimeter of the housing and the pair of protrusions define a circular area of respective predefined diameter to allow for mounting a pressure vessel of corresponding size on the support plate between the perimeter of the housing and the pair of protrusions.

Present invention relates to gas cylinder lifting cart having a base frame, a long bar, a keeper bar where the cylinder can be held securely during transport by friction pads on holding brackets, with at least a caster wheel providing easy steering. The keeper bar provides open access to put on a gas cylinder, instead of the hassle, and inherent danger, of lifting a gas cylinder vertically up and down to put on the cart. The base frame has a slight bent angle to facilitate easy tilting towards a slant angle for transport.

A mobile storage apparatus for containers is provided. The apparatus provides a unique support assembly for holding a container. The assembly includes a latch mechanism that allows a clamp of cylinder to be moved from a closed position to an open position which creates clearance around a neck of cylinder to allow it to rotate without falling out of clamp. The other end of apparatus is structurally configured with a release plunger that can be retracted to allow rotation of cylinder along said other end. Rotatable wheels on a user side with a braking mechanism along a handle and a foot ledge allow improved maneuverability and stability.

The handcart has a pair of larger wheels at the back of the load-carrying platform and a rear axle located above the plane of at least the forward portion of the platform. Smaller caster wheels are mounted on the lower portions of the super structure of the cart. The caster wheels extend longitudinally forward from the forward corners of the platform. The lower portions of the super structure and the caster wheel are attached to the platform by gusset plates or arms. The gusset plates or arms may be welded to the platform and the lower portions at an acute angle relative to the upper surface of the platform.

A cart is disclosed for carrying a gas bottle. The cart includes a wheeled frame and a bottle support platform. The support platform is configured to pivot between a loading position in which a gas bottle may be loaded and/or unloaded from the bottle support platform and a cradle position in which the gas bottle and the bottle support platform are elevated. A bottle rest may support the bottle when the bottle support platform is in the cradle position. A bottle support spine may also, or alternatively, support the bottle during transportation and act as a lever for pivoting the bottle support platform between the loading position and the cradle position.

The present invention involves a device for holding and transporting a gas cylinder. The device, a hand truck, has an arm portion having a lip portion mounted thereon. The device also has at least one stabilizing peg mounted to the lip portion with two wheels mounted to the lip portion. The at least one stabilizing peg is sized and configured to engage the stabilizing ring of the gas cylinder placed on the lip portion. Optionally, a hook may be attached to the arm portion such that the hook may engage the gas cylinder. The arm portion may further comprise a handle portion pivotable between a raised position and a collapsed position. The handle portion is lockable in the raised position and the lowered position. The arm portion further comprises a cradle portion sized and configured to engage and stabilize the gas cylinder. The gas cylinder, having a stabilizing ring, may be tilted forward, and the hand truck may then be positioned to engage the cylinder. The gas cylinder may then be tilted back so that the stabilizing ring rests on the lip portion of the hand truck and is engaged by the at least one stabilizing peg. This allows for the tilting of the hand truck and cylinder backward so that the hand truck and cylinder may be wheeled freely.

The propane tank dolly comprises a base platform, a containment wall, a pair of wheels, and a handle. The propane tank dolly may be used to transfer a propane tank from a grill to a vehicle and may also be used to protect both the propane tank and the vehicle while the propane tank is transported to a tank exchange center in the vehicle. The propane tank is placed on the base platform within the containment wall and a lid may be placed onto the top of the containment wall. The handle may be extended from within left and right handle bases to move the propane tank dolly on the pair of wheel. The handle may be collapsed into the left and right handle bases to facilitate placing the propane tank dolly and propane tank into the vehicle.

A charging cart assembly for transporting a refrigerant tank. The charging cart assembly including a frame assembly having a handle at an upper end of the frame assembly and two wheels rotatably mounted to the frame assembly. A swivel plate assembly is mounted to the frame assembly. The swivel plate assembly includes a tank securing device arranged and designed to secure the refrigerant tank to the swivel plate assembly. The swivel plate assembly with the refrigerant tank secured thereto has a generally upright position in which the refrigerant tank is in a generally upright position and has a generally inverted position in which the refrigerant tank is in a generally inverted position.
