Embodiments are directed to improving transportation of tubular structures. A roller may have a housing having a vertical axis and one or more upper flanges. The one or more upper flanges may have an upper surface that is transverse and non-perpendicular to the vertical axis of the housing. Optionally, the upper surface may be curved. The roller may have one or more wheels that are rotatably coupled to the housing and that extend downward from the housing.

A vehicle moving device for moving a vehicle from a first location to a second location includes a frame having a first end and a second end. A driving wheel is coupled to the first end of the frame and configured to contact a vehicle wheel at a first wheel location. A holding arm is coupled to the second end of the frame opposite the driving wheel and configured to contact the vehicle wheel at a second wheel location. The holding arm holds the vehicle wheel in contact with the driving wheel as the driving wheel rotates the vehicle wheel.

A system, apparatus and method for on-demand fueling of vehicles with a mobile, motorized handcart including a cart body coupled with a fuel tank, a plurality of wheels operatively connected to the cart body, the wheels operable with a motorized traction system, a steering handle operatively connected to the cart body and including controls for controlling the motorized traction system, a coupling system for securely coupling the cart body to the fuel tank, a hose and a nozzle, a spill guard surrounding the nozzle, an electric pump for pumping fuel from the fuel tank to the customer vehicle via the hose and nozzle, and a display dock disposed on the cart body, the display dock configured to dock a computing device configured to display fueling parameters based on a customer fuel request received via a communications network.

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.

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.

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 vehicle jacking assembly includes a plurality of lifting units that is each coupled to a bottom side of a vehicle. Each of the lifting units is actuatable into an extended position to lift a respective tire upwardly from the support surface. A pump is coupled to the vehicle and each of the lifting units is fluidly coupled to the pump. The pump urges a hydraulic fluid into or out of the hydraulic piston of a respective one of the lifting units when the pump is actuated into a lifting condition or a lowering condition. A control is positioned within the vehicle to actuate the pump to urge the hydraulic fluid into a respective one of the lifting units based upon the driver's preference. In this way the respective tire can be lifted from the ground without requiring the driver to manually jack the vehicle.
