Abstract: The present disclosure relates to a hose quick connection device for a fracturing equipment, comprising: a hose holding and moving mechanism for holding a hose and moving the hose between an initial position and a target position, wherein at the target position, an end of the hose is aligned with a manifold interface; and a controller configured to: receive first orientation information indicating the orientation of the hose from the first sensing device and receive second orientation information indicating the orientation of the manifold interface from the second sensing device; generate a desired motion command for moving the hose to the target position, based on the first orientation information and the second orientation information; and control the hose holding and moving mechanism to execute the desired motion command to move the hose to the target position. The present disclosure further relates to a fracturing equipment comprising the hose quick connection device.

Abstract: A portable tank assembly that is movable between an operating position and a transport position that includes a tank assembly with a holding tank having an upper section that includes an upper wall and a lower section that includes a lower wall that tapers inwardly from the upper wall to form an orifice, a transport assembly that includes a base portion and an axle assembly. The base portion is affixed to the upper section of the holding tank, and the axle assembly includes wheels for transporting the holding tank along a surface, and a skid assembly that includes a skid plate configured to rest on a horizontal surface when the portable tank assembly is in the operating position and a plurality of legs connecting the skid plate to the holding tank.

Abstract: A mobile cart for carrying a plurality of fluid canisters. The cart includes a platform configured to support the fluid canisters. The cart also includes a base having a base body and a plurality of wheels movably connected to the base body so that the wheels can be selectively moved with respect to the base body between an extended position and a retracted position. In the extended position, the plurality of wheels extends from the base body so the cart can roll, on the plurality of wheels, over the support surface supporting the cart. In the retracted position, the plurality of wheels is retracted relative to the base body so that the cart cannot roll, on the plurality of wheels, over the support surface.

Abstract: A portable tank apparatus has a yoke pivotal on a transverse member between a service towing position and a raised position, and a pair of hingedly connected brace members at the rear of the apparatus and operable by an actuator to retract the wheels or lower the wheels to the ground.
