A deployable safety zone system includes at least a first arm mounted on a support member and being movable between stored and operating positions relative to the support member. The support member and first arm define a safety zone between then when the first arm is in the operating position. The safety system may include reflective mechanisms, light sources, and an alarming system. The alarming system may include a transmitter positioned on one part of the safety system, a receiver positioned on another part of the safety system and an alarm mechanism. A signal may be sent between the transmitter and receiver and if that signal is interrupted, a visual or audible alarm may be generated. Alternatively, the deployable safety zone system may comprise a sensor assembly disposed adjacent the support member The alarmed safety zone is defined between the support member and the sensor assembly.

An aerodynamic wrap for use with a tank trailer illustratively includes opposing first and second side assemblies. In an illustrative embodiment, each side assembly includes an upper panel pivotably supported by the tank trailer, and a lower panel pivotably supported by the upper panel. A lower connecting member illustratively couples the lower panels of the first and second side assemblies under the belly of the tank trailer.

A system for supplying dry air to a fuel tank to remove moisture and inhibit contamination includes a dry air supply assembly having an air compressor and an air dryer configured to remove moisture from air supplied by the air compressor to the air dryer, and includes a fluid pump mounted within the fuel tank above a fuel level, with the fluid pump receiving dried air from the air dryer. A suction line extends from the fluid pump and includes an open end disposed at a bottom of the fuel tank. The fluid pump is adapted to receive dried air from the air dryer as a motive force to draw liquid from the bottom of the tank into the opening and up the suction line to the fluid pump, and discharge liquid from the fluid pump above the fuel level within the fuel tank.

The present invention is directed to a mobile platform for the delivery of bulk explosives to a blast hole. One embodiment of the platform provides the ability to obtain weight information relating to the contents of a tank that is associated with the platform and that, in operation, contains either the bulk explosive or a constituent of the explosive. The platform comprises a vehicle with a frame, a tank, a load cell structure for connecting the frame and the tank and providing weight data relating to the contents of the tank, and a suspension system that prevents relative movement of the frame and the tank that could compromise the load cell structure. Another embodiment of the platform provides a tank for holding an explosive composition and a rotary shaft that supports a mixing blade that mixes the explosive composition within the tank. The platform further comprises bearing structure for supporting the rotary shaft that is located to deter any of the explosive composition from entering the bearing. A further embodiment of the platform comprises a conduit structure for discharging a bulk explosive into a blast hole that includes a substantially rigid tube with an outlet port for discharging a bulk explosive into the blast hole. The tube is adapted to rotate about a vertical axis such that the outlet port can be moved towards and away from the vehicle along an arc of less than 180. In one embodiment, the outlet port can be positioned substantially adjacent to an operator's station to allow an operator to readily view the loading of the explosive into the blast hole.

An aerodynamic device for a trailer is provided that includes an air fairing or skirt that smoothly transitions into a fender for the wheels of the trailer. The aerodynamic device may be a substantially unibody member that has a forward region, a transition region, and a rear region. The first region defines the aerodynamic skirt beneath the trailer and the second planar region defines the fender for wheels of the trailer such that the fairing smoothly transitions from the skirt beneath the trailer to the fender covering the wheels based the shape of the bend in the transition region.

A tank trailer includes a tank having an outer surface face and an inner surface and a central longitudinal vertical plane extending between the first end and the second end. The outer surface faces away from the central longitudinal vertical plane and the inner surface faces towards the central longitudinal vertical plane. The outer surface and the inner surface define an interior volume adapted to be filled with material. The tank trailer may further include a set of ground-engaging wheels supporting the tank trailer from below, a bar positioned proximate the outer surface of the tank and a light source provided on the bar. The tank may further include a frame member operatively engaged with the bar and a sheet material extending between the bar and the frame member. The frame member is movable between a first position and a second position.

Systems and methods are disclosed that may include providing a wellhead gas burner to burn wellhead gas produced from a wellhead to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may include a pressure regulator and an expansion chamber that permit the wellhead gas burner to continuously operate and accommodate wellhead gas pressure fluctuations. The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional propane/diesel gas burner system configured as a supplemental heat source. The wellhead gas burner may also be mounted to a mobile superheater truck.
