The integrated fracking system may include a variable frequency drive (VFD) coupled to the frame rails of the substructure assembly. The integrated fracking system may include a transformer coupled to the frame rails of the substructure assembly. The integrated fracking system may include a pump subsystem. The pump subsystem may include a first frac pump, a first motor operatively coupled to the first frac pump, a second frac pump, and a second motor operatively coupled to the second frac pump. The pump subsystem may be coupled to the frame rails of the substructure assembly.

Abstract: A frac system includes power generation equipment and a power storage device used to provide electric power to one or more pieces of frac equipment. The frac system includes a power controller used to control the source of the power to the frac equipment. The power controller may measure the charge status for the power storage device and the electrical power load being used by the frac equipment. The power controller may engage or disengage the power generation equipment based on the measured charge status and electrical power load, may control the source of the power provided to the frac equipment, and may control whether the power storage device is being charged.

Abstract: An integrated blender system includes a skid. The integrated blender system includes a blender assembly, including a blender tub including an outlet, a supply pipe coupled between a suction pump and the blender tub, and an outlet pipe coupled to the outlet of the blender tub. The integrated blender assembly includes a dry product additive system. The dry product additive system includes a skid, a hopper, a pickup funnel, a feeder system, a supply pump, and an eductor assembly. The feeder system may be configured to transport product from the hopper to the pickup funnel. The eductor assembly including a suction inlet, a motive inlet, and an outlet. The suction inlet may be coupled to the pickup funnel by a suction hose. The motive inlet may be coupled to the supply pump by a motive fluid hose. The outlet nozzle is positioned to eject fluid and product into the blender tub.

Abstract: An efficient, low-noise power generation system may comprise a power generation trailer including a cooling subsystem. The cooling subsystem may include a plurality of cooling fans and a polygonal structure having an open top. The polygonal structure may comprise a plurality of vertical radiator cores arranged so as to form a polygon in which the plurality of radiator cores define side walls. The cooling fans may be mounted within the polygonal structure. The cooling subsystem may include a cooling fan motor for each fan and a cooling fan controller that controls operation of each cooling fan motor in response to at least one measured parameter, which may be the temperature of a fluid flowing through one or more radiator cores. At least one fan is oriented so as to push air out of the top of the polygonal structure. The polygonal structure may have four sides.

Abstract: A railroad car moving vehicle comprises a chassis, the chassis including at least two ground wheels and at least two track wheels; a platform moveably mounted on the chassis; a platform lifting apparatus configured to move the platform between a raised position and a lowered position relative to the chassis, the platform lifting apparatus including a platform lifting cylinder operatively coupled between the chassis and the platform; and at least one locking leg, the locking leg positionable between an extended position and a stowed position, the locking leg preventing lowering of the platform when in the extended position.

Abstract: A syringe assembly for dispensing medicine from a cartridge having a diaphragm and a piston opposite the diaphragm. The assembly includes a barrel having a hollow interior, an open proximal end, a closed distal end, and an outlet. The assembly also includes a cartridge receiver slidably receivable in the hollow interior of the barrel. The receiver includes an interior space for receiving the cartridge, an access needle extending into the interior space for puncturing the diaphragm of the cartridge. The access needle directs fluid to the barrel outlet. The cartridge receiver includes a plunger rod movable into the interior space of the cartridge receiver for engaging the piston of the cartridge to selectively force medicine in the cartridge through the access needle.
