Slide out pump stand for hydraulic fracturing equipment
First Claim
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
- a plurality of electric pumps fluidly connected to the formation, and powered by at least one electric motor, and configured to pump fluid at high pressure into a wellbore that intersects the formation, so that the fluid passes from the wellbore into the formation, and fractures the formation;
a variable frequency drive connected to the electric motor to control the speed of the motor that frequently performs electric motor diagnostics to prevent damage to the at least one electric motor;
a trailer on which the motor and pumps are mounted;
a platform assembly mounted to the trailer and from which at least a one of the pumps are accessible by operations personnel; and
support rails mounted to the platform assembly and that slidingly engage mount assemblies that are coupled to the trailer.

Abstract
A hydraulic fracturing system has a pump driven by an electrically powered motor. The pump pressurizes fluid which is piped into a wellbore to fracture a subterranean formation. The pump and motor are mounted on a trailer that is hitched to a tractor. A platform assembly is mounted onto the trailer, and which is selectively moveable between deployed and stowed configurations. The platform assembly includes a platform, a lateral rail assembly mounted to the platform, and gates on the forward and aft ends of the platform. The rail assembly and gates define a safety barrier to prevent operations personnel from falling off the platform. In the stowed configuration the platform assembly is anchored in place over wheels on the trailer. In the deployed configuration, the platform assembly provides work surface so that operations personnel can readily access the pump on the trailer.

9. A hydraulic fracturing system for fracturing a subterranean formation comprising:
-
a trailer; a pump on the trailer that selectively pressurizes fracturing fluid; an electrically powered motor that drives the pump; a variable frequency drive in electrical communication with the motor; a platform assembly coupled with the trailer and that is adjacent the pump so that when operations personnel are on the platform assembly, locations on the pump are accessible by the operations personnel, the platform assembly comprising; a platform with a deck and frame, support rails that coupled to the platform, and mounting assemblies attached to a frame of the trailer and which slidingly receive the support rails. - View Dependent Claims (10, 11, 12, 13, 14, 15)
