This 2011 Keystone Oilfield Fabrication LLC unit is a dry bulk sand storage trailer — sometimes referred to as a proppant trailer or sand king — designed to store and deliver fracturing sand and other dry bulk proppants on oilfield wellsite locations. These trailers serve as mobile, self-contained storage and metering systems, allowing sand to be held in large volumes on site and discharged in a controlled flow directly to blending or pumping equipment during hydraulic fracturing operations.
The trailer offers a total storage capacity of 3,000 cubic feet divided across four individual proppant compartments, each separated to allow independent loading and management of different sand grades or to control discharge sequencing. The discharge system is an underbody conveyor with a corrugated sidewall belt measuring 24 inches in width, feeding material to a rear-mounted discharge chute. Power for the conveyor is provided by a John Deere 4045 HF diesel engine, which at the time of listing has accumulated 5,480 recorded hours of operation.
The trailer is equipped with a hydraulic power pack that drives several key systems, including hydraulic landing gear, hydraulic leveling, and full hydraulic controls for the conveyor and ancillary functions. A Webasto heater is fitted, providing cold-weather protection for the hydraulic system and related components — a practical consideration for harsh oilfield environments. The running gear includes spring suspension, aluminum wheels, 11R 22.5 tires, and air brakes. The unit's gross vehicle weight rating is 55,000 kg.
The seller indicates that multiple units of this configuration are available, and the trailer is located in New York, USA.
