• Bulk Storage Trailer

    Our Wilco™ WST-1600 trailer-mounted stationary bulk storage bins incorporate four pressure vessels and are used for on-site storage and pneumatic-handling of bulk cement and other powdered bulk materials.

    The vessels can store up to 1,660-ft3 of bulk materials.

    Description

    The trailer is deployed to well locations empty. The trailer’s hydraulic landing legs are contracted and the four-tank trailer drops to the ground where it is supported by a specially-designed under-frame structure.

    Paint
    Paint system is shot blast with epoxy primer and acrylic urethane top coat with choice of color and other finish details. Optional, organic zinc rich primer available for units operated in marine environments or other harsh operating areas.

    Warranty
    Wilco WST-1600 bulk storage trailers are warrantied for 12 months from shipment date for repairs resulting from workmanship. Components for outside vendors including engines, compressors, axles and suspension are covered by original manufacturer’s warranty.

    Under-frame support structure

    The special under-frame support structure is designed to maintain structural integrity of the trailer in a variety of conditions. This frame is employed after the trailer is deployed to a field location and the landing legs are contracted.

    The air suspension air pressure is released, and the total weight of the trailer and its contents are supported by the under-frame structure. The design is such that if the trailer were deployed on uneven ground that the structure retains structural integrity.

     

    Hydraulic Landing Leg Jacks

    Two Ø 4-in. (101.6 mm) diameter hydraulic landing legs for raising and lowering trailer for on-site deployment or for attachment to tractor. Legs operated using hydraulic pump mounted on engine, with 10-gallon (38-L) hydraulic fluid reservoir. Each leg is independently controlled with a dual control valve.

     

    Manifold

    The manifolds used on our WST-1600 bulk storage trailers fill and discharge by manually controlled butterfly valves. Remote-control air-actuated valves are also available.

     

    Dust Collector (Optional)

    Wilco standard ASME cyclone dust collector or Wilco ASME dust collector with Donaldson ToritR filtration system are optionally available.
