Description

The trailer is deployed empty to well locations. 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
The paint system is shot-blast with epoxy primer and acrylic urethane top coat with the customer’s choice of color and other finish details. Optional organic zinc-rich primer is 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 the original manufacturer’s warranty. 

Features/Benefits

  • Hydraulic landing leg jacks: Two Ø 4-in. (101.6-mm) diameter hydraulic landing legs for raising and lowering the trailer for on-site deployment or for attachment to tractor. The legs are operated using a hydraulic pump mounted on the engine with a 10-gallon (38-L) hydraulic fluid reservoir. Each leg is independently controlled with a dual control valve.
  • Manifold: Fill and discharge by manually controlled butterfly valves; remote-control air-actuated valves available
  • Dust collector (optional): Wilco standard ASME cyclone dust collector or Wilco ASME dust collector with Donaldson ToritR filtration system available

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.
