Arctic Over-Sized Trailer


Arctic Over-sized Trailer


The Arctic Over-Sized Trailer is an Arctic tolerant container system used to handle cementing, fracturing or chemical blending.  The Arctic Container System is portable and skid mounted.  The Arctic Trailer is built for extremely cold environments mainly deployed in Alaska, Canada and Russia.  The Trailer is over-sized, over-height and over-weight, therefore the Arctic Over-Sized Trailer does not meet the Department of Transportation standards for operating in the contiguous 48 U.S. states.  Control, data collection, and recording consoles are located in the mid-section of the trailer; pumping systems are located in the aft or rear section;  power systems are mounted forward over the gooseneck; and self-contained lighting systems are mounted on the Arctic Over-sized Trailer exterior.

  • The Arctic Over-sized Trailer can be custom configured to include special devices to meet the requirements of any special circumstance either domestic or international.


Chemical Blending Trailer

Chemical Blending Trailer Exterior

Chemical Blending Trailer Exterior

Chemical Blending Trailer is primarily designed for cold weather service.  The Chemical Blending Trailer is unique in that it has large entry points that can accommodate both storage of chemical materials and blending of individual chemical materials.  In addition, this unit will transfer product to a single output area at the rear of the Chemical Blending Trailer.  The secondary or intermediate area is for control and monitoring methods such as running export pumps, and blending and managing ratios of chemicals.  The control area is also used for recording and implementation of computer outputs.  The Chemical Blending Trailer has a self-contained power system in the forward compartment that can handle both hydraulic and electrical components.

  • Can be configured to handle various sizes and styles of bulk tanks for chemical systems as well as pump and blending systems, including flow meters and density control
  • Chemical Blending Trailer can be built for warm weather environments as well as cold weather environments

Chemical Blending Trailer Interior

This is the interior of the Chemical Blending Trailer demonstrating the bulk tank storage areas, flow meters, density checking equipment and pump mounts for injectable chemical blending systems.

  • All interior surfaces in the Chemical Blending Trailer’s chemical area are treated with chemical resistant coating
  • Because interior surfaces might come into contact with raw chemical material, all interior surfaces are constructed of stainless steel

High/Low Control Cabin

High/Low Control Cabin - High Position

High/Low Control Cabin – High Position

High or Low Control Cabin (High position showing) gives you flexibility with regard to operating height.  Because of its hydraulic elevation system, the Control Cabin has the capability of being adjusted by a height of 24 inches.  This allows the Control Cabin to adapt to either an application where an eroded cabin height is required or it can adjust to maximum height when a stationary operation is necessary to accommodate a full height individual.

  • Completely self contained hydraulic system
  • Both lighting and hydraulics run on 12 volt power
  • Vent fans on lower half are easily maintained
  • Unit has four position lift points making it easy to install on walkway
  • High/Low Control Cabin is mainly built for harsh environments and cold climates
High/Low Control Cabin - Low Position

High/Low Control Cabin – Low Position

High or Low Control Cabin (Low position) showing eroded position so that overall profile of the unit is very low. No external air conditioning systems installed. This is for cold climates, and all the windows slide open for air flow for summertime operations. Mainly built for cold climates using a two piece door, remote control for the hydraulic systems to be lifted from the external points, and can be remotely controlled right from the ground if necessary.

  • Compact capability
  • Harsh/cold environments
  • Totally self contained
  • 12 volt connection
  • Complete access through the floor for control stands systems to be entered through

Large and Small Blending Cabins

Large Blending Cabin

Large Blending Cabin

The Large Blending Cabin is a large control cabin that manages a total blending system, involving several chemicals on a standard fracturing location.  The Large Blending Cabin has output type panels for environmental control of the cabin internally.  The side-mounted, one-ton capacity air conditioner aids in the evacuation of warm air when the doors are open, cooling the air down quickly once the doors are closed.  In the winter, the heat coils contained in the air conditioning system allows for rapid warming of the cabin.  The air conditioning/heating system is purposely side-mounted so that the overall height of the unit can remain at a minimum.

Custom features:

  • Custom windows and door openings allows for better access to control panels, plus allows for better viewing of the job site
Small Blending Cabin

Small Blending Cabin

The Small Blending Cabin makes use of sliding doors instead of swinging doors so as not to obstruct the outer walkways or to block interior unit controls. The Small Blending Cabin uses a standard rooftop-mounted air conditioning system to reduce the overall footprint of the unit. Windows are placed on both walls and the door to provide for the best visibility.

  • No evasive entry to outer walkways
  • Easily mounted: four lift points
  • Fully capable electronics and interface hydraulics

Nitrogen Control Cabin

Nitrogen Control Cabin

Nitrogen Control Cabin

The Liquid Nitrogen Control Cabin is particularly small in size due to the fact that it must allow more room for the operator to control the nitrogen tubular pumping systems without any potential contact with the equipment since liquid nitrogen maintains a temperature of minus 345 degrees Fahrenheit.

Custom features:

  • 12 volt flood lights
  • Custom ladder housing
  • Custom sized doors for best possible fit for the Nitrogen Control Cabin’s capabilities

The Fluid Analyzing Van illustrates the capabilities of General Truck Body to make custom alterations to a standard factory built van.  Customer requirements included a custom cabin top, cut-away of the van itself, and alterations to the body, which were all custom features installed by General Truck Body.  The interior of the Fluid Analyzing Van was also tailored to the customer’s needs. Alterations included access from the driver’s seat to the rear without opening doors, which allows easy access to storage at the rear of the vehicle.  In addition, the rear cabin’s interior is high enough for the operator to stand.  Plus, the proximity of the input/output materials to the rear of the Fluid Analyzing Van prevent contamination of the interior control areas.

Fluid Analyzing Van Interior

Fluid Analyzing Van Interior

The interior of this Fluid Analyzing Van exhibits the control area and demonstrates the capabilities of the pop-up cabin top to accommodate cabinetry, sinks, storage and microwave ovens.   The cabin’s interior is high enough for the operator to stand.  The rear doors on a standard factory van have been altered to half double doors with a single rear windshield, which allows for easier exit and entry, plus better viewing.  Fluids can be brought in from the rear without any exposure to the interior control area.  Samples can be taken and analyzed without having to exit the van.  Information can easily be transmitted via the on-board computers and electronics.

Containerized Control
