ROLL OVER GANTRY WASH SYSTEMThe Gantry Wash, also known as a Roll-Over Wash or Automatic, utilizes a motorized frame that moves longitudinally along a track, forward and backward over a stationary wash target. These vehicle wash systems are supplied either as brush machines, high pressure "touchless" wash machines or a combination of the two for a Hybrid Vehicle Wash Solution. The most common application for the Gantry Wash System is where quality of wash is important. These vehicle wash machines provide consistent operation and in many cases can achieve a highly effective result that will exceed that found by hand washing with a brush and bucket. Typically a level or two more complex then a drive-through vehicle wash equipment layout, the roll-over gantry equipment currently available is well evolved with appropriate levels of engineering and technology applied throughout the scope of a modern large vehicle wash bay.

The general approach seen with a Gantry Wash Configuration involves a number of passes over the target wash equipment. The first pass may be a water rinse to lubricate surface grime, but more often this first pass will entail the application of a pre-soak chemical that activates a more aggressive loosening of any embedded surface elements. The pre-soak in many cases contains a high PH solution that can begin to lift dirt particles prior to a wash pass incorporating brush action, high pressure water application, or in the case of Hybrid Vehicle Wash Equipment, the dynamic employment of both. When Brand Image is a primary driver for wash system effectiveness, further gantry passes can be programmed to include subsequent application of low PH solutions, Polishing and/or Drying Agents, and in some Vehicle Wash Facilities, a hot wax is applied as well. 

The key advantages of a Rollover Gantry Vehicle Wash system include:

  • Consistent, High Performance Cleaning Systems that can be programmed to achieve solid wash effectiveness with disparate Fleet Equipment
  • Operational control of all wash elements: the wash target is stationary and the Gantry System is programmed to satisfy corporate wash goals
  • Engineered Equipment Solutions that are practical to operate, reasonable to manage, and offer strong returns on a Fleet Image Investment

Sprite Train Wash The Drive-Through Large Vehicle Wash System is comprised of stationary wash equipment and the target vehicles drive at slow speed through the wash station. As with the Gantry System, there are no limits on solutions that can be applied, or the manner in which the system attacks the grime on the system. Stationary Vehicle Wash Systems utilize Brushes or High Pressure Wash Components or the combination of both resulting in a Hybrid Stationary Wash System.

The key advantage of this "Tunnel Wash" approach is increasing the gross throughput of fleet vehicles that are cleaned by a discrete Wash System. In other words, the Stationary Wash System can wash more of a fleet in a certain amount of time. The longer the "Tunnel", the more vehicles can be processed simultaneously, resulting in higher wash output. Generally speaking, the Drive-Through system at its simplest level also has the advantage of being incrementally less expensive then a simple gantry system. However, based upon equipment additions designed to achieve higher levels of wash quality, a full scale Municipal Tunnel Wash or Metro Rail Wash System can quickly overtake cost aspects of the most highly featured Gantry Wash System. There is usually a happy medium where respectable wash quality is achieved while still maintaining target process time through the wash matrix.

As more of the human element is introduced into the equation, wash consistency and effectiveness is potentially more variable with a Drive-Through Large Vehicle Wash System. The driver is responsible for modulating vehicle speed as it passes through the stationary vehicle cleaning equipment. This possible speed variance will leave inconsistent results if the driver strays outside of the optimum design limits prescribed for each system. Bus Fleets and Truck Fleets are more prone to this particular characteristic as speed control typically is primarily a human function. Train and Metro Rail Wash Systems tend to have more consistent speed control based on definitive speed control equipment on-board these particular wash targets. In any event, the design decisions regarding how to best configure a Drive-Through Wash System should be developed with considerations to target wash vehicles, wash throughput desired, and quality of wash expected- all generally tailored to stay within particular budgetary requirements.

Drive-Through Large Vehicle Wash Systems can be best applied in environments where large number of fleet vehicles need expedited processing during the wash program. Equipment designs that are better suited for these Stationary Wash Equipment Installations include:
  • Metro Bus Maintenance and Wash Facilities
  • Metro Rail Maintenance and Wash Facilities
  • Rail Maintenance Facilities including capabilities for all tractors in addition to passenger specific rolling stock
  • Large OTR Fleet Maintenance Facilities or Distribution Centers
  • MODAL Transportation Facilities where high load counts necessitate corresponding high wash throughput needs

Optimum wash implementation is directly correlated to fleet make-up. Truck Washes developed for all straight vans or trailers will vary considerably from an Oil and Gas Equipment Wash that has to deal with varied equipment as well as typically higher concentrations of contaminants. Each Wash System should be chosen based upon fleet evaluation, wash result needs, and desired process speed. There is no limitation in terms of drive through or rollover- each of these solutions is available on both functional set-ups. Wash Dynamics will make the proper recommendations for appropriate equipment decisions based upon the particular demands of each corporate wash situation. To follow are basic considerations that can better direct the capital decision process to insure proper wash system selection. .

Brush Wash
The determination of brush wash solutions relies mainly on the Fleet makeup. For mainly OTR Fleets with a high degree of reefer or standard vans- brush wash systems are the most effective by far for a satisfactory wash result. The friction supplied by the brushes- through an appropriately judicious touch- is essential for lifting the stubborn elements of dirt and grime off painted and polished surfaces. This is also true for many municipal transit fleets that will have a large makeup of standard format equipment well suited for the friction wash solution. Though touchless wash solutions certainly have a well-deserved spot in the wash system line-up, friction wash systems are the preferred method to get a true shine on any equipment.

An important element of any vehicle wash with friction elements is proper lubrication of the wash elements to assist lifting and removing dirt particles embedded on the vehicle surface. Water and Chemical application points are strategically placed in the wash environment and will assure proper function of the brush media against the wash target. As the brush is responsible for the primary workload of removing surface contaminants, chemical use in a friction application tends to be notably less when compared to a touch free vehicle wash. This can be important in the long run as chemical costs are generally the largest operational expense in a large vehicle wash system.

The Large Vehicle Brush Wash Solution are preferred in:

  • Corporate Over the Road Fleets with "Standard" straight side configuration vans and trailers
  • Municipal Bus or Metro Rail Wash Systems with consistent equipment configurations
  • Situations When quality of finish is important for Fleet Image considerations

Touch-less or Touch-Free Vehicle Wash Solutions are the preferred equipment choice when varied equipment comes into play as the wash target. Obvious illustrations emerge in the Oil and Gas Equipment Industry where large size and profile variations are present across the equipment line-up. In addition, the environments experienced by this equipment also tends to generate notably large amounts of dirt, mud, ash, cement and other contaminants. Chemicals and High Pressure Water Applications combine to attack gross mud and muck accumulation in addition to a more fine wash expression for a clean final finish. The Touch-less Wash systems will be comprised of stations, otherwise known as "steps", that logically process the wash target for a positive end result.

Touch-Free describes the absence of any brush or other "friction" media; system viability necessitates a knowledged chemical application process combined with appropriate water pressure, or "impingement" on the target equipment surface. The high pressure water application has evolved from simple fixed arches to impressive combinations that can now include ultra high pressure spinners, blasters, undercarriage washes, de-mudders, wheel blasters, overhead contouring arms and diagonally stepped rinse arches that are combined in a custom configuration to provide the most logical layout for wash success. Wash Dynamics is expert in this critical design element and works very closely with each of the equipment providers to insure maximum wash effectiveness.

The other primary element of the Touch-Free Vehicle Wash System are Wash Chemical Solutions. High Ph Soaps, Low Ph Soaps, Neutral Rinses, Polishes, Drying Agents and Waxes can all be important components in the Touch-Less Solution. The lack of friction media requires judicious application of appropriate wash chemicals at the proper station, in the exact dilution, at the necessary pressure and appropriate rate of flow through the accurately sized delivery orifice. Unfortunately, too many operations lack the internal expertise to assess the source water make-up, and perform the solution evaluations necessary to adjust each of the many variables precisely. Wash Dynamics performs dynamic volumetrics to accurately access and define set-up configurations necessary to achieve high levels of wash chemical efficacy. 

Hybrid Combination Wash
Corporate focus on premium wash effectiveness necessitated the combination of Brush Wash Components and High-Pressure Touch-Free wash capabilites to derive the Hybrid Combination Wash. As implied, this wash system, in either Gantry or Drive-Through format, combines effective soft-touch capabilitiies with the blasting water elements generated with high pressure pump systems. With appropriate wash chemical application, this large vehicle wash system is the solution of choice for corporate fleets where a premium wash finish is expected. With an appropriate entry system, a Hybrid wash can be set to operate in Brush Mode only, Pressure Mode only, or both. This allows greater flexibility when meeting wash needs where variability of the fleet wash targets necessatate a responsive solution. The Hybrid combination wash is a logical choice when being considered for revenue generating wash faciliities- the flexibility will allow multiple wash programs that can be allocated to specific price parameters. Why outsource your wash business to Blue Beacon when you can incorporate a wash that will serve the corporate fleet in addition to drive by traffic?
