DB225 Dustless Blasting rig and work trailer

  

DB225 Dustless Blasting rig and work trailer. No CDL required to haul. Problem was that I didn't have a building or a garage big enough to keep the trailer in...

The trailer is designed to be parked along the right side of the road and either allow blasting right out of the back of the trailer (within reach of the 50ft blast hose) or permit the portable blaster (DB500 too big to move), to be ramped down and moved up to 100ft away. The hose reels will then supply the air and water needed at the blasting site. When in the trailer the 7gpm electric pump supplies water to the blaster for filling and the blaster has a direct air connection to the compressor (with an isolation ball valve on both the blaster inlet and compressor outlet). The 75ft coxreel cord can supply 20 amps to the job site, it has a rubber water resistant sealed plug. The electric jack has a leveling bubble to determine when trailer is level. The trailer has both AC and DC systems. The DC systems include: one main system powered from the battery of the compressor and another small system that is integral to the trailer and powered from the 7 way towing connection cable. The integral system provides power to all the turn signals, running lights, and also one "loading" spotlight that illuminates the area where a pallet of media would be loaded (inside the trailer - currently in the picture the pallet jack and buckets reside in that space). The main DC system is powered from the compressor battery and operates 3 more of the DC spotlights operated by a BLACK switch next to the main entry door (so you can turn lights on in the trailer when it is not connected to anything and the generator is off). The main DC system also provides power for the DC fuel cutoff valve that feeds the generator. This system powers the DC control panel which includes 2 switches (one for the generator fuel and one to power the LED voltmeter that displays DC bus voltage) as well as a USB charging port. The main DC system also provides power for the electric tongue jack which can be locally switch operated (with a light too) or remotely operated with a wireless controller FOB. The AC system may be powered from either the generator or the 65ft cord reel the reel has a plug on the end of it for plugging into an outlet of a house, building, etc. The power then travels into the 30 Amp 3 pole double throw switch which can be OFF, Selected to Generator power, or selected to cord reel power. That power is then sent to the breaker box and then distributed to the trailer loads. Loads include: the Coxreel 75ft cord reel, 3 overhead mounted shop lights (middle and back light are WHITE switch controlled, front one over workbench is always on when power is present and breaker is shut), 3 WHITE GFCI 20 amp outlets (front, middle, rear), and one 240V/50 amp welder receptacle (generator only capable of 30 amps) to run 240V loads (a welder was intended, most 240v/30 amp machine plugs fit the 50 amp receptacle). The 50 amp receptacle is powered directly from the generator - so when the generator is running and the double throw power selector switch is selected to cord reel power, you can power the trailer from cord reel power but power your welder as the only load on the generator. There are also 4 receptacles in the generator control box. The generator control box has AC voltage indication, the start/run/stop button, and 4 receptacles - this box is mounted inside the trailer. The choke/throttle control and the fuel supply control have also been moved inside the trailer - so you can start and stop the generator from inside the trailer.

The generator also has an "idle down" control so that if it senses no load it will cut down to idle to save fuel and be quiet. Once a load is sensed it will speed back up to supply power at 120V. The generator is mounted on composite decking on the tongue. It is internally neutral bonded to ground (to the frame) so the frame of the generator is bonded to the frame of the trailer as well. Supplied (I'm changing out the one in the pictures) will be a frame grounding spike that can be pushed into the ground to ground the trailer frame to maximize electrical safety.

Compressor - The compressor is mounted over the axels perpendicular to the length of the trailer for preferential weight distribution. The exhaust has been modified to allow piping to pass through the deck and out behind the rear driver's side wheel. The passenger side opening also has the control panel for the air compressor and the valves to control where the air is supplied to. Drain hoses allow the compressor to be drained of engine and compressor oil to a catch placed beneath the trailer (The drain pans do not have plugs, but valves attached to hose drains - so fluid exchanges are easy). The control panel has been removed and mounted to the passenger side for easy control. The compressor is mounted on an aluminum pallet that allows the compressor to be moved by the pallet jack if needed and also allows the "hood" of the compressor to fully lift up inside the trailer for access to the machine's components. The compressor is strapped down on both ends by heavy duty strapping to heavy duty 6000 lb metal backed D-Rings installed in the deck. Reels - There are 4 reels on board, all spring return. One is the 65ft cord reel with a plug on the end that is only used to provide power to the trailer from a standard outlet. The second electrical reel is a 75ft commercial grade Coxreel with a sealed receptacle on the end used to deliver power to the job site. The other 2 reels are the same exact reel, commercial grade Coxreels of 100ft of 3/4 300psi hose providing compressed air and water to a remote job site. The air reel can be isolated (along with the pneumatic diaphagm pump) by a valve at the compressor outlet. A second valve isolates the air supply to the blaster. The water hose has a high capacity firefighter style hose nozzle (for wash downs or high volume filling of buckets for blaster loading).

The Air hose end [will] have a 3/4 inch ball valve followed by a 1/4 inch quick connect (for use of pneumatic tools) and a standard chicago/universal fitting (for the blaster). The reel stand has through bolts securing it to the deck. Pumps - There are 2 pumps on board.

The 24gpm pneumatic diaphragm pump provides the water hose reel and is driven by the compressor. When compressed air is supplied to the air hose reel, the pump will also receive operating air. It will deliver water to the water hose reel until the pressure is equal to the supplied air pressure and then it will stop pumping until there is a water demand. The 7gmp DC electric pump supplies water only to the hose adjacent to the blaster for filling/washing etc. It is powered by the 12V battery of the compressor. The pump senses and maintains outlet pressure - so it will shut itself off if there is no water demand from the hose so that it will not draw down the battery if the compressor is not running (even if you leave it on). Power to the pump is controlled by a BLACK wall switch mounted next to the blaster. Water Tank - A 275 gallon water tank provides enough water for a pallet of media (40 bags) plus additional wash down water (by the water hose or running the blaster with no media). Though very simple, the design is perfect for the task. It has been marked out in 5 gallon increments to assist in chemical mixing calculations. It has it's own cutoff valve at its outlet. The tank can also be moved by the pallet jack when full, or by hand if empty. It is secured to the deck with two heavy duty straps and 4 6000lb D-Rings. It has a 6 inch cap in the top for filling. The DB225 is the sweet spot between the too small DB150 and the unmovable DB500. The blaster is ratcheted down in place on the rear left side allowing for direct reloading from the pallet of media placed rear right. It has a dedicated air connection with isolation valves on both ends. It receives water from the 7gpm DC pump for filling (this allows water use, wash down, filling, without the compressor running). It can be freed and rolled down the aluminum folding ramp to a remote job site. The ramp can also be used with the hand truck and/or a cart/wagon. It is oriented for optimal use and loading, as well as blast hose stowage (on the pull handle, not shown that way in picture). It is strapped down with "comfort grip" straps for safety and ease of use. INCLUDED SUPPLIES (these will vary). 7 gallons of Hold Tight Flash Rust Inhibitor. 2 Bags of 40/70 crush bottle glass media. Gray seal caulk, exhaust pipe seal compound. A lot more stuff that I can't think if right now like spare parts and all kinds of things. Obviously contact me to set up an appointment to come see/demo the unit, it is located near Chattanooga, TN. The item "DB225 Dustless Blasting rig and work trailer" is in sale since Sunday, June 3, 2018.
