Under drum water tank
An on-board auxiliary tank system for supplying makeup water and chemical additives to a transit concrete mixing vehicle is disclosed. The system includes a water tank having a sloped, generally concave upper section, spaced sides and a bottom designed for deployment nested beneath a mixing drum of a transit concrete mixing vehicle and defining a water compartment and a pair of elongate support block members for supporting the water tank situated beneath the sides of the tank and adapted to be attached thereto by removable latch fasteners. The block members include elements suitable for fastening the blocks to a concrete mixing vehicle.
1. An on-board tank system for supplying makeup water and chemical additives to a transit concrete mixing vehicle comprising:
(a) a water tank having a sloped, generally concave upper section, spaced sides and a bottom designed for deployment nested beneath a mixing drum of a transit concrete mixing vehicle and defining a water compartment; and
(b) a tank mounting arrangement including a pair of separate elongate mounting block members disposed in spaced relation beneath said tank and removable threaded clamp fasteners attaching said tank to said separate block members, said block members including elements suitable for fastening said blocks to a concrete mixing vehicle, wherein the upper surfaces of said elongate mounting block members include a plurality of spaced raised knobs and wherein the bottom of said tank includes corresponding recesses for accommodating said knobs when said support blocks are assembled to said tank.
2. An apparatus as in claim 1 wherein said tank is provided with longitudinal recessed grooves extending along the sides thereof and wherein said clamp fasteners have shaft shapes and integral head members that attach to said tank by nesting in said grooves.
3. An apparatus as in claim 1 wherein said shaft shapes of said clamp fasteners include threaded portions and are secured through openings in said support blocks by threaded retainers.
4. An on-board tank system for supplying makeup water and chemical additives to a transit concrete mixing vehicle comprising:
(a) a water tank having a sloped, generally concave upper section, spaced sides and a bottom designed for deployment nested beneath a mixing drum of a transit concrete mixing vehicle and defining a water compartment, wherein said tank is provided with longitudinal recessed grooves extending along the sides thereof; and
(b) a tank mounting arrangement including a pair of separate elongate mounting block members disposed in spaced relation beneath said tank and removable threaded clamp fasteners attaching said tank to said separate block members, said block members including elements suitable for fastening said blocks to a concrete mixing vehicle,
wherein the upper surfaces of said elongate mounting block members include a plurality of spaced raised knobs and wherein the bottom of said tank includes corresponding recesses for accommodating said knobs when said support blocks are assembled to said tank,
wherein the removable threaded clamp fasteners have shaft shapes and integral head members that attach to said tank by nesting in said grooves and wherein said shaft shapes include threaded portions and are secured through openings in said support blocks by threaded retainers.
5. An apparatus as in claim 1 further comprising threaded fastening elements for attaching said elongated support blocks to a truck.
6. An apparatus as in claim 1 wherein said tank comprises a polymer material.
7. An apparatus as in claim 6 wherein said tank and said elongate support blocks are constructed using the same polymer material.
8. An apparatus as in claim 6 wherein said tank is molded from high density polyethylene.
9. The system of claim 1 , the tank including generally vertical slots for removably mounting and supporting the tank on the truck.
10. The system of claim 9 , wherein the generally vertical slots are shaped to accommodate the shaft shapes of the clamp fasteners.
11. The system of claim 1 , the water tank further comprising a liquid level sight gauge coupled to at least one of the spaced sides.
12. The system of claim 1 , the water tank further comprising a top discharge opening and a bottom discharge port.
13. The system of claim 4 , further comprising threaded fastening elements for attaching said elongated support blocks to a truck.
14. The system of claim 4 , wherein the tank comprises a polymer material.
15. The system of claim 14 , wherein the tank and the elongate mounting block members are constructed using the same polymer material.
16. The system of claim 14 , wherein the tank is molded from high density polyethylene.
17. The system of claim 4 , the tank including generally vertical slots for removably mounting and supporting the tank on the truck.
18. The system of claim 17 , wherein the generally vertical slots are shaped to accommodate the shaft shapes of the clamp fasteners.
19. The system of claim 4 , the water tank further comprising a liquid level sight gauge coupled to at least one of the spaced sides.
20. The system of claim 4 , the water tank further comprising a top discharge opening and a bottom discharge port.
