<br />i SPECIFICATIONS - COMBINATQN SEWER CLEANE
<br />WA VAC-�CON!
<br />V312HEW1500
<br />GENERAL
<br />The machine is capable of removing stones, grit, grease, sludge and other debris from sanitary sewer and/or storm drain lines by the flushing action of high-pressure water. The
<br />high-pressure sewer cieaner operates independent of the vacuum system.
<br />The machine includes an air conveying vacuum system to provide for the simultaneous removal of the debris flushed to the manhole by the high-pressure water system or for the
<br />removal of debris from sewers, sumps, catch basins, digesters, wet wells, bar screens, etc.
<br />The machine Is capable of being operated by one man, with al I operating controls for high-pressure water pump, hose reel, and vacuum, located at the front of the machine for
<br />safety,
<br />DEBRIS BODY
<br />Debris storage body has a mmimum usable liquid capacity of 12 cubic yards.
<br />The debris body is round for maximum strength and constructed of 3/16 inch ASTM A242 Corten A steel for enhanced corrosion resistance.
<br />The rear door shall be dished and flanged for maximum strength, full opening, hinged at the top with low profile and adjustable style hinges maintaining a 12' maximum overall
<br />height. There shall be 6" diameter liquid drain valve, knife and screen weldment inside for removing excess liquids. Drain will have 10 feet of 6 inch layflat hose.
<br />The rear door shall be supplied with a debris deflector shield located inside the debris tank that encompasses 75 percent of the rear door. The debris deflector shl0d shall
<br />deflect material from rear door and aid In draining off excess liquids. A rear door safety prop shall be provided,
<br />For ease of maintenance there shall be no hydraulic components located inside the debris body or rear door.
<br />The debris body has five (5) externalty mounted door locks that lock hydraulically. one manual T bolt is installed for operator safety. A hydraulic grabber shall be Installed and
<br />controlled by one hydraufic cyiincler externally mounted for ease of service. The hydraulic locks and grabber shall be operated by one (1) sequential control, In order to allow the
<br />operator to control the discharging of liquids from the debris tank by cracking open the door prior to the dumping procedure, the hydraulic grabber shall engage the door at the
<br />bottom of the door from 0" - 6". Beyond the 6" stroke, the grabber shall automatically disengage the door, allowing for the dumping of the debris tank.
<br />Dual steel weldments, with stainless steel screen 8" x 28" each providing up to 1200 square inches of added filtration for the vacuum system shall be provided inside the debris
<br />tank, These weldments shall be removable and require no cutting or welding.
<br />A cloubie acting power up/p,ower down hydraulic scissors lift mechanism will be provided to raise body to a minimum 50 degree angle. The scissors lift mechanism shail be
<br />designed to support a mWmum of 24 inches of the debris tank width to provide stability and when dumping on uneven ground. The lift capacity of hydraulic scissors lift cylinder
<br />is 56,000 lbs.
<br />Dump controls are located on curbside mid -ship of the unit, well forward of the dumping area for operator safety. A manual override system is provided in case of system failure.
<br />The debris body has a Amp#09" warranty, A copyp of manufacturer's warranty statement shall be enclosed with bid, If pro -rated so state� PJ 0 / i o yeo-r
<br />An internal polyethylene float device with external indicator is suppNed to show when body Is loaded to capacity.
<br />AUTOMATIC VACUUM BREAKER
<br />The automatic vacuum breaker assembly is located inside the body.
<br />The automatic vacuum breaker assembly shall be controlled by an electric over hydraulic circuit. The entire system shall be replaceable via a bolt on assembly. The assemb$y
<br />shall consist of a 12" inlet and two 8" ports that provide air flow to the vacuum system.
<br />A full indication activates an automatic vacuum breaker shut down system that completely shuts down 100 percent of theoirflow to the vacuu m system to prevent overfilling and
<br />wastewater discharge into the atmosphere,
<br />The vacuum breaker system is automatically activated (closed) when the parking brake system is released to eliminate carryover during transit.
<br />The system is controiled/activated, at the front hose reel control station. This enables the operator to pick up large debris with boom and place debris on the road surface. This
<br />system can be used for safety in the event suction must be shut off in case of an emergency.
<br />CENTRIFUGAL COMPRESSOR
<br />The centrifugal vacuum compressor shall be of 3-stage construction (i.e, 3-27" minimum diameter fans in tandem). The centrifugal compressor system shall operate
<br />independent of the high-pressure water system.
<br />The compressor is driven by the chassis engine via a closed loop hydrostatic system using a variab�ie piston pump and motor. This system shall include a heat exchanger for
<br />extreme ambient condidons and to maintain the pump suction oil temp at 160 deg, F. max. The heat exchanger shall be protected by a 30-micron filter and cold weather by pass
<br />valve. Hydrostatic loopfiltration shall be accomplished by a 10 Beta micron return filter and a 10-micron Absolute (no bypass) charge filter.
<br />To maximize long term durability by reducing the load on one side of the compressor, the compressor shaft shall extend through the compressor and shall be additional stabilized
<br />by using two high speed bearings, one at each side of the shaft, No exceptions will be allowed to this requirement.
<br />A means of starting, stopping and varying the vacuum suction from operator station air the front of the machine is provided. A centrifugal separator located In the inlet chamber
<br />to the fans with cleanout box is provided. The separator removes particles from the air stream, thus enabling unit to vacuum wet or dry material. The separator Is separate from
<br />the debris body, The centrifugal compressor (fan) system �s capable of producing 90% vacuum with no airflow. This feature allows material to be vacuumed under the water
<br />surface, I.e. lift stations, plugged manholes, etc. Unit must be capable of vacuuming under water 16.6' (200") without air induction. A manometer/vacuum test may be required
<br />to demonstrate the system performance,
<br />The centrifugal compressor shall have a, 5 year non -prorated warranty.
<br />VACUUM PICK UP H05E
<br />Shall be front loading, attached at the front of the machine in order to provide ease of positioning the machine over the manhole, as well as afford maximum safety lot the
<br />operator.
<br />The boom 8" will be mounted on a boom that wifl provide a minimum of 18'verticle lift utifizing dual hydrauflc cyiInder and 230 degree of boom rotation powered hydraulically
<br />for non -interrupted smooth movement. Boom to have a lift capadty of 500 lbs. at the front bumper.
<br />The boom will be powered by an electric over hydraulic system � up/down by dual lift cylinders. The right/left movements shaH be hydra0c via worm gear rotation.
<br />Control of the boom is by means of a joystick control at the operator's station, requiring no cables at operator's feet for boom operation.
<br />The boom shall hydraulically bsiescope a minimum of 10 ft. forward from the operators station, The height of the boom shall not change while the boom is being telescoped.
<br />• manual override system shall be provided for nght/left, and up/down functions in case of system failure.
<br />• boom coverage chart shall be provided staflng the square feet the boom covers.
<br />8 inch diameter pipe extensions with clamps will be provided and carried on the truck as follows:
