GENERAL

SPECIFICATIONS - COMBINATION SEWER CLEANER

BID #50-00144745

sewer and/or storm drain lines by the flushing action of high-pressure water. The high-pressure

sewer cleaner operates independent of the vacuum system.

The machine is capable of being operated by one man, with all operating controls for high-

pressure water pump, hose reel, and vacuum, located at the front of the machine for safety.

The machine shall have a total of 510 available horsepower. The auxiliary engine, water pump,

vacuum compressor, debris body and boom support assembly shall be mounted to a single

unitized welded sub-frame.

DEBRIS BODY

Debris storage body has a minimum usable liquid capacity of 9 cubic yards. The debris body

shall be round for maximum strength and constructed of 3/16-inch ASTM A242 Corten A steel

for enhanced corrosion resistance.

There shall be a 6” diameter liquid drain valve, “knife valve type” and screen weldment inside for

removing excess liquids. Drain will have 10 feet of 6 inch lay flat hose.

A rear door safety prop shall be provided. For ease of maintenance there shall be no hydraulic

components located inside the debris body or rear door.

Hydraulic operated, heavy duty wedge style door locks shall be installed. The door locks shall be

operated by two double acting hydraulic cylinders. The rear door shall also hydraulically open

and close (raise and lower) by means of two double acting hydraulic cylinders. The unlocking-

opening and the closing-locking operations shall be controlled by a single switch and sequence

valve.

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 tank.

These weldments shall be removable and require no cutting or welding.

A double acting power up/power down hydraulic scissors lift mechanism will be provided to

raise body to a minimum GO-degree angle. The scissors lift mechanism shall be designed to

support a minimum 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 is 56,000 lbs.

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.

The debris body has a five-year warranty. A copy of manufacturer's warranty statement shall

be enclosed with bid. If pro-rated so state:

An internal polyethylene float device with external indicator is supplied to show when body is

loaded to capacity.

AUTOMATIC VACUUM BREAKER

The automatic vacuum breaker assembly is located inside the body.

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 assembly shall

consist of a 12” inlet and two 8” ports that provide air flow to the vacuum system.

A full indication activates an automatic vacuum breaker shut down system that completely

shuts down 100 percent of the airflow to the vacuum system to prevent overfilling and

wastewater discharge into the atmosphere.

The vacuum breaker system is automatically activated (closed) when the parking brake system is

released to eliminate carryover during transit.

The system is controlled/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 system

can be used for safety in the event suction must be shut off in case of an emergency.

POSITIVE DISPLACEMENT BLOWER

A lobe type positive displacement blower shall be provided capable of 6000 CFM's and 18"

of Hg. with cyclone separator. Control of the blower regarding start, stop and the rate of

vacuum suction is performed from the front of the truck. A vacuum suction breaker

disconnect switch is provided to enable operator to pick up large debris with boom and place

debris on road surface. The vacuum system shall operate independent of the high-pressure

water system. The compressor is driven by the chassis engine via a closed loop hydrostatic

system using a variable piston pump and motor. This system shall include a heat exchanger for

extreme ambient conditions 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 bypass valve.

Hydrostatic loop filtration shall be accomplished by a 10 Beta micron return filter and a 10-

micron Absolute (no bypass) charge filter.

The blower is protected by (2) two 3" diameter vacuum relief valves. The system incorporates

an air/water separator and a sound silencer to separate material before it enters blower and to

ensure quite operation. A means of starting, stopping and varying the vacuum suction from

operator station at the front of the machine is provided. The blower is mounted on a frame

independent of the water tank. Unit must be capable of vacuuming under water without air

induction. A manometer/vacuum test may be required to demonstrate the system

performance. The positive displacement blower has a 12-month non-prorated warranty.

VACUUM PICK UP HOSE

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 for the

operator.

dual hydraulic cylinder and 230 degree of boom rotation powered hydraulically for non-

interrupted smooth movement. Boom to have a lift capacity of 500 lbs. at the front bumper.

The boom will be powered by an electric over hydraulic system: up/down by dual lift

cylinders. The right/left movements shall be hydraulic via worm gear rotation.

The boom shall hydraulically telescope a minimum of 10 ft. forward from the operator's station.

The height of the boom shall not change while the boom is being telescoped. A manual

override system shall be provided for right/left, and up/down functions in case of system

failure.
