FAN DRIVE:
The suction fan is direct driven by an 11-1/2" heavy duty over-center clutch through a 2-1/4" diameter straight output shaft. The fan hub is coated with anti-seize material and is positioned on the shaft by a 5/8" square by 4-1/4" long key and secured by a 1" - 14 by 2" long grade 5 bolt and split 'lock' washer. The 1" bolt clamps a 1/2" by 4" flat washer to the end of the output shaft and the washer is secured to the fan hub with four 3/8"-16 by 1" socket head cap screws and split 'lock' washers. The clutch housing has a double lip seal. The clutch shaft has a sealed pilot bearing and two 2-1/4" I.D. tapered roller bearings, each with a basic rating of 3,370 pounds radial and 2,330 pounds thrust. The clutch handle is extended to provide easy access by the operator, allowing engagement and disengagement of the fan while the engine is running.


SUCTION FAN:
The fan is 30" diameter, 8-1/4" wide at the tip and has six radial blades. The fan backing plate is 1/4" thick steel and the blades are 3/8" thick AR400 abrasion resisting alloy steel with 1/8" formed reinforcing welded to the back faces. The completed fan is stress relieved for two hours at 1100 degrees F. This treatment relieves stresses induced by welding and reduces the possibility of weld failure due to shock loads. The fan produces 24,200 C.F.M. of air movement through a 16" diameter by 10' long hose under normal working conditions.

FAN TO HOUSING EFFICIENCY:
A high efficiency fan and housing design combines a 30" diameter fan and low fan tip clearance. This provides substantial engine horsepower reserve for picking up dense leaf material under adverse conditions and prevents engine stall-out. It also prevents excessive material build-up in the fan housing and produces the most efficient ratio of intake to hopper air exhaust.

FAN HOUSING:
The fan housing is 37" high, 39" long, and 10-1/2" wide, made of 1/4" steel plate. For added resistance to abrasive debris, the housing includes a two-piece replaceable liner made of 1/4" thick steel. To prevent worn liner sections from being drawn into the rotating fan blades, the sections are secured by fourteen alloy steel flat head socket cap screws and stover lock nuts. The fan housing is rigidly attached to the engine frame. To prevent severe engine and P.T.O. damage should large foreign objects be sucked into the blower housing, the back of the blower housing incorporates a safety band clamped to the P.T.O. housing. This diverts shock loads to the engine frame and away from the P.T.O. housing and engine block. Fan removal is accomplished by removing eleven bolts on the adaptor flange at the front of the housing. In order to change the fan, it is not necessary to remove the entire blower housing.


FAN DISCHARGE:
Discharge is directly from the fan housing to the hopper via a 10 gauge all steel welded chute. The chute has a break-away connection with a 1/4" thick top plate sealed by a half inch thick closed-cell foam rubber gasket.







45 DEGREE HOSE ADAPTOR:
At the fan inlet, a 45 degree hose adapter for added hose movement and storage while keeping sealed air flow through out the suction process. Bolted design allows for easy interchangeability.




SUCTION HOSE:
The suction hose is 16" diameter, 10' long and includes a tube, carcass, reinforcing wire, cover, and cuff. The tube is abrasion-resistant NC/SBR and the inner surface has a wax blooming rubber liner that resists wear, reduces friction, and decreases build-up of leaf material. The carcass is multi-ply woven polyester fabric. The reinforcing wire is 0.177" diameter spring steel rolled at 1-1/2" pitch for easy flexing and long life.


The cover consists of black abrasive resistant neoprene over the entire outside of the hose, providing excellent wear and resistance to weather, oil, and ozone. Each end has straight heavy cuffs to allow bolting for strong installation. The hose weighs 7.5 pounds per foot to combine flexibility with heavy duty performance. A metal operator handle and arm assembly is provided at the intake. Pick-up is from the curb side with no interruption of normal traffic flow.


HYDRAULIC HOSE SUPPORT:
A 12 volt electric-hydraulic power unit provides up and down movement of the standard hose boom. This is done through a two inch cylinder that is activated with push button switches mounted in a hand held pendant which is mounted at the operator's station. The standard hose boom is designed with two flange bearings top and bottom, bolted solid with grease fittings included, less binding or ware on the boom is accomplished. The hose support hydraulic system is independent of the hopper dump circuit.




HOPPER AND HOPPER FRAME:
The hopper frame is 101" wide, 159" long and the cross members are made of 5" @ 9 pounds per foot channel supporting the width of the hopper. The main channels are made of 6" x 2" x 5/16" wall rectangular tubing and 34" wide by 155" long and are welded to the cross channels in such a way as to maintain a 6" overall height. The hopper and frame assembly form a unitized structure. The hopper dimensions are 101" wide, 186" long, and 80" high, creating a capacity of 30 cubic yards. This hopper capacity is achieved without an excessive front hopper extension.





The hopper is made from 12 gauge sheet steel all welded construction with five supporting ribs of 3" structural channel encircling the hopper for strength. The inside of the hopper is smooth for ease of dumping a fully packed load. The top of the hopper has four slide-in filter screens in four framed steel sections reinforced with 1-1/2" expanded metal. The replaceable aluminum mesh screen is bolted to the screen frames.

The hopper assembly is attached to the main frame by a 3/8" thick steel plate hinge assembly which is formed, bushed, and welded to the rear of the hopper frame. This hinge assembly attaches to the main frame with a 1-1/2" diameter by 39" long steel pin.


TOP HINGED DOOR:
The hopper has a one-piece top hinged rear door with spring-compensated counter-balance to aid in holding the door open for dumping. The door is made of 12 gauge sheet steel, rolled and formed to a semi-circular shape. The inside of the door is reinforced on all sides, creating a unitized box around the perimeter of the door. The top and bottom reinforcing angles are 7" by 4" by 12 gauge and the side reinforcing angles are 3" by 3" by 12 gauge. The door hinges are 1/4" steel and incorporate a connecting eye for the counter balance springs. The springs are 3" in diameter with a 24" free length, made from 0.4" diameter wire, and positioned 3" above the top of the hopper. Each spring generates a 460 pound load when extended 10" and 800 pounds when extended 18".


Each spring has a tension adjustment of 9" at the hopper end of the spring connection. Plates of 3/16" steel are welded to the bottom of the door, to create a positive, easy operated door lock.




HYDRAULIC SYSTEM:
The leaf collector has an independent hydraulic pump driven by the engine (not electric driven) to power the hopper dump cylinder. The hopper is self dumping, using a 6" diameter three-stage hydraulic cylinder with a capacity of 55,000 pounds, applied directly upward at the front of the hopper and allows for a 47 degree dump angle. This front mounted cylinder provides a positive mechanical advantage which permits smaller diameter cylinders at lower operating pressure, compared to high pressure, negative mechanical scissor type hoists. The hydraulic system includes an oil tank, valve for operating the hopper dump cylinder, hydraulic hoses, and all connections, and all connections operating at a maximum 2,000 psi.

TRAILER FRAME:
The leaf collector overall size is 101" wide, 365" long and 118" high. The main frame is 34" wide and 294" long, made of 6" x 2" x 5/16" wall rectangular tubing and 6" @ 10.5 pounds per foot steel channel. A 6" OD, 2-3/4" ID by 1-5/8" wire forged lunette eye is welded and gusseted to a 3/4" by 6" by 9" plate. The eye and plate are attached by four 1" diameter Grade 8 bolts to a 3/4" by 9" by 14" plate welded and gusseted to the 6"x4"x1/2" wall rectangular tube tongue. The plate incorporates eight 1-1/16" diameter holes on 4" centers to adjust for different towing vehicles.

A 12,000 lb. static, 10,000 lb. lift capacity, 4" square, drop leg, side crank jack is bolted to the trail frame tongue as a parking stand. The trailer has chains with safety hooks for towing.


TRI-AXLE SUSPENSION AND BRAKES:
The trailer has three 5" diameter tubular alloy steel axles rated at 12,000 pounds each, six slipper leaf spring assemblies rated at 6,000 pounds each, swivel equalizers between the axles, and oil bath hubs. Six 9.50 - 16.5 LT tires have a 66" track. Axles, springs, and tires are attached to a bogie sub-frame which is bolted to the trailer frame. The sub-frame is fabricated of rectangular 3/16" wall steel tube and is 129-1/2" long by 47" wide. There are five supporting cross channels of 6" @ 8.2 pounds per foot structural steel. The tire center line does not exceed the center line of the supporting springs by more than 12", thus distributing the weight of the hopper and contents.

The leaf collecting unit has electrically operated brakes on both axles, controlled from the towing vehicle with a plug connector between the trailer frame and the towing vehicle. The unit is equipped with an electronic brake control that requires no hydraulic connection to the towing unit and a break-away safety switch which will apply the brakes on all wheels in the event the towing vehicle and leaf collector become separated.



TOWING HITCH:
The unit comes with a heavy-duty Pintle tow hitch and safety chains.




SAFETY LIGHTING:
The unit is equipped with an orange safety beacon light that is activated when the engine is running.
