ROTOR SPEED

The standard rotor speed has been increased from 1450 RPM to 1700 RPM. By increasing the speed of the rotor to 1700 RPM, the tip speed of the knives climbs from 115 MPH to 132 MPH. The exception is any model with cupped knives. The cupped knife unit still turns at 1450 RPM. The cupped knife cannot be attached to the U-clamp without the D-ring. The D-ring cannot tolerate increased speed of rotation. The cotton option is 2000 RPM.

COMPUTER BALANCING

All Loftness rotors are computer balanced at full speed with knives on the rotor. After assembly, shredders are test run to insure proper balance and vibration-free operation.

ROTOR BARS

Four 5/8" x 2" bars are welded on edge to the 7 1/2" diameter 1/4" thick rotor tube and are welded to the end ring on both ends of the rotor. This bar is used to mount knives and stiffens the rotor giving it more strength. (Most of the competitive machines use a welded lug to mount knives to the rotor tube which does not add extra strength to the rotor. If lugs are long, they can be bent or ripped off completely when struck by a foreign object such as a rock. This can result in an out-of-balance rotor in a competitive machine.)

ROTOR LATERAL MOVEMENT LOCK

This exclusive Loftness feature positively keeps the rotor from moving side-to-side. This view of the center bearing shows how it’s done. The spacer between the rotor and the bearing keeps the rotor from moving toward the center. The washer is held tight to the other side of the bearing with the threaded bolt. The small roll pin keeps the washer from turning and the bolt from loosening. This sandwiching effect keeps the rotor from moving. It also eliminates the need for set-screws and the chance that they may loosen.

GEARBOX

A 280 HP gearbox is used on all models.

BEARINGS

The rotors are mounted on heavy-duty 2-3/16", American-made ball bearings. Bearing bolts are torqued to proper specifications. A special rotor-locking device is used to insure that the bearings do not come loose.

SPRING-LOADED PUSH-TYPE IDLER

The spring loaded belt idler provides more belt wrap around the pulley.

BANDED BELTS

The banded belt will eliminate belts flying off or twisting. A banded-belt will take more shock load than conventional belts. This type belt is more consistant in length than matched individual belts and have a longer life expectancy. 6-groove belts are standard on the 24-30 foot shredders and are optional on all other models which feature 4-groove belts as standard.

STEEL FLIPPER SHIELDS

One piece swinging steel flipper shields are used to protect operator from flying objects.

LINE SHAFT UNIVERSAL JOINTS

U-joints are used to couple the line shaft to the gearbox. (Most of the competition use a splined hub or chain coupler.)

LINE SHAFT BEARINGS

A bearing is used to support the line shaft midway between the gearbox and the end plate with the exception of the 12' model.
