Machinery manufacturer Husqvarna has made two new floor saws, the FS 6600 D and the FS 8400 D, available to the construction sector.
The equipment provides efficiency, precision and high productivity, while reducing strain on the operator, states the manufacturer.
A local case study was conducted and established, as an example, the effective use of the FS 8400 D floor saw.
“During the construction of King Shaka International Airport, cutting and drilling specialist Holmes Concrete Sawing & Drilling was approached by subcontracting company Ilembe Civils Joint Venture to perform some remedial work on the airport’s concrete aprons.
This required full-depth cutting through the apron slab. A Husqvarna FS 8400 D floor saw was acquired to complement the existing 65 hp saws, says Holmes Concrete Sawing & Drilling owner Andrew Holmes.
“[The Husqvarna saw] effortlessly cut 6 500 m [of concrete] 350 mm to 400 mm deep, 800 m at 400 mm to 450 mm deep and 800 m at 450 mm to 500 mm deep.
“All of this was achieved in just six weeks as a result of the FS 8400 D floor saw’s ability to cut the deep slabs in record time,” notes Holmes.
Husqvarna states that the FS 8400 D is the most powerful saw in the range and was designed to produce more horsepower at the blade spindle, increasing production in all cutting applications.
Patented power transmission with a right-angle gearbox lowers vibrations during operation, which increases the efficiency of the blade spindle. The control panel includes a temperature gauge, an ammeter, a tachometer and a blade clutch switch.
An IntelliSeal blade spindle has four sealed radial bearings for added strength and durability, allowing a minimum of 500 hours between maintenance intervals, with a 1 000-hour limited warranty.
An electrical tracking system also enables the operator to adjust tracking with a switch while cutting.
The FS 8400 D offers a maximum cutting depth of 620 mm.
Further, Husqvarna says the FS 6600 D floor saw’s power-to-size ratio makes it a versatile machine.
“It is a highly productive piece of machinery in all cutting applications, particularly when it has been fitted with a three-speed gearbox,” the manufacturer adds.
The floor saw features three gear speeds and two neutral positions and the gearbox’s shift lever positions are colour-coded to match the blade diameter and the blade- shaft revolutions per minute decal located on the control panel.
A gauge indicates the revolutions per minute of the bladeshaft or the engine. An electric tracking system also enables the operator to make tracking adjustments while cutting. The hydrostatic drive system with balanced dual-motor drive system means there are no belts, chains or gears to adjust.
The FS 6600 D saw offers a maximum cutting depth of 410 mm.
