Tuesday Iron: GOMACO, Liebherr, and... sheep?
Our Woman in the Know, Jessica Klein, is back with another video with what you need to know today from Construction Equipment.
GOMACO's Polymer Paver at Conexpo
GOMACO will use Conexpo to introduce its Polymer Paver for the ultra-thin overlay market.The Polymer Paver can pave overlays on bridge decks and flat slabs in widths from 6 to 30 feet. The all-welded steel frame sections feature bolted connections, allowing easy width changes. The welded polymer paving pan sections are available in widths to match the frame sections. Vibration is provided by sectional rotary eccentrics supported by ball bearings. The vibration is coordinated to start and stop with the machine movement. A dual-drive 9-inch variable speed auger spreads the material ahead of the paving pan.
Get up there with Liebherr
Liebherr recently noted it’s expanding its telehandler lineup with the new T48-8s, which looks to hit a sweet spot for North American material handlers. This machine delivers a true 26.2-foot lift height with a 10,580-pound maximum lift capacity. That puts it in the heavy-duty industrial class without stepping into full monster telehandler territory. The big change sits in that boom. The T48-8s uses a boom that is about 22 inches longer than the Liebherr's T55-7s model. That single design shift unlocks more forward reach and an extra 3.3 feet of stacking height. Operators can now load containers, hoppers, and bulk trailers without burying the machine into piles.
A history of sheep(sfoot ) rollers
The sheepsfoot takes its name from the “technology” it emulated: the original compaction practice of driving a herd of sheep or other stock along the fill. Their hooves would penetrate and consolidate the material. The roller’s feet, arrayed around the drum, work in the same fashion as all those hooves. There have been several variations of the idea over the decades, including capped feet for less penetration; spikes for breaking rocky material; and flat-tipped wedges. Another variant is Hyster Co.’s “grid” roller, which instead of a spiked drum used a pair of drums constructed of 1½-inch steel bars on 5-inch centers, creating a 3½-inch grid for crushing and compaction.
