" They 're well suited for iber- to - the-home work. They 're built for residential and commercial areas. They 're lightweight and can be transported on a trailer pulled by a pick-up truck. Plus, they require minimal crews to operate." Compact directional drills, like the one Lemke Equipment uses, can of- fer as much as 9,800 lbs of thrust and pullback. That allows them to accom- plish a wide range of installation tasks. At Lemke Equipment , crews are using the drill to install a variety of conduit and duct for underground iber-optic cable installations. The user-friendly nature of the drill helps contribute to productivity. " These drills are very easy to op - erate. The computerized Smart Vice system simpliies the drilling process by automating the drill 's vice cycling operations," said Schneider. " The op - erator has single push button control of the function. That helps improve eficiency and speeds up drill times. The vice is also self-centering , reduc- ing wear and tear. The operator can return to manual control with the lip of a switch." High Production HDD Lemke Equipment does a consid- erable amount of work as a subcon- tractor for Central Cable Contractors, Waupun, Wisconsin, one of the lead- ing installers of iber-optic cable in the Midwest . Most of Lemke's work right now is in northern Iowa. In the larger towns, for larger projects, Lemke and his crews can be in the same area for up to six months at a time or more. Smaller towns can be completed in just a few weeks working 7 a.m. to 7 p.m., Monday through Thursday. " When we started working with them about ive years ago, they were doing work for Winnebago Coopera- tive Telephone Association (WCTA)," Lemke said. " If you're going to work for WCTA , you need a lot of experience doing lawless work and have good people skills. You also need to know how to, 'read the job' so to speak. You need to know what could be buried underground and know how to see it , without actually being able to see it ." While Central Cable does the main line work, Lemke and his crew work primarily in the neighborhoods, drill - ing under yards, driveways and park- ing lots. Lemke recently completed work on a WTCA project in North- wood, Iowa, which is located just south of the Minnesota-Iowa border. Lemke utilizes a four-person crew, two on the drill and two taking care of other parts of the project . For this sec- tion of the project , Lemke crews were installing small diameter micro -duct . Typical distances range between 50 to 100 ft , but his HDD operators have achieved longer distances of several hundred feet . " The most unique part of that in- stallation was the micro -duct . It has a diameter that 's less than the size of a dime," Lemke said. " We were only do - ing a pilot bore, no reaming , and then Lemke pays close attention to homeowners and makes sure to limit disruption on all installations. The Grundodrill 4X, with its special steel track and bonded rubber pads, helps minimize potential damage to concrete and turf.
