Akkerman Celebrates 40 Years Strong

October 2013, Vol. 68 No. 10

Akkerman’s Guided Boring Machine (GBM) systems or pilot tube microtunneling products are able to achieve longer drive distances due to enhanced optics in the guidance system and by maximizing the hydraulic capabilities of power packs. And the company’s manned pipe jacking equipment is designed as a complete, all-in-one system.

Akkerman equipment installs a range of pipe materials in numerous lengths although they specialize in equipment for minimal diameter shafts. The systems are used to install reinforced concrete pipe, clay pipe, polymer concrete, centrifugally cast fiberglass reinforced polymer mortar, and steel casing, as well as liner plate, ring-beam and lagging and concrete segments.

Rolled out just this year, the newest guided boring machine – the 4815a GBM – features a maximum jacking thrust of 265 tons with a fast advance speed rated at 100 tons. The rotational torque operates in two ranges, 0-10,500 foot-pounds and 0-26,000 foot-pounds maximum torque. Each torque range offers a two-speed option, 35 rpm and 50 rpm in the low torque setting; and 23 and 35 rpm in the high torque setting. The 4815A is designed to work out of 15-feet minimum round or square shaft. The frame’s 7.5-inch cylinders have a 30-inch stroke and reposition on center every 24 inches to allow for up to 96-inch pipe segments. The 4815A performs with all existing GBM tooling currently used on 240, 308 and 4812 jacking frames.

Maynard says that immediate growth plans include continued efforts to leverage Akkerman’s core assets – experience and varied product lines.

“We will continue to evaluate our equipment lines and offer enhancements and new developments as necessitated by the industry,” he says. “And keeping up with changes in the trenchless industry, specifically the slowdown in domestic municipal spending on infrastructure projects, has necessitated we make a more concerted effort to grow our foreign sales. Thus far, Akkerman machines have completed jobs in 17 countries.”
