TT Technologies recently introduced a large, in-stock inventory of pneumatic pipe ramming gear able to accommodate 4 through 120 in. (10 to 305 cm) casing installations. TT Technologies recently expanded its large diameter inventory to now cover direct connections to 108 and 120 in. (274 and 305 cm) steel pipe. This means that contractors and municipalities no longer need to wait for inventory or fabricate large step up adapters in order to accommodate their pipe ramming projects, according to the manufacturers.

During the ramming process the rammer is attached to the rear of the casing. The tool then drives the pipe through the ground with repeated percussive blows. Ramming tools, in general, are capable of installing 4- through 147-in. (10 to 373 cm) diameter pipe and steel casings. Ramming has proven effective for horizontal, vertical and angled applications. Ramming provides accurate installation of casing in a wide range of soil without surface slump, making it ideal for installations under railways and roads.
