Space Restrictions – Line pumps are smaller than boom pumps and require a smaller footprint because they do not have large outriggers that extend. Trailer pumps can also be unhitched and maneuvered by equipment to get into tight places on job sites.
Overhead Restrictions – Line pumps do not need large amounts of overhead space to get set up, and, have low clearance heights so they can be brought inside buildings, through doorways, and under low bridges. Boom pumps cannot operate within 20-feet of power lines, so when power lines are present, line pumps are sometimes the only option.
Distance – Line pumps can pump concrete a greater distance than a boom pump, both horizontally and vertically. Stationary line pumps are used to pump concrete vertically to the upper levels in high rises, and long-distance horizontal pumping on bridge decks and other applications.
