IMER's Gerris 800 is a self-propelled, tracked concrete placing boom built to distribute pumped concrete anywhere within a 26 ft reach and up to 37 ft of height, for crews placing concrete in tight or multi-level sites where running pipe by hand is not practical. Four self-leveling outriggers set it up on uneven terrain, expandable tracks add stability once positioned, and the three-section boom folds down small enough to pass through a standard doorway despite its reach.

Both configurations are the same machine above the power pack: one hydraulic three-section boom carrying a 4-inch heavy-duty pipe to a 4-inch flex hose at the working end, pairing directly with any concrete pump using 4-inch HD fittings, positioned by a wireless remote controller that comes as standard. What the buyer is choosing is what drives the hydraulics. The bi-energy build runs a Honda GX390 with electric start and carries a 120V auxiliary motor beside it, so the same unit works outdoors on gasoline and switches to shore power when it is taken inside. The lithium build has no combustion engine on board at all, which removes the question of ventilation entirely rather than managing it, and IMER rates its battery pack for a full work day. Where a site bars engine exhaust outright, the lithium is the configuration that qualifies; where it does not, the bi-energy build does the same placing work for less money.

Common Applications

  • Placing pumped concrete at height or in hard-to-reach positions on a jobsite
  • Working in enclosed spaces, on the auxiliary 120V motor or on lithium battery power

Selection Notes

  • Bi-energy runs on gasoline outdoors and on a 120V auxiliary motor indoors; lithium carries no gas engine at all
  • Pairs directly with any concrete pump using 4-inch HD fittings; the boom does not pump concrete on its own
