Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

Consolidating concrete where there is no power and no place to set a machine down means the power source has to travel on the operator, and the whole question becomes whether it can be carried for a shift. Multiquip's answer puts a four-stroke Honda engine on a harness built the way a hiking pack is built: contact points sit over the operator's center of gravity, the padding is chosen for breathability rather than bulk, and compression straps pull the load in against the back instead of letting it swing.

The engine is swivel mounted, so it follows the operator's body rather than fighting it when the shaft has to go somewhere awkward, and the throttle and the on/off switch sit on the shoulder straps within reach of a gloved hand. Upper-back load adjusters set the slack that decides whether the weight lands on the shoulders or the hips, a high-friction lumbar pad stops the pack creeping, and a low-oil shutdown sensor protects the engine when it is worked at an angle. This is built for the concrete crews placing in remote locations and on sites with no supply, not for the deck where an outlet is twenty feet away.

Common Applications

  • Concrete placement and consolidation where no electrical supply is available
  • Concrete placement in remote locations reached on foot
  • Consolidation work that moves continuously across a large placement
  • Concrete placement where the operator has to carry the power source rather than set it down

Selection Notes

  • Shafts and heads are not part of this order; the machine takes Multiquip's pencil and standard lines and the head size is specified separately against the pour
  • Choose this over the stationary G55H where the operator has to keep moving with the power source rather than work around a fixed unit
  • The engine is four-stroke, so there is no fuel mixing to manage on site
