BML 12 Manual Spider Boom

, Placing Booms

The concrete placement boom model BML 12 is particularly suitable for concrete placing where direct distribution with truck-mounted concrete pumps or stationary concrete booms come up
against technical and economic limitations. The vertical swiveling distributor arm is a very helpful tool for distributing concrete on this model.

Areas of up to 430 mยฒ can easily be concreted with the BML 12 from a fixed place, avoiding the heavy work of delivery lines spread over the floors.
