An American Crane lattice boom crawler crane drops a tamper weight for dynamic soil compaction at a construction site in Harrisburg, Pa.

For impact compaction, a heavy tamper weight is dropped from heights of up to 40 meters onto the ground to be compacted. This dynamic input of energy increases the density of the building ground.

The craters created through impact compaction are refilled with suitable material and further compacted, if necessary. Crawler cranes carry out the compaction process efficiently and automatically with free-fall winches and crane control.

In the foreground and background see all types of construction excavators, soil compactors, and Rokbak RA30 articulated haulers at work.
