It pushes units that are within its unit capacity. (5 capacity can push one giant)
It does no damage to units alone.
Upgrading the push trap only increases the number of unit capacity it pushes.
The Push Trap, like any other trap in the Builder Base, does not need to be re-armed.
Strategy
Use the Push Trap to push away troops from critical buildings, like the Builder Hall.
Push units into other traps such as Spring Trap or Mega Mine or high-damaging buildings like the Crusher to do more damage to them.
When going against this trap, try to use one unit, such as a Raged Barbarian, to trigger this trap.
