Trailer-mounted concrete pump uses steel or flexible concrete placing hoses to be manually attached to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed.
Most concrete pump jobs are either very large concrete placements or difficult to reach areas like a second floor or a basement with limited access. The ease and speed of using trailer concrete pumps to place the concrete will save you manpower and time, saving you money.
