The Quickchange® Moveable Barrier system is designed to create a positive traffic barrier between opposing lanes of traffic and between motorists and construction work areas. The Barrier Transfer Machine (BTM) laterally transfers the barrier wall, one lane or more, at speeds of up to 5 mph (8 km/h). This allows the contractor to quickly reconfigure the roadway to meet changing traffic demands and at the same time expedite construction.
By expanding the work zone during off-peak traffic periods, contractors can combine or eliminate stages and use larger, more efficient equipment to accelerate the construction process. This often results in eliminating one or more construction seasons. The system also reduces congestion by enabling more lanes to be open during peak hour traffic.
QMB is designed to accelerate construction, improve traffic flow and safeguard work crews and motorists by positively separating the work area and traffic.
