Abstract
A barrier transfer machine includes a moveable chassis, an entry snout, an exit snout, a conveyor system, and a control system that aligns the entry snout with road barriers before the road barriers are picked up. The control system includes a barrier position sensor; an entry snout position sensor; and a processing system.
Claims20
A barrier transfer machine for picking up and repositioning road barriers, the barrier transfer machine comprising:
- a moveable chassis having a forward and a rearward end disposed along a generally longitudinal axis;
- an entry snout supported on the forward end of the chassis for picking up the road barriers from a road surface;
- an entry snout positioning mechanism for shifting the entry snout generally laterally with respect to the longitudinal axis of the chassis so as to move the entry snout side-to-side relative to the forward end of the chassis;
- an exit snout for placing the road barriers back onto the road surface;
- a conveyor system positioned between the entry snout and the exit snout for transporting the road barrier from the entry snout to the exit snout;
- and
- a control system for triggering the entry snout positioning mechanism to move the entry snout side-to-side relative to the forward end of the chassis for aligning the entry snout with the barriers before the barriers are picked up, the control system comprising:
- a barrier position sensor for sensing a position of one of the road barriers before the road barriers are picked up by the entry snout and generating corresponding barrier position data;
- an entry snout position sensor for sensing a position of the entry snout and generating corresponding entry snout position data;
- and
- a processing system for analyzing the entry snout position data and the barrier position data to determine if the entry snout is aligned with the barriers before the barriers are picked up by the entry snout.

- an entry snout position sensor for sensing a position of the entry snout and generating corresponding entry snout position data;
- and
- a processing system for analyzing the entry snout position data and the barrier position data to determine if the entry snout is aligned with the barriers before the barriers are picked up by the entry snout, for controlling the entry snout positioning mechanism to shift the entry snout side-to-side relative to the forward end of the chassis to correct any mis-alignment between the entry snout and the barriers before the barriers are picked up, and for generating an alert and transmitting the alert to a user interface if the entry snout is not aligned with the barriers.

A method of moving road barriers with a barrier transfer machine, the method comprising:
- sensing a position of a leading one of the road barriers before the road barriers are picked up by an entry snout of the barrier transfer machine;
- generating barrier position data corresponding to the position of the leading road barrier;
- sensing a position of the entry snout before the road barriers are picked up by the entry snout;
- generating entry snout position data corresponding to the position of the entry snout;
- comparing the entry snout position data to the barrier position data with a processing system to determine if the entry snout is aligned with the barriers before the barriers are picked up by the entry snout;
- and
- shifting the entry snout laterally relative to a forward end of a chassis of the barrier transfer machine, under control of the processing system, to correct any misalignment between the entry snout and the barriers before the barriers are picked up.

- and
- a processing system for analyzing the relative position data to determine if the entry snout is aligned with the barriers before the barriers are picked up by the entry snout.
