The used material handling equipment market has been very slow. This is for several reasons.
Slow “new product” deliveries make the availability of used product attractive. But so attractive it is seldom available.
And when it does it can be hard to sell because of current labor costs. Anything used takes more time to install than new. In addition it needs to be dismantled, loaded to trucks, moved, redelivered and installed again. Add these costs and new often just makes more sense.
