Niko A-frame gantries are a 3-piece construction, 2 A style legs and a cross beam which connects the 2 legs together. Niko A-frames can be supplied in a fixed or mobile option, fixed to remain as permanent fixture for one operation. Mobile A-frames can be used in multiple locations. Our mobile A-frame gantries are designed not to be moved under load. The A-frame should be pushed into position, secure the wheels then lift and traverse the load along the beam.
