The Series 700J jib is a tie-rod based jib crane. Somewhat more economical than aluminum booms, these jibs utilize precision steel rail formed from 9-gauge steel for an easily-moved boom with 220 degree rotation. The boom features a running surface with less then 1% rolling resistance and is powder coated for a smooth, clean, corrosive-free surface. Air supply package is included. For custom jibs, low profile jibs, or portable pallet base mounts, consult us. Stud anchors or bolts are not included. For proper installation of a floor-supported jib crane system a minimum of a 6" thick reinforced concrete floor is required. Consult a registered structural engineer concerning your floor viability before installing a jib crane.
