One person can easily lift heavy equipment with these lightweight, yet extra durable, SPANCO Aluminum Gantry Cranes. Backed by a 5-year warranty, portable units are ideal for outdoor and wet lifting jobs and where constant assembly and knockdown is needed. Two quick pin assemblies break the crane down into three pieces (two A-frames and one top beam) for easy transport and storage. Infinitely adjustable I-beam lets you configure gantry to job. Non-scuff, chemical-resistant 6x2" polyurethane swivel casters lock at 90° intervals, making travel easier in a straight line and help prevent movement under load. Trolley and hand hoist not included. Made in USA.
