Overview

Gorbel's Fixed and Adjustable Height Steel Gantry Cranes provide an economical way to lift materials anywhere in a facility. The wheels enable you to move the gantry around your facility. This is a more cost-effective solution ofr areas of infrequent lifts than a more expensive permanent structure.

Standard Features

— Non-marking, durable polyurethane casters or polyurethane wheels
— Bolted beam to upright connection
— Pre-engineered for use with powered hoists. A factor of 15% of the crane capacity is allowed for the hoist and trolley weight with an additional 25% of the capacity allowed for impact, thus giving maximum capacity use of the crane. Therefore, if it's rated for 1000#, it can safely lift 1000# without having to worry about hoist weight or impact loading.
— 6" diameter, polyurethane casters with steel core are standard.

Caster Options for 1-3 ton Gantry Cranes
