Sumner Manufacturing of Houston, TX, has launched what it calls a lightweight, portable and easy-to-assemble GH2T Gantry Crane, to provide mechanical contractors with portable lifting.
The GH2T Gantry Crane has a maximum lifting capacity of up to 2t (4,400lbs) and is available in four sizes scaled in feet (8, 10, 12 and 15ft) and 3 sizes scaled in meters (3, 4 and 5m).
The Sumner GH2T Gantry Crane is made of two A-frames and a cross beam.
Its A-frames lock in folded position using plunger pins and a removable ‘quick action’ locking pin. Each A-frame is equipped with 8-inch (200mm) lockable casters and weighs 113lbs (51kg) with casters.
A set screw on the trolley holds it in place during assembly. The trolley weighs approximately 15 lbs (6.8 kg). Cross beams come in seven sizes (8, 10, 12 and 15ft; 3, 4 and 5m) and feature two span adjustments on either end of 13in (33 cm) as well as nylon carrying handles.
The lifting handle is adjustable to allow height adjustments to be made in 6in (15 cm) increments. Minimum and maximum heights from ground to lifting eye are 83in (2.1m) and 113in (2.8 m) respectively. Maximum height to the top of the trolley is 113.5in (3.4 m). The maximum width of the A-frame when erected is 60.75in (1.54m) and its stored height is 100in (2.5 m).
The company explained that ease of transport is the prime driver of the GH2T Gantry Crane’s design. “Sumner's GH2T Gantry lift introduces a lightweight aluminum Gantry Crane into the marketplace that is much simpler to transport, assemble and adjust than comparable Gantry lifts,” said Brendan Conway, national sales manager.
“The entire assembly is light enough to be erected by a two-man crew, something that the market has been demanding. The advanced design allows a pivoting feature where the beam with trolley is inserted into the receiver of each A-Frames then raised, ready for final bolting of the beam.
“Height adjustments can be made on either side by one man using the adjustable mast lifting handle and removable quick-action mast locking pin,” Conway said.
He continued: “All beams come with convenient carrying handles on both ends. A-frame assemblies fold up and lock in folded position with plunger pins. The entire assembly is pinch-point free. Overall the advanced design of the GH2T Gantry makes the work of transporting, assembling and adjusting a gantry Crane a much simpler task.”
