OZ Lifting has launched a third lever hoist range, Dyno-Hoist, a dynamometer-equipped product from 0.75 to 9 tons capacity.
The Winona, Minn.-based manufacturer is the first to bring a lever hoist that includes a dynamometer to the North American market. It is available in 0.75, 1.5, 3, 6, and 9 tons capacity, matching the ranges of the company’s industrial and overload protected lever hoist offerings.
Dyno-Hoist, named by Richard Miller, sales manager, gives users a real-time reading of the load (in kilograms or pounds) they are applying to the hoist, whether it be a lifting or pulling application. An overload alert is triggered at 126%; the American Society of Mechanical Engineers requires that when a hoist is repaired or recertified, it gets tested at 125% of the rated capacity. OZ Lifting wanted to be sure that the hoist could be tested to that capacity without timing out. Against best practice advice, users could operate it beyond that point, but they would have no knowledge of the load being applied.
The net weight of the units (head only), is 16.5, 27.94, 45.1, 66, and 96.80 lbs. in order of capacity, while the effort to lift the safe working load (SWL) in each instance is 31.4, 49.5, 72, 76.5, and 81 lbs. The first three models in the range have one fall of chain and the 6 and 9 tons versions, two and three falls respectively. Other features include all-steel construction; steel handle with rubber grip; zinc-plated load chain; forged alloy steel hooks; and fully-enclosed gearing. Dyno-Hoist meets or exceeds CE, ASME B30.21, and AS 1418.2 standards. Standard AA batteries offer a run time of 150 hours, but the product can be plugged into a 115/1/60 outlet. Each hoist is load tested and arrives with a test certificate, one-year warranty, and a free set of latches.
