OZ Lifting has expanded its industrial lever hoist range with 6- and 9-ton capacity versions.

Previously, the Winona, Minnesota-based manufacturer offered 0.25- to 3-ton capacity models, but the relaunched range will include 0.25-, 0.75, 1.5-, 3-, 6-, and 9-ton capacity versions. This closely matches the company’s premium (overload protected) and dynamometer-equipped (Dyno-Hoist) lever hoist lines.

While the premium line of lever hoists is, and will likely remain, the most popular of these manual hoist options, it is important to cover the breadth of applications that place specific demands on this type of product.

The industrial line of lever hoists will always be a good choice if users already know the weight of the load. The premium line, meanwhile, is based on the same hoist but has overload protection. This has proved useful if the load weight is unknown, as the overload protection will activate at approximately 50% above the load rating. Dyno-Hoist, which eliminates the need for a separate shackle, dynamometer, and hoist, is the most technologically advanced of the range.

Steve Napieralski, president at OZ Lifting, said: “We are confident that expanding the industrial line to match the other two products will give distributors and their end customers all the capacities and technology options they need. As such, we do not anticipate expanding the range in the foreseeable future.”

The new industrial lever hoist range retains the features for which it has become renowned, including all-steel construction; 100% load-tested Grade 80 alloy chain; fully-enclosed gearing; long-lasting powder-coat finish; load sheave bearings; and more. Napieralski also pointed to the steel handle with rubber grip; forged alloy steel hooks; minimal load lifting effort; and heavy-duty latches. Custom options remain available.

Napieralski added: “There is still a big market for manual lifting products that don’t include overload devices or dynamometers. An end user might make a purchasing decision based on budget or application nuances—or maybe a little bit of both—but they will likely already know the weight of their load, meaning a dyno[mometer] is a completely redundant addition.”

The new 6-, and 9-ton capacity versions are already in stock and available for delivery.

“Business is excellent,” added Napieralski. “We have seen significant growth in all our product offerings.

A davit crane is making light work of lifting a dinghy for a boating enthusiast.

Troy Zerveskes recently refurbished a 30ft Luhrs Express Fishing Boat, which is now docked in Newington, New Hampshire. As part of the overhaul, he invested in a steel davit crane from Winona, Minnesota-based OZ Lifting Products.

“I wanted to have both a life raft and a dinghy onboard for additional safety as well as to explore some of the amazing islands we have,” said Zerveskes. “The steel crane from OZ Lifting Products was the most cost-effective option based on the budget we had.

“I use the davit to lift the dinghy onto the hardtop of my boat and it has worked really well so far. It allows me to have the additional safety and function that I need at a reasonable expense.”

Made in the USA, steel davit cranes from OZ Lifting Products have 360-degree rotation, four different boom height adjustments, and are available in multiple weight ratings from 500 lbs. to 2,500 lbs. They have an ROHS-compliant, zinc-plated finish and AC or DC winch options. The winch with brake includes a power drill adapter.

Davit cranes are typically more portable, versatile, and cost-effective than jib cranes. OZ Lifting Products manufactures steel and composite davit cranes for a wide range of industries and applications, including marine, oil and gas, and aviation, as well as construction, logistics, and transportation.

Zerveskes procured his steel davit crane through an authorized OZ dealer. It was ordered with a pedestal base, mounted with heavy duty bolts, but is also commonly used with a wall and socket mount, depending on the application. “The crane easily goes in and out of the base,” said Zerveskes. “Size and portability made the davit crane my preferred option. In the summer, I use it every week.”

Richard Miller, sales manager at OZ Lifting Products, said: “Our composite range of cranes might be more typically associated with the nautical and marine sectors, where they are often used to lift small sailing craft, jet skis, PWCs [personal watercrafts], etc., but this application serves as a good example of how diverse our steel davit cranes can be.”

OZ Lifting Products manufactures a wide range of hoists, winches, and davit cranes, as well as fall protection equipment, plus beam trolleys and clamps. Its products have provided safe lifting solutions in demanding applications for over 15 years, meeting or exceeding ASME, ANSI, OSHA, and other recognized standards.

The crane is installed on a recently-refurbished fishing boat.

OZ Lifting has launched a third lever hoist range—Dyno-Hoist, a dynamometer-equipped product from 0.75 to 9 tons capacity.

The Winona, Minnesota-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 premium (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.

Steve Napieralski, president at OZ Lifting, said: “There is nothing out there in the marketplace like this hoist. I don’t think there is a specific market for it, but we recently displayed it at two industrial trade shows and there was specific interest from the aviation industry, as they must tension parts for testing and need to know the exact weight. It will be useful in any application where you need to know the weight of the load being applied to the hoist. Where you would have previously needed to use a shackle, dynamometer, and hoist, with Dyno-Hoist, you gain a significant amount of headroom because the load cell is an integral part of the unit.”

OZ Lifting’s industrial line of lever hoists already offers a good choice if users know the weight of the load. The premium line, meanwhile, is based on the same hoist but has overload protection. This has proved useful if the load weight is unknown, as the overload protection will activate at approximately 50% above the load rating. Notably, Dyno-

Hoist’s dynamometer fitting itself can retrofit to either of the industrial or premium lever hoists. If a user has one of those models, they can purchase the load cell and complete installation.

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.

OZ Lifting will show a variety of davit cranes, hoists, and lifting components at this month’s Associated Wire Rope Fabricators (AWRF) Product Information Exhibition (PIE), which takes place at the Marriott Marquis Houston.

OZ Lifting has launched two spark resistant products—a chain hoist and push beam trolley—both available from 0.5-ton to 10-ton capacity.

The Winona, Minnesota-based manufacturer has targeted the products at applications where there are gas or dust particles that could create a spark. Typical markets include oil and gas, wastewater, paper, mining, and others where an explosive atmosphere exists.

The products are launched as a complete capacity range—0.5 ton, 1 ton, 2 ton, 3 ton, 5 ton, 10 ton—that covers most likely applications. As with other manual chain hoists in the catalog, 10 ft., 15 ft., 20 ft., and 30 ft. heights of lift are offered as standard, but custom lengths are available on request. All chain hoists and push beam trolleys are painted white, but distributors and end users might re-color them to suit protocols at specific facilities.

Steve Napieralski, president at OZ Lifting, said: “The products go hand in hand. We saw a need in the market for spark resistant manual chain hoists, and if you are going to offer them, you typically will be hanging the equipment from a trolley that also needs to be spark resistant. However, the products can work independently of each other. You might have a situation where the manual chain hoist doesn’t need to travel down an I-beam and is fixed in one location. And the trolley can accommodate either one of our manual spark resistant hoists or one that is powered.”

Explosive atmospheres
Potentially explosive atmospheres exist in many areas of industry. These explosive zones carry extremely strict guidelines and equipment requirements that standard catalog items cannot meet.

Both the new chain hoists and trolleys are manufactured in compliance with the EU’s explosion-proof standard ATEX94/9/EC and Machinery Directive 2006/42/EC. They can operate at explosion levels EX II2 GD c IIIC T135 C and are suitable for use in Zones 1 and 2 (gas) as well as Zones 21 and 22 (dust). The term “explosion proof” usually applies to electric-driven products, versus “spark resistant” for those operated mechanically, as Napieralski reiterated.

Key features of the hoists include unique hand wheel design; minimal load lifting effort; fully enclosed gearing; stainless steel or copper components; totally enclosed gearing; and suitability to lifting and pulling applications. The push beam trolleys, meanwhile, boast copper-plated trolley wheels and lifting bale; copper riveted identification tags; precision ball bearing trolley wheels; anti-drop plate; and compatibility with most I-, S-, and W-beams. Both products come with individual test certificate and serial number.

OZ Lifting will show its full range of davit cranes, hoists, and lifting components at MODEX 2022 (Booth B2926) on 28-31 March at Atlanta’s Georgia World Congress Center.
