OZ EXPANDS STAINLESS STEEL HOIST AND TROLLEY RANGE
hoist and trolley to its stainless steel range. Like other products in the line – including 0.5, 1.0 and 2.0-ton capacity versions – the new 0.25-ton version is designed for lifting and pulling. The hoist is said to be both lightweight
U
and durable, while the trolley fits most common I, S and W-beams. Steve Napieralski, president at Oz Lifting, said: “We have had a lot of inquiries for the 0.25 so we decided to add that to the line and, given that most of our sales are for both the manual chain hoist and trolley, it makes sense to continue to expand them together – at both ends of the capacity scale. In most instances, the products are used in lifting versus pulling applications, but the ability to do both remains a selling point.” There is no specific application for this
kind of manual hoist and trolley, beyond the fact that stainless steel is used in corrosive environments, including wastewater treatment plants, saltwater, or wash-down applications. Napieralski added: “We have a successful carbon steel hoist and trolley range [from 0.25 to 5.0 tons] – cost and application drive the decision whether that
would be sufficient or if the stainless steel alternative is more suitable. Stainless is typically two or even three times the cost of carbon steel, which is significant for certain end users, and carbon is perfectly adequate in numerous scenarios.” The stainless steel products require a similar maintenance programme as their carbon counterparts, Napieralski explained. He also stressed the importance of adhering to maintenance and inspection programmes, especially if the equipment is being operated in a highly corrosive environment. Oz Lifting outlines these requirements in an owner’s manual, included with every shipment, along with test certification. As the documentation states, the product meets a range of standards, including the American Society of Mechanical Engineers (ASME).

Napieralski said the Winona, Minnesota-based manufacturer has “several [new] products on the horizon in both steel types”. Both 3.0 and 5.0-ton stainless hoists
and trolleys are expected in the coming months. Discussions about stainless steel lever hoists are ongoing, while the company already stocks a range of stainless steel beam clamps. ●
COLUMBUS MCKINNON HOOK LATCH DESIGN WINS US PATENT
is used on the company’s Clevlok and Quick-Connect sling hooks. The slotted design enables the latch to be seated in the hook in a way that prevents disengagement or damage to the latch, ultimately keeping loads more secure, reducing the risk of damaged equipment and enhancing operator safety. Another feature of the design is a spring- biased safety latch that allows for installation onto the hook without spring tension, simplifying hook latch replacement in the field, according to Columbus McKinnon.

olumbus McKinnon, a designer and manufacturer of products and technologies for material handling, has been awarded a US patent for a slotted hook latch that
“Latches are often difficult to assemble, requiring the alignment of multiple components and screw installation while under spring pressure,” said Troy Raines, manager, rigging and chain products at Columbus McKinnon. “This can result in tired hands, lost components and multiple attempts at assembly to get components in place. With the slotted latch design, Columbus McKinnon has made this installation process easier.” Once the latch is assembled, a user can
pivot it past the hook tip to the closed position and tighten the screw. When tightened, the screw head and nut centre the latch in the hook and ensure the latch will not slip around the hook tip. The new design is protected by patent number 11,390,493. ●
