Lippmann adds safety feature to jaw crushers

Milwaukee-based concrete crushing and recycling equipment maker Lippmann has made available what it calls a newly enhanced jaw safety pin the firm says underscores its dedication to workplace safety,

According to Lippmann, the pin is designed to lock the pitman (the main moving part in a jaw crusher) securely in the forward position during maintenance or repair. The company says the new pin is now available for retrofit “on select existing jaw models” and will be standard on future jaw crushers.

The firm’s jaw safety pin is designed to prevent accidental pitman movement, with Lippmann calling the new device “a critical safety feature during servicing.”

States the company, “With features such as a pinned locking mechanism and vertical storage location to prevent damage, Lippmann’s latest design aims to enhance safety while offering ease of use.”

“We've prioritized safety in all our designs, and the jaw safety pin is no exception,” says Danny McElchar, director of engineering at Lippmann. “While safety pins exist on other jaw crushers, we’ve responded quickly to customer feedback to make this feature available not just for future models, but as a retrofit kit for existing customers as well.”

According to Lippmann, its updated design includes a new hole on each side of the jaw box, a boss and a brace added to the jaw box rib. The company says some models will also incorporate a modified cheek plate or side liner to accommodate the new locking pin system, which Lippmann says allows for safe pitman positioning during service.

Additionally, decals provide “clear instructions on proper usage of the pin, ensuring operators are aware of the safety features,” states the equipment maker.

Lippmann, founded in 1923, provides aggregates processing equipment including primary jaw crushers, primary and secondary impact crushers and cone crushers, vibrating grizzly feeders, two-stage jaw and impactor crushing systems and ancillary products.
