Shropshire-based Garvey Demolition has made the switch to Lehnhoff products, benefiting from just a 15-second changeover between hydraulic attachments.
Garvey has invested in four Lehnhoff fully automatic Variolock quickcouplers for all its 22-tonne machines, and adapted 18 attachments: a mix of pulverisers, munchers, buckets and grabs. It has also added a Rotar rotating grab and an RDP32 pulveriser for its 50-tonne machine.
Oliver Barby, contracts and safety director, said he compared Lehnhoff with other quickcouplers available. His key considerations were safety, 15s changeover and no more broken pipes.
Variolock turns an hydraulic excavator into an all-round specialist machine by the easy and frequent changes of tools. Each attachment is ready for safe use in a matter of seconds, with the operator changing any tool, including the hydraulic connection, at the touch of a button from his cab.
Fully automatic changing of attachments offers a variety of benefits, such as increased efficiency by saving time and manpower; more efficient working as tool changes are viable even for short working cycles; safety and comfort for the operator; less contamination of the hydraulic system; and prevention of hydraulic hose failure.
Barby added: “Our 22-tonne machines make up about 40% of our fleet. We plan eventually to add Lehnhoff to our 14- and 50-tonne equipment as well. It is a big investment for us but, based on the quality of the product and the back-up from Worsley Plant, we are looking forward to reaping the future benefits.”
