CIC ORIO Vefour integrated a second Verlinde VT3 wire rope hoist on an existing 10-ton overhead crane, to ensure synchronized lifting of long, fragile tubular parts using two hooks. The aim was to meet the requirements of standard EN 15011: simultaneous stop at end of travel and load summation. A lifting specialist for over 30 years, CIC ORIO Vefour builds custom and standard cranes, drawing on its expertise in steel structures and lifting equipment. It is the exclusive distributor of Verlinde hoist and overhead crane spare parts in the Rhône-Alpes and Provence-Alpes-Côte d'Azur regions.
The project was carried out for a well-known player in the design of high-voltage substations, who needed to lift long, tubular, fragile and expensive parts. "These parts need to be handled using two hooks, to avoid the complex manipulations involved in finding the center of gravity. This technical evolution aims to secure lifting and optimize production operations", explains Karl Pignata, Lifting Activity Manager at CIC ORIO Vefour.
The second hoist installed, Verlinde VT3, also 10 tonnes, was chosen for its identical performance to the existing model. The operation involved replacing the mechanical limiter with an electronic strain-gauge limiter, upgrading the drives to ensure communication between the two hoists, and integrating a finely-adjustable electronic limit switch.
The project took 8 days to complete, in a confined space, in a building classified as a "grey room", with an electric crane and staggered working hours.
