Shaker users must be able to rely on a very high level of system reliability, both mechanically and electronically. To guarantee this reliability, the purchase of a shaker is accompanied by a carefully considered and progressive maintenance contract.
Wilfried Lacavelerie, in charge of the installation and who carries out on-site maintenance for SMAC, tells us about his work, “I always start by talking to the users of the shaker to find out details of the tests they perform and their duration, and I make a note of all the incidents. I then carry out an initial low-level test (2 g) over the entire frequency range of the shaker. This test is called a signature and is repeated at the end of the maintenance session, which lasts approximately three days for a V8 system. This serves as a reference and allows us to detect gaps between parts and parasitic movements of the coil.
After dismantling, I check the condition of the parts such as the suspensions, bearings, and the various joints of the shaker. If I find little or no traces of wear and dust, I adapt the service. We have Bronze, Silver, Gold and Platinum maintenance contracts, which may or may not include certain consumables, up to a spare mobile coil in stock. We can then agree to change a given part during the next maintenance. On the other hand, certain elements, such as oil filters, are changed systematically, regardless of the type of contract.”
