All preventive maintenance is important, but the manner in which your boom’s extend/retract cables are maintained is vitally important.
The boom extend/retract cables are responsible for the extension and retraction of the boom tubes depending on machine size. The maintenance of these items can have a profound effect on the safety and longevity of your Genie® boom-lift. For example, if the cables slacken, they can jump off the sheave resulting in damage to the cables and other boom components. Maintaining Genie products using the maintenance intervals in our Service and Maintenance Manuals will prevent this. Since most of the cable stretch takes place in the first year of service, the guidelines in our Service and Maintenance Manual recommends that the checking/tightening procedure should be performed quarterly for the first year the machine is in service, and then the procedure should be conducted annually after that.
With high rental utilization of your Genie Equipment, our maintenance protocols for boom cables were updated several years ago to offer you more equipment uptime and a lower cost of ownership over the potential life of your Genie equipment. The revised maintenance intervals for cable adjustment were updated to achieve two goals. First was to keep the cables and tubes in good working order, and the second was to ensure they weren’t being adjusted with more frequency than is required. Less time in the shop translates to more time out on rent. The updated maintenance intervals not only reduce downtime but also reduce labor costs by cutting out unnecessary work.
