A 110V/60-Hz inverter is also available on all Genie electric scissor lifts, with an additional 230V/50-Hz inverter choice available for the two largest units, says Eric Ludwig, scissor lift product manager. On combustion engine models, there is an optional 2,000-watt generator. For the largest rough-terrain models, a welder option incorporates a 12,500-watt generator.
Skyjack also offers various power options on its new boom lifts. There is a basic 3,500-watt generator, plus a step-up option for a welder-ready machine that includes a 12,000-watt hydraulic generator with an oil cooler. For electric-powered scissor lifts, there is an optional 800-watt AC inverter and shop air line to the platform. Rough-terrain scissor lifts offer the shop air line, inverter and a 2,000-watt hydraulic generator.
Telehandlers as personnel lifts
Attachments are enabling telehandlers to expand their role on construction sites, as well. A number of attachments are available, such as brooms, truss booms, buckets and shovels. But for overhead work, the personnel work platform is the ideal accessory.
Dedicated boom or scissor lifts remain the preferred choice for most overhead tasks. Yet, there are circumstances where a telehandler equipped with a personnel work platform can be a viable option. For example, in extremely rough-terrain and/or sloping ground conditions, a telehandler can be used to lift workers to hard to reach areas that would be difficult or impossible to access with a boom lift. There may also be situations where it’s more cost effective or practical to simply swap out attachments, rather than bring both a telehandler and a boom lift to the jobsite.
Several independent manufacturers make personnel work platforms that fit on the forks of a telehandler. They are also offered by Gehl, JLG and Manitou for their own brands. Before buying any personnel work platform, determine whether the unit complies with ANSI/ITSDF B56.6-2005 standards.
Manitou offers four models of personnel work platforms for its rotating turret telehandlers (the cab and boom rotate as a unit). The platforms are internally wired with programming to operate the boom and safety features, such as lowering the boom if there is an engine failure. They also have a kill switch to stop all operations. According to Ryan Ford, Manitou construction telehandler specialist, 95% of the rotating turret telehandlers are purchased with the platform predispositioned, plus a control box.
Manitou also offers a fork-mounted platform for its conventional series of telehandlers with optional 180° swing carriage and wireless remote control boom. It does not allow the use of platforms on its lift trucks except for these specific models, and only when equipped with all of the required safety systems.
Gehl offers a fork-mounted personnel work platform, as well as two specialized platforms. One is a 180° swing work platform directly mounted on the boom. It allows workers to adjust the location of the platform to a comfortable and safe working position, even if the telehandler may not be able to be positioned correctly due to situations on the ground. The specialized platforms allow the worker in the platform to safely start/stop the telehandler’s engine, as well as raise/lower and extend/retract the boom without requiring a second operator to be in the cab of the machine.
JLG’s standard personnel work platform fits over the forks of all four of its telehandler brands (JLG, Gradall, Lull and SkyTrak). It features a removable front panel to allow operators to more easily get materials into and out of the platform. There is also a quick-switch model available for the JLG and Gradall brands that allows a rapid change from forks to a platform that directly attaches to the boom.
