OSHA requires certified training for any worker operating an aerial lift. This training can be done at an OSHA-approved facility or through a few online providers. Training is one of the biggest ways to prevent accidents on the worksite. Trained workers are generally more productive. They tend to cause fewer on-site accidents in the long run.
Genie offers a comprehensive online training program that can be purchased directly from 男女做爰视频免费播放_啪啪网视频. These web-based courses satisfy all OSHA, ANSI, and CSA requirements. The course is separated into two parts. The first is an online virtual training platform. With this platform option, operators learn safety protocols and how to operate controls safely. After the course is completed, students must pass a practical exam. Once the exam is completed, students only need an on-site refresher to be a certified operator.
The first company to make commercial scissor lifts offers a complete online experience. The immersive platform allows operators to get full training on the controls and safety procedures associated with aerial lifts. JLG also offers on-site courses with a trainer.
Allowing unlicensed operators to use machinery on your job site greatly increases your risk of accidents. Not only does this situation involve delays, but potential lawsuits, too. Insurance companies can deny any claims resulting from such accidents, and the state where you're operating can take away your license.
Charles Larson originally patented the movable scissor lift model we think about today in the 1960s. Prior to the X-shaped pantograph support pattern, lifts used a single post to raise platforms into position. The original design, however, dates from 1925. Historically, single-post lifts were challenging to use and relatively unsafe.
The modern scissor lift as we know them use a mechanism made of interlocking support that forms an X shape or pantograph. Lifting action is created when the support arms extend and make the pantograph narrower. Each pantograph moves in tandem, creating an even rise and stability from both sides of the platform. This mechanism was patented in 1966, and by the 1970s, it was in full production.
Larson's design for the pantograph scissor lift mechanism was so desirable that the design is still in use today. The double bar supports on each end of the platform allow for greater stability and security. The new support system permits the ability to use wider platforms and greater weight capacities than older single-mast platform lifts.
In 1976, JLG became the first company to offer the scissor lift commercially. After seeing the versatility of the lift, many other companies followed, including Meikikou in Japan, which released its N-Series in 1977. In 1998, JLG produced its 50,000th scissor lift.
Over the 50 years since Charles Larson patented the first scissor lift, companies and individuals have filed dozens of patents and designs for scissor lifts. While design patents related to powering the scissor mechanism have existed, Larson's design was so beneficial that few significant improvements to the actual pantograph design have been made.
The year 1975 brought one of the most significant enhancements to the electric scissor lift. In the original design, the hydraulic system in the lowest tier was mounted horizontally to align with the support bar. The redesign included a cylinder lift unit mounted at a fixed angle, which aligns the lift force with the vertical axis.
In 1987, the pantograph pattern was reduced in size and given personal use capabilities. The first screw-type scissor style jack patent was filed shortly after. This design became the industry standard for lifting cars, and a scissor jack general comes included with every new car bought in the United States.
Powered scissor lifts don't require any special equipment to move around the job site. Make sure you have enough space to maneuver before renting the equipment. The ease of operation comes with proper training.
