What is an articulating manlift?
An articulating boom lift, also known as a knuckle boom, has a lift arm with multiple sections separated by joints, or “knuckles.” The arm can move the work platform over and around obstacles. The tallest articulating boom lift made today has a lift height of 150 feet and a 75-foot reach.
What is gradeability of a boom lift?
The new 450AJ boom lift from JLG features a platform capacity of 500 lbs. and 45% gradeability for improved rough terrain capabilities. With a larger work envelope on jib and non-jib models, the boom lift offers workers an extended reach that increases productivity.
Are scissor lifts safe?
Scissor lifts are very safe and secure. However, any equipment can be made unsafe if not used properly. In order to keep scissor lifts safe, be sure to always follow manufacturing instructions and maximum weight guidelines.
What is the difference between articulating boom lift and telescopic?
The best way to distinguish between these two types is this: Telescopic models are better for getting people and materials into place and holding them there, and articulating versions are better suited for moving people and materials around obstacles and into different positions with agility.
How does a telescoping lift work?
Telescoping boom lifts are also aerial work platforms. Unlike articulating boom lifts, however, the boom sections on this machine extend out and up. The machine uses hydraulics to extend or bring in two main sections, which makes the telescoping boom lift very stable.
What does gradeability mean?
steepness
Definition of gradeability : the steepness of grade that a motor vehicle is capable of climbing at efficient speed.
How is gradeability calculated?
The starting gradeability of a vehicle is the maximum gradient, on which the vehicle can start climbing from stand-still condition, with all the wheels of the vehicle on the gradient at the time of start. It is 100 x tan θ, where, ‘ θ ‘ is the angle between the gradient and horizontal plane.
Do scissor lifts fall over?
Have you ever wondered, “Can a scissor lift fall over?” The answer is yes. In fact, a man lift tip-over is one of the most common aerial lift accidents.
Do you have to wear a harness in a scissor lift?
Does OSHA Require Workers to Wear a Harness on a Scissor Lift? OSHA considers guardrails to be scissor lift fall protection. Assuming there’s an adequate guardrail system in place, scissor lift harnesses aren’t required by OSHA, but for all other situations, a personal fall restraint system is mandatory.
