The construction and maintenance industries depend largely on aerial lifts, such as scissor lifts and boom lifts, to give workers safe access to elevated work areas. The safety and effectiveness of these machines have been greatly improved by recent technological developments and revisions to ANSI A92.20 design guidelines.
ANSI Standards for Improved Safety
Aerial lift safety elements have been improved due to many design-related advancements made to the ANSI A92.20 design standard for original equipment manufacturers (OEMs). These modifications are meant to lessen accidents and increase understanding of the new features and their use on the job site among operators, supervisors, and occupants.
ANSI standards’ main features are:
- The machine’s levelness is measured using an innovative component called an inertial measurement unit. Lift, telescope, and drive functions will all be automatically disabled if the equipment is not level when elevated, enabling secure operation even on uneven ground.
- A crucial safety element, load-sensing hydraulics, assesses the platform’s weight and protects against overloading. To reduce the danger of mishaps brought on by overloading, indicator lights notify operators if the platform exceeds its safe working load.
- MEWPs must now undergo wind stability tests and identification for operators to choose between “wind” and “no wind” settings based on exposure. This improves overall safety by reducing instability in strong winds.
- A guardrail height of 43.5 inches is now required by the standard, boosting accessibility and operator safety.
- Solid or foam tires are necessary for stability testing, adding an extra measure of security when in use.
- The revised guidelines also stress the value of appropriate training and yearly inspections to make sure that operators are prepared and that equipment is kept in good working order.
Advanced Techs Used in Aerial Lifts
- Motion and Load Sensing
load detection and motion sensing technology actively monitor the platform load of the machine and operator motions. This function helps to reduce the danger of collisions when operating in small areas or close to structures.
- Self-Leveling Technology
With this technology, the machine’s chassis adapts to the terrain automatically, removing the requirement to locate exactly level ground for safe operation. Self-levelling technology enhances the productivity and stability of construction equipment like aerial lift, crane and backhoe for sale while travelling, lowering operator fatigue and bouncing on hard or uneven terrain.
- Modern Sensor Technologies
Modern sensor technology, including SkySense from JLG, improves operator responsiveness in the workplace. The machine is slowed down and, if required, stopped as it approaches any obstacles due to these sensors’ visual and audible alerts. To gently move the machine closer to the work area, operators can override the mechanism.
- Mobile Applications
Some mobile apps are also enhancing the operator’s experience. Apps for augmented reality let users scan safety signs to find information on ANSI standards and display a control panel overlay with an explanation of the machine’s features. Some apps even allow for remote control, allowing for safer positioning and movement.
- Second Line of Defense
Systems for secondary security are becoming more and more commonplace. If the platform or operator comes into touch with an overhead impediment, these systems either actively or passively restrict or halt the machine. To identify obstructions and avoid mishaps, several systems including ultrasonics, radar, LiDAR, or other non-contact sensing techniques are also available in the aerial lift.
