Scissor & Boom Lift

Aerial Platform Lifts (A.P.L.) : Scissor lift and Boom Lifts are reliable mobile elevating work platforms used by workers to reach elevated work locations in a variety of industries and applications. A.P.L. safety requires careful consideration of the equipment specifications and standardizing safe operator practices through effective training.

According to an OSHA study, the three largest issues contributing to A.P.L. injuries and deaths were employers’ failure to address:

  • Fall protection
  • Stabilization
  • Positioning

In order to protect associates from safety hazards linked with these three areas, employers must ensure that only properly trained operators are permitted to use the lifts. Operators should be able to demonstrate proper use of the lift. Trained associates should complete pre-operation checks of the A.P.L., follow manufacturers’ instructions, use personal protective equipment (PPE) where required and ensure any maintenance needs are addressed before use.

Fall Protection

Guardrails are required to be installed on A.P.L.s to prevent falls. Operators should always check guard rails prior to operation of the A.P.L., never stand on the guard rails and never lean over the guardrails to reach tasks.

Stabilization

Stability of the A.P.L. work platform is essential for safety. To reduce the risk of tip-overs, operators and employers should:

  • Isolate the A.P.L. from traffic and other moving worksite equipment to prevent impacts
  • Ensure work locations have a firm, level surface away from hazards
  • Only use the equipment when weather conditions meets requirements labeled on the equipment or found in the operator’s manual.

Positioning

A.P.L. operators should be aware of hazards that can contribute to tip overs, crushing and electrocution. Operators should exercise the utmost caution when:

  • Operating a A.P.L. near a stationary object
  • Operating closely with mobile equipment
  • Passing below fixed objects like door frames and ceiling beams

Due to risks with arcing electricity, operators should not use A.P.L.’s within 10 feet of power lines, transformers or other utilities. If the job absolutely requires work near these electrical sources, the worker should be properly trained and certified and the utility provider should be contacted before work begins.

Maintenance

In addition to regular, planned maintenance, A.P.L.’s must pass a pre-operation inspection. Operators should inspect and test controls and components, inspect guardrails and ensure brakes are set properly before each and every use. Daily pre-inspection items can be found in the operator’s manual.

How can we reduce the risk of an Aerial Platform Lift collapse?

Risk of a A.P.L. collapse can be reduced by by:
  • Completing proper maintenance of safety systems
  • Keeping weight on work platform below manufacturer’s rated limit
  • Never using equipment aside from the A.P.L’s mechanisms for raising the work platform
  • Isolating the A.P.L. from traffic and other moving worksite equipment to prevent impacts

What are the types of Aerial Platform Lifts?

Aerial devices were once exclusively operated by hydraulic pistons, powered by diesel or gasoline motors on the base unit. Lightweight electrically powered units are gaining popularity for window-cleaning or other maintenance operations, especially indoors and in isolated courtyards, where heavier hydraulic equipment cannot be used. Aerial devices are the closest in appearance to a crane- consisting of a number of jointed sections, which can be controlled to extend the lift in a number of different directions, which can often include "up and over" applications. This type of AWP is the most likely of the types to be known as a "cherry picker", owing to its origins, where it was designed for use in orchards (though not just cherry orchards). It lets the picker standing in the transport basket pick fruit high in a tree with relative ease (with the jointed design ensuring minimum damage to the tree). The term "cherry picker" has become generic, and is commonly used to describe articulated lifts (and more rarely all AWPs). This type of AWP is now widely used for maintenance and construction of all types, including extensively in the power and telecommunications industries to service overhead lines, and in arboriculture to provide an independent work platform on difficult or dangerous trees. A specialist type of the articulated lift is the type of fire apparatus used by firefighters worldwide as a vehicle to provide high level or difficult access. These types of platforms often have additional features such as a piped water supply and water cannon to aid firefighters in their task. Some articulated lifts are limited to only the distance accessible by the length of each boom arm, however, by the use of telescoping sections, the range can be vastly increased. Some large hydraulic platforms mounted on a lorry can reach heights of over 100 metres.[3] The majority of articulated lifts require a wide supportive base to operate safely, and most models have extending legs/struts to help accomplish this. These legs can be manual or hydraulic (usually depending on size and price of the machine). Some AWPS are classified as "spiders" due to the appearance of these legs. Spiders are also available in especially compact form, to fit through doorways for use inside
