Aerial lift safety

Aerial Lift safety:

Overview:

Aerial lifts are commonly used in construction, inspection, athletic events and repair services to lift University employees to an elevated work position. Proper operation and use of aerial lifts can make completion of tasks at elevation, safer and more efficient. However, unsafe use, operation and aerial lift work practices can result in serious injury. This program has been developed due to the hazards associated with improper use and the concern for the safety of individuals in and around this type of equipment. In addition, this program outlines general, operating, maintenance, inspection and training requirements governing safe aerial lift use.

Operate Aerial Lifts / Elevating Work Platforms must:

1. Select and then purchase or rent appropriate equipment for job tasks based upon an work environment and job-task hazard analysis,

2. Train and license personnel who operate their specific type of owned / rented equipment,

3. Conduct documented safety inspections and preventive maintenance of the equipment,

4. Assure operators adhere to specific safe-work practices whenever using these types of powered industrial equipment,

Definitions:

Aerial Device:  Any vehicle mounted or a self propelled device that is telescoping extensible, articulating, or both, and is primarily designed to position personnel.

AL / EWP: Acronym for “Aerial Lift/Elevating Work Platform”

Boom: An elevating member, the lower end of which is so attached to a rotating or non-rotating base that permits elevation of the free end in the vertical plane.

Counter Weight: The rear section or area of the lift which is usually made of solid steel, and/or combination of steel and the weight of the battery on electric lifts, that counter balances the boom leverage and basket load.

Data Plate: Manufacturer‟s equipment specification and information data, which includes basket load rating/lift capacity, lift heights, vehicle weight, and vehicle attachments. This plate is required to be affixed to all Aerial Lift Equipment by regulatory code. This is the vehicle operator‟s primary source of basic information about their vehicle for safe-work and use planning.

Emergency Lowering Means: Any elevating work platform equipped with a powered elevating assembly, and having a platform height exceeding 60 inches, must be supplied with safe means of lowering the basket or platform during an emergency or malfunction.

Fall Protection: An approved full-body safety harness with lanyard is to be worn at all times and attached to a secure anchor point when drivers or personnel are using a boom-type lift or vehicle mounted lift. Fall protection must also be worn when using scissor lifts on uneven surfaces or near locations with tip-over hazards.

Guard Rails: Railing around the perimeter of the work platform. This railing consists of a top rail between 39” – 45” with a mid-rail. Units with the top rail less than 39” must have fall protection in use to operate.

Lower Controls: Operating controls located on the base of the unit which can be switched to override the basket or platform control during an emergency.

Mast: Part of the lifting mechanism to which the hydraulic lift cylinder or worm drive is attached that supports the basket as it is lifted up and down.

Out Riggers: Extendable legs that are either manually set in place or, in some cases, hydraulically extended to give added stability to the unit base.

Platform: Any personnel carrying device (bucket, basket, cage, stand, tub, or equivalent) which is a component of an aerial device.

Upper Controls: Operating controls located on the basket or work platform of the unit. These controls can only be overridden with the operator‟s permission or in case of an emergency.

Requirements:

  • OSHA Standard 29CFR 1910.68 (Powered Platforms, Man lifts, and Vehicle-Mounted Work Platform)
  • OSHA Standard 29CFR 1926.453 (Aerial Lifts)
  • ANSI/SIA A92.6 – 2006 (Self-Propelled Elevated Work Platforms)


Types of Aerial Lift/Elevated Work Platforms

Articulating Boom Lift :

An aerial device with two or more hinged boom sections.

An articulating boom lift is a type of crane that uses hydraulic cylinders to rise and lower and allows a driver to maneuver the boom in any given direction directly from the work platform without lowering the basket. The articulating boom lift is specifically made with at least two boom sections that are hinged and it unhinges at certain points, this makes reaching higher elevations easier.

Articulating boom lifts typically operate with an electric motor or internal combustion as their powers source. It can not only rotate 360 degrees, but also access spots higher than most straight or telescoping boom lifts. They are narrow enough to be maneuvered easily through aisles and crowded work areas and are often found being used in construction, landscaping and plant maintenance.

Note: Fall Protection is required when operating this Lift.

Elevating Work Platform :

A device designed to elevate a platform in a substantially vertical axis. This device is stationary once setup and cannot be moved. Aerial or Personnel lift is an aerial lift that combines the portability of a ladder with the stability of an aerial work platform.

Simple to set up and easy to roll through doorways with a rigid vertical mast and leveling jack that offer stability for the user, the vertical mast raises the work platform to the desired height. Reaching heights of 47 feet and lifting up to 300 lbs, these personnel lifts are more stable than a ladder. It is ideal for indoor use and is suitable for fragile surfaces.

Note: Fall Protection is not required when operating this equipment, but is highly recommended.

Extensible Boom Platform :

An aerial device (except ladders) with an extensible boom. Telescopic booms with personnel platform attachments are considered to be extensible boom platforms. If you are looking for a boom lift with an extended reach capability then a telescopic boom lift is right for you.


Operable from the work platform, even when extended, some telescopic boom lifts are equipped with a jib that provides extra reach and range. Reaching up to 140' and offering a greater horizontal outreach than any other type of aerial platform, these boom lifts are often used in construction and industrial applications such as road building, bridge work, painting, and landscaping.

Note: Fall Protection is required when operating this equipment.

Scissor Lift :

A device designed to elevate a platform in a substantially vertical axis. This device can also be driven by an operator inside the work platform and is generally designed to carry more than one person. 

Also known as a table lift, a scissor lift is an industrial lift that has been modified for retail and wholesale setting. Powered by hydraulics, diesel or an electric motor, this lift will reach anywhere from 21 to 62 feet. It is basically a platform with wheels that acts like a forklift.Portable and effective, this is a lift is useful for completing tasks which require speed and mobility.

The scissor lift is unique in that it doesn't use a straight support to raise workers into the air, instead, the scissor lift platform raises when the linked, folding supports underneath it draw together, stretching it upward. The scissor lift's design keeps it from traveling with a constant speed, instead traveling faster in the middle of its climb and slower as it elevates. It can be seen in nearly all manufacturing and production workplaces, including construction, assembly, and vehicle repair.

Note: Fall Protection is not required when operating this Lift, but is highly recommended.

Trailer Mounted Lift :

A device that can be towed by a vehicle to a work site, then un-hitched. These units have extendable or folding outriggers to give stability while being operated. These are compact cranes that can lift up to 30,000 lbs. Designed for both indoor and outdoor job sites, these lifts feature telescoping booms and a load deck for material handling.

They are made for the work place and are self propelled, usually capable of picking up a load and traveling with it. The crane is equipped with a flat deck that is designed to be used as a carrying surface they are perfect for lifting applications requiring a compact, low-profile crane that will clear overhead obstructions and maneuver in tight spaces.

Note: Fall Protection is required when operating this Lift.

Vehicle Mounted Lift :

These devices typically have a Bucket in place of a basket, which is designed for one person. Vehicle must have the brakes set, wheels chocked, and outriggers in place while operating this device. Also  Frequently used by contractors due to their lightweight structure and maneuverability, they are ideal for congested job sites.

As the name states, tow able boom lifts are tow able, easily transportable and ready to use in minutes. Easy to maintain due to having less parts,they are easy to break down. Most have an articulating boom, but some models have a telescopic arm. They are light weight enough to use on lawns, slate, or gymnasium floors and are perfect for home renovations and property management needs.

Note: Fall Protection is required when operating this Lift.
