Boom Lifts
One of the most common types of aerial work platforms is the boom lift. Boom
lifts come in many sizes and configurations to suit a variety of job site
needs. Smaller boom lifts have platforms that lift workers up to 30 or 40 feet
in the air, while larger boom lifts can reach heights of over 100 feet. Boom
lifts use hydraulic or electric systems to extend booms or arms out from the
vehicle/truck base with an elevated platform at the end for workers. This makes
them versatile for tasks like building inspections, window washing, and
building maintenance where different heights are required.
Scissor Lifts
Another popular
Aerial
Work Platforms is the scissor lift. Unlike boom lifts, scissor lifts do
not extend outward—instead, they raise vertically using scissor-like
mechanisms. This makes them well-suited for indoor environments or applications
where overhead clearances are limited. Scissor lifts are available in both
self-propelled and manual models, with maximum working heights from just a few
feet off the ground up to 70 feet or more. Common uses of scissor lifts include
trade show work, construction tasks, and facility maintenance.
Trailer-Mounted Lifts
For jobsites without easy truck access or long-term rental needs,
trailer-mounted aerial lifts provide a portable solution. These lifts are
mounted on trailers for transportation between locations. Once on site, the
lift and platform quickly raise using a hydraulic system mounted on the
trailer. Trailer-mounted lifts come in boom, scissor, and vertical types with
working heights from around 40 feet up to 110 feet or more. They are commonly
used in construction, facilities management, and tree care/logging
applications.
Vertical Lifts
Vertical lifts, sometimes called “spider lifts,” raise vertically like scissor
lifts but have multiple sets of articulating arms rather than scissor
mechanisms. This allows vertical lifts to position platforms in hard-to-reach
areas with limited overhead or floor space such as in and around buildings,
trees, or structures. They provide 360-degree user movement capabilities and
excel in intricate rigging and infrastructure inspection tasks. Vertical lifts
can reach heights comparable to traditional scissor lifts.
AWP Safety Considerations
While aerial work platforms provide an indispensable capability for working at
heights, they also carry inherent safety risks that must be properly managed.
Equipment operation training, fall protection use, and adherence to rated
capacity limits are essential. Some additional safety best practices when using
AWPs include:
- Inspecting lifts thoroughly before each use and correcting any defects. Never
operate malfunctioning equipment.
- Understanding machine load and environmental limits (e.g. wind speeds) to
avoid hazardous conditions.
- Wearing fall protection harnesses always secured to authorized anchor points
when in an elevated platform.
- Maintaining three points of contact when entering/exiting the platform and
wearing slip-resistant footwear.
- Avoiding contact with power lines and following clearance limits near
energized equipment.
- Using spotters when maneuvering equipment to prevent collisions with
obstacles and protect ground workers.
Industry Applications
Aerial work platforms find use across many industries thanks to their
versatility. Here are some of the major sectors that rely on AWPs:
Construction - Boom lifts, scissor lifts, and trailer-mounted lifts are
essential equipment at construction sites for tasks like drilling, welding,
ceiling grid installation, lighting/signage installation, surveying and more.
Facilities Management - Scissor lifts and small boom lifts allow interior and
exterior property maintenance including painting, lighting maintenance, HVAC
repairs, and more at commercial buildings and campuses.
Tree Care - Vertical aerial lifts, bucket trucks, and trailer-mounted lifts
enable safe pruning, trimming and removal of trees. This reduces risks versus
ladder use.
Infrastructure - Inspections, surveys, and repairs of bridges, cell towers,
smokestacks and other structures require boom, scissor and spider lifts for
close access.
Utilities - Bucket trucks in particular are necessary for electrical line work,
pole work, substation maintenance and other energy sector jobs. Aerial lifts
provide safe access for tasks.
Municipal - Cities and governments utilize boom lifts and trail cranes for
activities such as traffic signal repair, streetlight maintenance, and
park/field lighting installation and service.
The widespread adoption of aerial work platforms stems from the unmatched
capabilities they provide for working safely at height. With proper operation,
maintenance and safety compliance, AWPs empower workers across many job functions
with mobility, dexterity and fall protection not afforded by ladders, scaffolds
or other traditional means. They continue to evolve alongside technology to
affordably meet evolving industry needs.
