Selecting an Aerial Work Platform – Factors to Evaluate

Choosing the right Aerial Work Platform for a project depends on several technical and environmental factors. A careful selection process can improve work efficiency and reduce unnecessary equipment repositioning.

1. Required Height and Reach

Determine the maximum working height needed, including the worker’s standing height and arm reach. AWPs are categorized by platform height (distance from ground to platform floor) and working height (platform height plus operator reach, typically about 2 meters/6 feet). Also consider horizontal reach – boom lifts offer outreach beyond vertical limits, while scissor lifts provide only vertical movement.

2. Weight and Floor Load

Indoor work on suspended floors or mezzanines requires knowing the machine’s gross weight and the floor’s load capacity. Scissor lifts can be heavy; some compact electric models are designed for sensitive floor surfaces like finished concrete or epoxy. Check the ground pressure (measured in pounds per square inch or kilograms per square centimeter) for each model.

3. Power Source

• Electric (battery-powered): Quiet, zero local emissions, suitable for indoor use and noise-sensitive areas like hospitals or schools.
• Diesel or gas: Higher power and longer runtime, but produce exhaust and more noise. Better for outdoor rough terrain applications.
• Hybrid or dual-fuel: Available on some models for flexible operation.

4. Terrain and Slope

For outdoor job sites with uneven ground, gravel, or mud, choose rough-terrain AWPs with larger tires, oscillating axles, and higher gradeability (ability to climb slopes). Electric slab-scissor lifts are not designed for rough ground. Always check the maximum allowable slope – operating on a slope steeper than the machine’s rating can cause tip-over.

5. Dimensions for Access

Measure doorways, aisles, elevators, or loading ramps. Narrow vertical lifts or compact scissor lifts may fit through standard 30-inch (76 cm) doorways. Stowed height and width determine if the machine can be transported on a trailer or freight elevator.

A simple way to match an AWP to a job is to list the site conditions (indoor/outdoor, floor type, obstacles, slope) and the required vertical/horizontal reach, then compare against manufacturer specification sheets. Consulting with an equipment rental or sales specialist can help verify compatibility without relying on promotional claims.
