Aerial Platforms – Spider Lifts For High Rise Window Cleaning
Cleaning high-rise and commercial windows often requires access equipment that goes far beyond ladders or scaffolding. In Canada, aerial platforms are widely used for mid-rise buildings, industrial facilities, atriums, and select high-rise projects where rope access is not practical.
Choosing the right lift is not just about reach. It affects safety compliance, productivity, liability exposure, and overall project cost.
This guide explains the main types of aerial platforms used in window cleaning, when to use each one, and the safety standards that apply in Ontario and across Canada.
When it comes to window cleaning at elevation, not all platforms are created equal. Let’s explore the most common types you’ll encounter:
Spider Lifts: The Agile Climbers
Spider Lifts (Compact Crawler Lifts)
Spider lifts are designed for tight urban environments and delicate surfaces. They are commonly used for:
• Glass atriums
• Courtyards
• Interior malls
• Sensitive flooring
• Uneven terrain
Typical capabilities:
• Working heights exceeding 150 feet
• Horizontal outreach between 40–55 feet
• Narrow access entry points
Their stabilizing outriggers allow positioning close to façades while maintaining load balance.
Spider lifts are particularly useful in Toronto downtown cores where space constraints limit large equipment access.
According to Spimerica, spider lifts offer “safe and effective cleaning services for both interior and exterior window access.”
Scissor Lifts: The Steady Risers
Scissor lifts provide straight vertical elevation. They are stable and efficient but limited in horizontal reach.
Best used for:
• Flat façades
• Warehouses
• Enclosed industrial spaces
• Retail plazas
Advantages:
• Large stable platform
• Higher load capacity
• Ideal for repetitive vertical cleaning
Limitations:
• No extended outreach
• Not suitable for offset façades
They are practical for mid-rise commercial properties rather than tall high-rise towers.
Boom Lifts: The Flexible Reach Masters
Boom lifts are the most versatile aerial platforms in window cleaning.
They allow:
• Horizontal outreach around obstacles
• Up-and-over movement
• Access to recessed glass
Telescopic boom lifts provide extended reach, while articulating booms navigate complex architecture.
In urban commercial settings, boom lifts may reach between 70 ft and 180 ft depending on the model.
They are frequently used for:
• Multi-level commercial buildings
• Hotels
• Office towers below rope-access thresholds
Canadian Safety Requirements for Aerial Lift Operation
Operating mobile elevating work platforms (MEWPs) in Ontario requires strict compliance with workplace safety laws.
Under Ontario’s Occupational Health and Safety Act and related regulations:
• Operators must receive proper training
• Fall protection systems must be used
• Equipment must undergo regular inspection
• Hazard assessments must be completed before use
The Infrastructure Health and Safety Association (IHSA) provides guidance for working at heights and MEWP safety in construction and maintenance sectors.
In addition:
• Fall arrest systems must meet load capacity requirements
• Guardrails must be intact and secured
• Emergency descent procedures must be understood
Non-compliance increases legal and insurance exposure for building owners.
Critical Safety Features to Look For
When selecting an aerial platform for window cleaning, ensure it includes:
• Guardrail systems
• Load sensing technology
• Emergency lowering systems
• Automatic tilt detection
• Non-marking tires for interior work
• Stable outriggers
Proper setup on level ground is equally critical. Many lift incidents result from improper stabilization rather than equipment failure
Choosing the Right Platform for Your Project
1. Building Height
• Under 60 ft: scissor or small boom lift
• 60–180 ft: articulating or telescopic boom
• Higher elevations: rope access or building maintenance unit may be more appropriate
2. Ground Conditions
• Uneven terrain favors spider lifts
• Indoor retail flooring requires non-marking tires
• Tight downtown access may limit large equipment delivery
3. Pedestrian Traffic
In high-traffic Toronto areas, lift setup requires:
• Barricaded drop zones
• Spotters
• Off-peak scheduling
Public safety planning is part of professional operations.
The Benefits of Modern Aerial Platforms
Investing in advanced aerial platforms for window cleaning offers numerous advantages:
- Increased productivity
- Enhanced worker safety
- Improved access to difficult areas
- Cost-effectiveness in the long run
Environmental Considerations
While focusing on reaching those lofty heights, it’s crucial not to forget about Mother Earth. Here are some eco-friendly tips:
- Use biodegradable cleaning solutions
- Implement water-saving techniques
- Opt for energy-efficient equipment
Did you know? “Regular window cleaning can contribute to energy savings, especially during winter months,”
Training and Certification: The Key to Professional Operations
Operating aerial platforms isn’t child’s play. Proper training and certification are essential for:
- Ensuring operator safety
- Complying with regulations
- Maintaining equipment longevity
The Canada Department of Labor and Industry emphasizes the importance of following specific guidelines for the deployment and use of mobile elevating work platforms (MEWPs) in window cleaning operations.
Maintenance: Keeping Your Platforms in Top Shape
Regular maintenance is crucial for the longevity and safety of your aerial platforms. Here’s a quick checklist:
- Daily visual inspections
- Regular lubrication of moving parts
- Annual comprehensive checks
- Immediate repair of any damages
When Aerial Lifts Are Not the Right Solution
Aerial platforms are effective for many mid-rise and commercial projects. However, for very tall high-rise buildings in dense urban cores, rope access systems or permanent building maintenance units may offer better reach and efficiency.
Professional assessment determines the safest access method.
Why Professional Aerial Lift Window Cleaning Matters
Improper lift use exposes property owners to:
• Worker injury claims
• Public liability claims
• Regulatory penalties
• Insurance complications
Certified high-rise window cleaning companies carry:
• WSIB coverage
• Liability insurance
• Documented safety protocols
• Equipment inspection records
This protects building managers and commercial property owners.

FAQs
What is the safest aerial platform for window cleaning?
The safest platform depends on building design and conditions. Spider lifts and boom lifts offer stability and reach, but must be operated by trained professionals following fall protection standards.
Are aerial lifts safer than rope access?
Both methods are safe when used correctly. Aerial lifts are ideal for mid-rise or accessible ground conditions. Rope access may be more efficient for very tall high-rise façades.
How often should aerial lift equipment be inspected?
Visual inspections should occur daily before use, with scheduled servicing following manufacturer guidelines.
Do window cleaners need certification to operate lifts in Ontario?
Yes. Operators must be properly trained and competent under Ontario workplace safety regulations.
