Choosing the Right MEWP: Types, Components, and Safety Features

Mobile Elevating Work Platforms (MEWPs) are essential in construction and maintenance, providing safe access to elevated areas. Their role is to enhance efficiency and safety on worksites by addressing accessibility challenges and meeting safety standards.

Understanding the types of MEWPs, their components, and safety features is important for selecting the right equipment. Let’s explore the different MEWP options and factors to consider for optimal performance and safety compliance.

Types of MEWPs

Selecting a Mobile Elevating Work Platform requires recognizing the distinct types available, each designed for specific operational needs and site conditions.

Scissor Lifts

Scissor lifts extend vertically through crisscrossing supports, offering a stable platform with a large work area. They are ideal for tasks requiring height access in both indoor and outdoor settings, such as installation and maintenance in confined spaces like warehouses. These platforms can support multiple workers and tools, enhancing productivity. Models vary in lift heights and weight capacities, with some reaching up to 60 feet. Electric scissor lifts are preferred indoors due to their non-emission engines, while diesel models are suited for rugged outdoor terrains.

Boom Lifts

Boom lifts provide both vertical and horizontal reach with an extendable arm, making them suitable for tasks like painting or exterior building repairs. Articulating boom lifts have jointed arms for navigating obstacles, while telescopic boom lifts offer straight reach for maximum height access. Available in electric and fuel-powered variants, these machines can extend over 180 feet. Features like four-wheel drive and oscillating axles enhance maneuverability and stability on rough terrains.

Vertical Mast Lifts

Vertical mast lifts are compact, single-person lifts designed for tight spaces and light-duty tasks, such as changing light bulbs or accessing narrow aisles. They offer a smaller footprint compared to other MEWPs, making them practical for confined areas. Generally, they extend up to 20 feet and have non-marking tires to protect indoor surfaces. Their compact design makes them suitable for smaller-scale projects.

Safety Features

Safe operation of MEWPs relies on integrated safety features. Operator training and adherence to safety protocols are foundational, but the design of these platforms includes measures to prevent accidents.

Guardrails provide a physical barrier to prevent falls, engineered to withstand significant force. Harness attachment points allow for personal fall protection equipment, creating a robust safety environment.

Emergency descent mechanisms enable controlled lowering of the platform in case of power failure, providing a fail-safe method to return to ground level. Tilt sensors and overload alarms alert operators to unsafe conditions, prompting corrective action before incidents occur.

Selecting the Right MEWP

Choosing the right MEWP involves evaluating project needs, site conditions, and the capabilities of different machines. Assess the work environment, considering terrain type, indoor versus outdoor settings, and obstacles to determine the optimal reach and maneuverability required.

Evaluate load requirements, including personnel, tools, and materials, to select a MEWP with the appropriate weight capacity. This ensures efficient and safe operation, preventing equipment failure or accidents.

Consider the frequency and duration of use. For prolonged usage, fuel efficiency and battery life are critical. Electric models offer reduced emissions and quieter operation, ideal for residential or noise-sensitive areas. Diesel-powered options provide robust performance for extended outdoor tasks.
