When it comes to working at height, two terms that often arise are cherry picker and MEWP. For the uninitiated, it might seem like these terms are interchangeable, but in reality, they represent distinct types of equipment for different purposes. In this blog, we aim to shed light on the differences between these two aerial work platforms, exploring their functionality, features, and applications. Whether you're a construction professional or simply curious, join us as we unravel the mystery behind cherry pickers and MEWPs.
1. Understanding Cherry Pickers:
A cherry picker is a type of hydraulic crane equipped with a bucket or platform to raise workers and materials to elevated heights. Derived from its initial use in orchards for picking cherries, these machines have evolved into versatile lifting platforms widely employed in various industries. Boasting a boom arm and a basket, a cherry picker provides easy access to high areas while ensuring security and stability.
Despite their name, cherry pickers are not limited to orchard work. Their adaptability makes them indispensable for activities such as construction, utility maintenance, and outdoor filming. Offering a wide range of vertical lift and outreach options, cherry pickers are excellent for jobs that require precise positioning or overcoming obstacles.
2. Decoding MEWPs:
On the other hand, Mobile Elevating Work Platforms (MEWPs) encompass a broader category of aerial work platforms that include cherry pickers. MEWPs consist of various machines, such as scissor lifts, boom lifts, and aerial platforms, all designed to provide safe and efficient elevation access. Unlike cherry pickers, which have specific specifications, MEWPs are a diverse range of equipment tailored to different job requirements.
Scissor lifts, for instance, employ crisscrossing supports to raise and lower platforms vertically. These are ideal for situations where a larger working area is necessary, such as installing air conditioning or reaching high ceilings. Boom lifts, similarly, utilize hydraulic or articulating arms to extend both horizontally and vertically, offering the flexibility to access difficult-to-reach places.
3. Key Differences and Applications:
Now that we understand the basics, let's dive into the key differences between cherry pickers and MEWPs:
a. Stability and Height: Cherry pickers typically feature large, stable bases to withstand uneven ground conditions. They excel in providing access to extreme heights, often surpassing 100 feet. MEWPs, including scissor lifts, are generally more stable and used for accessing moderate heights, typically ranging from 20 to 50 feet.
b. Maneuverability and Reach: MEWPs offer greater maneuverability due to their compact size and design. They can navigate tight spaces and narrow corridors. Cherry pickers, with their impressive horizontal outreach capabilities, are specifically intended for tasks requiring extended reach and lateral mobility.
c. Terrain Adaptability: While cherry pickers are often deployed in open spaces or outdoor settings, MEWPs can easily navigate both indoor and outdoor environments. Scissor lifts, with their non-marking tires and electric power options, are particularly suitable for quiet and precise indoor operation.
4. Safety First:
Both cherry pickers and MEWPs prioritize safety as a key aspect of their functionality. Manufacturers adhere to strict quality standards, ensuring the equipment is built to withstand various operational challenges. Integrated safety features, such as emergency stop buttons, fall arrest systems, and stability locks, further safeguard workers.
However, industry professionals must receive proper training and certification to operate these machines proficiently. Organizations like the International Powered Access Federation (IPAF) offer comprehensive programs to equip individuals with the necessary skills for safe and efficient MEWP handling.
Conclusion:
In summary, while cherry pickers are a subset of MEWPs, each type serves unique purposes depending on the nature of the task at hand. Understanding their differences helps professionals select the most suitable equipment, ensuring productivity, safety, and efficiency on the worksite.
Next time you find yourself in need of an elevated work platform, whether you require extended reach or a smaller working area, you will be equipped with the knowledge to choose between a cherry picker or a specific type of MEWP. Remember, safety should always be the highest priority, regardless of the equipment used.
