Cherry picker cranes, also known as boom lifts or aerial work platforms, are essential pieces of equipment for many industries. They are used to lift personnel to elevated work locations safely and effectively. In this comprehensive article, we will explore the cherry picker crane in detail, covering its types, components, applications, safety considerations, and maintenance tips, along with much more.
What is a Cherry Picker Crane?
A cherry picker crane is a type of aerial lift that consists of a platform or bucket at the end of a hydraulic arm. This crane allows workers to access heights for various tasks, such as construction, maintenance, and tree trimming. The name “cherry picker” comes from its original use in orchards for picking cherries and other fruits from tall trees.
Types of Cherry Picker Cranes
1. Telescopic Cherry Picker Cranes
Telescopic cherry picker cranes feature a straight boom that can extend and retract. These cranes are ideal for reaching great heights and are often used in construction and industrial applications.
2. Articulating Cherry Picker Cranes
Articulating crane booms consist of multiple sections that can bend and maneuver around obstacles. These are particularly useful in tight spaces or uneven terrain and are preferred for maintenance work on buildings.
3. Trailer-Mounted Cherry Picker Cranes
As the name suggests, these cherry pickers are mounted on trailers and are easily transported. They are suitable for temporary work sites and can be towed behind a vehicle for mobility.
4. Electric Cherry Picker Cranes
Electric cherry pickers run on batteries rather than fuel, making them a quieter and more environmentally friendly option. They are most commonly used for indoor applications.
5. Rough Terrain Cherry Picker Cranes
These cherry pickers are equipped with large tires and can navigate rugged outdoor conditions. They are often employed in construction sites with uneven ground.
Components of Cherry Picker Cranes
1. The Boom
The boom is the arm of the cherry picker that extends from the base to the working platform.
2. The Platform
The platform or bucket is where the operator stands to perform tasks at height. It typically has guardrails for safety.
3. The Controls
The controls are usually located in the platform and at the base, allowing both the operator and a ground person to manage the crane’s movements.
4. The Chassis
The chassis is the base of the cherry picker, which supports the weight of the crane and operator. Its design affects stability and maneuverability.
5. Stabilizers
Stabilizers are additional supports that provide stability to the crane when elevated. They are crucial for safety, especially in uneven terrain.
Applications of Cherry Picker Cranes
1. Construction Industry
Cherry picker cranes are widely used in construction for tasks such as framing, roofing, and installing lights or signage. They allow workers to access heights securely.
2. Maintenance and Repair
These cranes are commonly used in maintenance jobs for servicing buildings, power lines, and telecommunications towers.
3. Tree Care
Arborists use cherry pickers to safely trim or remove trees that are too tall or dangerous to climb.
4. Film and Visual Arts
In the film industry, cherry pickers are used for filming and photography at high angles, providing unique perspectives and shots.
5. Warehousing and Logistics
In warehouses, cherry picker cranes allow workers to easily reach high shelves and storage areas, improving efficiency.
Safety Considerations When Using Cherry Picker Cranes
1. Proper Training
Only certified operators should handle cherry picker cranes. Training ensures that operators understand the risks and safety measures associated with the equipment.
2. Regular Inspections
Before use, cherry picker cranes should undergo routine inspections to identify any potential mechanical failures. Check hydraulic systems, controls, and electrical components.
3. Use of Personal Protective Equipment (PPE)
Operators should wear appropriate PPE, including helmets, harnesses, and non-slip footwear, to ensure maximum safety while working at heights.
4. Assessing the Work Environment
Before operating a cherry picker, assess the worksite for potential hazards, such as overhead power lines, ground stability, and weather conditions.
5. Safety Protocols
Establishing clear safety protocols and ensuring all team members are aware of these protocols is vital for avoiding accidents.
Maintenance Tips for Cherry Picker Cranes
1. Daily Checks
Before use, conduct daily checks on the mechanical components, including boom functionality, hydraulic fluid levels, and tire conditions.
2. Regular Servicing
Schedule regular maintenance visits from certified technicians to keep the cherry picker in optimal operating condition.
3. Cleanliness
Keep the cherry picker clean of debris and dirt. This prevents wear and ensures optimal performance.
4. Check Fluid Levels
Regularly check hydraulic and engine oil levels and top them off as necessary to maintain proper function.
5. Documentation
Keep detailed records of all maintenance work and inspections performed on the crane, as this may be required for compliance with safety regulations.
Cost Considerations for Cherry Picker Cranes
1. Purchase vs. Rental
When considering a cherry picker crane, businesses must decide between purchasing or renting. Renting is often more cost-effective for short-term or one-off projects, while purchasing may be a better investment for long-term use.
2. Operational Costs
Operating costs include fuel or charging expenses, maintenance, insurance, and operator wages. Companies should consider these factors in their budget planning.
3. Resale Value
Cherry picker cranes often retain a decent resale value. Factors influencing this include the crane’s condition, age, model, and market demand at the time of resale.
Choosing the Right Cherry Picker Crane for Your Needs
1. Assessing Your Project Requirements
Determine the type of work to be done, required height, and specific conditions on-site to choose the right cherry picker type.
2. Weight Capacity
Evaluate the maximum load that the cherry picker can handle, including the operator and any tools or materials they will be carrying.
3. Maneuverability
Consider whether the crane needs to navigate tight spaces or rough terrain and choose a model designed for those environments.
4. Budget Constraints
Your budget will significantly influence your choice; include both acquisition costs and operating expenses in your calculations.
FAQ About Cherry Picker Cranes
1. What is the maximum height a cherry picker crane can reach?
Cherry picker cranes can reach heights ranging from 20 feet to over 150 feet, depending on the model and design specifications.
2. How long can a cherry picker crane operate on a single charge?
Electric cherry picker cranes can typically operate for about 8 hours on a full charge, but this can vary based on the load and usage conditions.
3. Do I need a license to operate a cherry picker crane?
Yes, in many jurisdictions, operators must have a specific certification or license to operate cherry picker cranes safely.
4. Are cherry pickers safe to use in high winds?
