Boom Disassembly on a Skyjack SJB66TK Articulated Boom Lift

[MikePhua]

Skyjack SJB66TK articulated boom lifts are powerful machines used for reaching elevated work areas. Disassembling the boom is a critical procedure for repairs, transportation, or maintenance. This article discusses the step-by-step process involved in safely disassembling the boom of a Skyjack SJB66TK articulated boom lift, along with important safety precautions to ensure the work is done effectively.
Preparation Before Disassembly
Before beginning the disassembly of the boom, it’s essential to properly prepare the worksite and the lift itself. This includes:

1. Ensure Proper Stabilization: Position the boom lift on a flat and level surface. Engage the stabilizers to ensure that the lift is stable throughout the disassembly process.
   
2. Power Down the Equipment: Disconnect the power source by turning off the ignition and removing the key. This ensures that the system remains inactive and reduces the risk of accidental operation during disassembly.
   
3. Gather Required Tools: Prepare all necessary tools for the job, such as wrenches, impact tools, lifting equipment, and any required safety gear.
   
4. Check the Lift’s Manual: Consult the lift’s service manual to understand any manufacturer-specific procedures, torque specifications, or instructions related to the disassembly process.
   

Step-by-Step Boom Disassembly Process
Disassembling the boom requires careful handling of key components to avoid damage. Here is a general outline of the steps involved in disassembling a Skyjack SJB66TK articulated boom lift:

1. Lift the Boom to the Desired Position: Begin by extending the boom to a position that allows easy access to the parts that need disassembly. Ensure that the boom is securely positioned.
   
2. Remove the Hydraulic Lines: Disconnect any hydraulic lines that are attached to the boom. These could be for the tilt, lift, or other boom movements. Place them in a safe position to avoid damage or contamination. Use suitable containers to catch any leaking hydraulic fluid.
   
3. Disconnect Electrical Connections: Disconnect any electrical connections that are linked to the boom or controls. Ensure that wires are carefully labeled to make reassembly easier.
   
4. Detach Boom Pins: The primary structural components of the boom, including the arm and joint connections, are secured with large pins. Use appropriate tools to remove these pins. This step may require lifting equipment to support the boom once the pins are removed.
   
5. Support the Boom During Disassembly: As you remove each pin, ensure that the boom is properly supported. The lift's mechanical support arms may need to hold parts of the boom in place as each section is disassembled.
   
6. Remove the Boom Sections: Depending on the lift configuration, the boom may consist of multiple sections. Each section should be carefully removed by releasing the pins and lifting the sections one by one. You may need a crane or hoist for this step, especially for the larger sections.
   
7. Check for Wear or Damage: While disassembling, check for any signs of wear, damage, or corrosion in the hydraulic lines, electrical components, or boom structure. Document any issues to address during reassembly or repair.
   

Post-Disassembly Steps
Once the boom is disassembled, follow these post-disassembly steps:

1. Proper Storage of Parts: Place the boom sections and components in a safe, dry location to prevent further damage. Keep all small parts, such as pins, bolts, and fasteners, in labeled containers to avoid losing them.
   
2. Inspect Components for Serviceability: Thoroughly inspect each disassembled part for any wear, damage, or cracks. Parts that show signs of significant damage should be replaced to ensure the safety and functionality of the boom lift upon reassembly.
   
3. Clean the Boom: After disassembly, clean the boom sections and parts to remove dirt, grime, and debris. Cleaning will help ensure smooth reassembly and will allow for a more thorough inspection of the components.
   

Safety Considerations During Disassembly
Safety is paramount when disassembling a boom lift. Here are some important safety precautions to follow:

1. Personal Protective Equipment (PPE): Always wear the necessary PPE, such as gloves, safety goggles, steel-toed boots, and a hard hat, to protect yourself from potential hazards during the disassembly.
   
2. Use of Lifting Equipment: Make sure that lifting equipment such as cranes, hoists, or forklifts is in good condition and rated for the weight of the boom sections. Always follow safe lifting protocols to avoid accidents.
   
3. Hydraulic Fluid Management: Take care when handling hydraulic fluids. Have spill kits and absorbent materials available in case of leaks.
   
4. Working with Electrical Components: When disconnecting electrical components, ensure that all power sources are properly shut down and that any live circuits are safely handled.
   

Conclusion
Disassembling the boom on a Skyjack SJB66TK articulated boom lift is a complex but necessary task that requires proper preparation, the right tools, and adherence to safety protocols. By following these steps and guidelines, you can ensure that the disassembly is done effectively and safely. Always consult the equipment’s service manual for specific instructions, and remember that if you are unsure of any aspect of the procedure, professional assistance should be sought to avoid potential damage to the lift or harm to personnel.
