4. การตั้งค่า

1. ตรวจสอบ: Before each use, thoroughly inspect the arborist block for any signs of damage, cracks, sharp edges, or excessive wear on the side plates, sheave, or axle. Ensure the screw-in top knob operates smoothly and locks securely.
2. Select Rope: Choose a rope with a diameter of up to 1/2 inch that is appropriate for the intended load and task. Inspect the rope for any damage or wear.
3. Open Block: Unscrew the top knob to open the side plate of the arborist block.
4. ใส่เชือก: Place the rope over the sheave (wheel) of the block.
5. Close Block: Close the side plate and securely tighten the screw-in top knob. Ensure it is fully engaged and cannot accidentally open during operation.
6. Attach to Anchor: Securely attach the arborist block to a suitable anchor point (e.g., a tree limb, rigging plate) using appropriate slings or connectors. Ensure the anchor point is strong enough to support the anticipated load.

5. คู่มือการใช้งาน

The CMI Micro Arborist Block is designed to facilitate efficient and controlled lowering or lifting of loads in tree care operations. Proper technique is crucial for safety and effectiveness.

1. การวางตำแหน่ง: Position the arborist block at the desired height and location on the anchor point. Ensure it is oriented correctly to allow the rope to run freely without obstruction or excessive friction against other surfaces.
2. Rope Management: Feed the working end of your rigging rope through the block. Ensure the rope is not twisted or tangled.
3. อุปกรณ์โหลด: Attach the load (e.g., cut branch) to the working end of the rope using a suitable knot or hitch.
4. Controlled Lowering/Lifting: Use a ground crew or mechanical advantage system to control the lowering or lifting of the load. Always maintain control of the rope to prevent uncontrolled descent.
5. Friction Management: Utilize appropriate friction devices (e.g., Port-a-Wrap, bollard) on the ground to manage the rope and control the speed of the load.
6. การสื่อสาร: Maintain clear communication between the climber and ground crew throughout the operation.

6. การบำรุงรักษา

• การทำความสะอาด: After each use, clean the arborist block to remove dirt, sap, and debris. Use mild soap and water, then rinse thoroughly and dry completely.
• การหล่อลื่น: Periodically lubricate the sheave axle with a light, non-corrosive lubricant to ensure smooth operation. Avoid over-lubrication, which can attract dirt.
• พื้นที่จัดเก็บ: Store the block in a clean, dry place away from direct sunlight, chemicals, and extreme temperatures. Protect it from physical damage.
• การตรวจสอบโดยละเอียด: Conduct a more detailed inspection periodically, checking for any signs of wear on the sheave, axle, side plates, and the screw-in top knob. Pay close attention to any areas where the rope makes contact.

7 การแก้ไขปัญหา

• Rope Jamming: If the rope jams, immediately stop the operation. Check for twists in the rope, obstructions, or improper seating of the rope in the sheave. Ensure the block is correctly aligned with the load path.
• Squeaking/Rough Operation: This may indicate a need for cleaning or lubrication of the sheave axle. Inspect for debris or wear.
• ความยากในการเปิด/ปิด: Check the screw-in top knob for dirt or damage. Clean and lubricate as necessary. Do not force the mechanism.
• ความเสียหายที่มองเห็นได้: Any visible damage such as cracks, bends, or deep gouges means the block must be immediately removed from service and replaced.
