Routine maintenance of container shears

Container shears are heavy-duty industrial equipment primarily used to compress and shear various metal scraps (such as steel sections, plates, auto bodies, and lightweight materials) into high-density "blocks" for easier transportation, storage, and improved smelting efficiency.

Before starting work each day, the following checks must be performed:

1. Cleaning and Visual Inspection

Remove debris: Remove dust, oil, metal shavings, and other debris from the equipment surface, around the blades, and the feed chute. Keeping the equipment clean prevents debris from affecting cutting accuracy and damaging the equipment.

Visual Inspection: Visually inspect all parts of the equipment for obvious damage, cracks, or deformation.

2. Lubrication Check

Check Oil Level: Check that the hydraulic oil level in the hydraulic system is within the range specified on the oil level gauge. If the oil level is too low, add hydraulic oil of the same grade immediately.

Check Lubrication Points: Add an appropriate amount of grease or lubricating oil to all lubrication points specified in the equipment manual (such as slide rails, bearing seats, pins, etc.). Ensure that moving parts are well lubricated.

3. Fastener Inspection

Check Critical Bolts: Focus on checking the tightness of critical parts such as anchor bolts, blade fixing bolts, and hydraulic line joints to ensure there is no looseness. Looseness can lead to increased vibration, increased noise, and even accidents.

4. Electrical System Inspection

Inspect Wiring: Visually inspect cables and wires for damage, aging, or exposed wires.

Inspect Operating Buttons: Test the sensitivity and reliability of all operating buttons (such as start, stop, up, down). The emergency stop button must function effectively.

5. Blade Inspection

Inspect Blade Edges: Check the sharpness of the upper and lower blades, ensuring there are no chips, curled edges, or severe wear. Dull blades will reduce shearing quality and increase equipment load.

6. No-Load Trial Run

Before starting formal work, start the equipment and perform several no-load shearing cycles. Listen to the equipment's operating sound to ensure it is normal, and observe the hydraulic system for any abnormal vibrations or leaks. Work can only begin after confirming everything is normal.
