Колико често треба прегледати мостне дизалице?

Инспекција надземне дизалице је једна од најкритичнијих пракси за безбедност на радном месту, усклађеност са прописима, and equipment longevity. Whether you run a manufacturing plant, складиште, construction site, or logistics center, knowing the correct inspection schedule protects your team, reduces downtime, and avoids costly violations. In this post, we break down how often overhead cranes should be inspected based on industry standards and best practices.

Why Overhead Crane Inspection Is Non-Negotiable

Мостне дизалице handle heavy loads in demanding environments. Носити, умор, корозија, and mechanical failure can develop slowly but lead to serious accidents. Regular overhead crane inspection:

• ◆ Prevents injuries and downtime
• ◆ Ensures compliance with OSHA, АСМЕ, and local regulations
• ◆ Extends the service life of hoists, bridges, end trucks, и контроле
• ◆ Reduces long-term repair and replacement costs

No matter how new or reliable your crane seems, skipping inspections creates unnecessary risk.

Standard Overhead Crane Inspection Frequencies

Industry guidelines (ОСХА, ASME B30.2, CMAA) divide overhead crane inspection into two main categories: frequent inspections and periodic inspections.

1. Честе инспекције (Daily to Monthly)

These are visual and functional checks performed by operators or trained maintenance staff.

• ◆ Daily / Shift Inspection: Пре сваке употребе, check hooks, ropes, ланци, кочнице, крајњи прекидачи, контроле, and abnormal sounds.
• ◆ Monthly Inspection: Documented detailed check of wear components, hydraulic/pneumatic systems, реевинг, and safety devices.

2. Периодичне инспекције (1–12 Months)

These are comprehensive inspections performed by a qualified person or certified technician. Frequency depends on usage severity:

• ◆ Normal service: Annually
• ◆ Heavy service: Semi-annually to annually
• ◆ Severe service (continuous use, harsh environment): Quarterly to semi-annually

All cranes require at least one full periodic inspection per year.

When to Inspect Immediately (Outside the Schedule)

You must perform an immediate overhead crane inspection if:

• ◆ The crane was involved in an impact, overload, or near-miss
• ◆ Unusual noises, jerky movement, or loss of control occur
• ◆ The crane has been idle for a long period
• ◆ After repairs, modifications, or reinstallation

Never operate a crane that fails any inspection step.

Key Items Covered in Overhead Crane Inspection

A complete inspection covers the entire system:

• ◆ Crane hooks, резе, and lifting attachments
• ◆ Wire ropes, ланци, and slings
• ◆ Brakes, clutches, and drive systems
• ◆ Bridge, end trucks, and runway rails
• ◆ Electrical components and controls
• ◆ Limit switches and safety devices
• ◆ Structural integrity for cracks, деформација, или корозије
• ◆ Lubrication and bolt tightness

Documentation is mandatory for compliance.

How to Build a Compliant Inspection Plan

• 1. Follow OSHA and ASME requirements for overhead crane inspection frequency.
• 2. Adjust intervals based on usage, животне средине, and load intensity.
• 3. Train operators on daily checklists.
• 4. Use certified inspectors for annual/periodic checks.
• 5. Keep digital or physical records of all inspections.
• 6. Schedule maintenance immediately after defects are found.

Колико често треба прегледати мостне дизалице? The short answer: daily by operators, monthly in detail, and at least annually by a qualified inspector — with more frequent checks for heavy-use equipment.

Overhead crane inspection is not just a regulatory box to check; it is a foundational safety practice. A consistent, well-documented inspection program keeps your operation safe, ефикасан, and reliable.
