Common Issues and Preventive Measures for Construction Hoists

Construction hoists, essential equipment in the construction industry, are prone to various issues due to factors such as aging, improper maintenance, and operational errors. This article delves into common problems associated with construction hoists and provides preventive measures to ensure their safe and efficient operation.

Common Issues

1. Equipment Aging:Over time, components like steel ropes, bearings, and electrical systems deteriorate, leading to potential safety hazards.
2. Inadequate Maintenance:Neglecting regular inspections and maintenance can result in equipment failures and accidents.  
3. Operational Errors: Lack of operator training or improper operation, such as sudden changes in working conditions or overloading, can damage the equipment.  

Preventive Measures

1. Strengthen Equipment Maintenance and Inspection:
   1. Conduct regular inspections and maintenance, emphasizing thoroughness and accountability.
   2. Promptly replace worn-out components and address any electrical issues.
   3. Ensure proper lubrication to minimize wear and tear.
   4. Strictly adhere to inspection and acceptance procedures after maintenance or modifications, as exemplified by the tragic incident at the Changsha Shanghai City project.
2. Enhance Operator Skills and Safety Awareness:
   1. Provide comprehensive training to operators, covering both theoretical knowledge and practical skills.
   2. Conduct regular skill assessments and safety education.
   3. Encourage operators to report any equipment abnormalities promptly.
3. Strictly Control Operating Conditions:
   1. Enforce strict limits on load, speed, and height to prevent overloading and overspeeding.
   2. Regularly inspect and maintain limit switches and safety devices.
   3. Prohibit the use of electric vehicles on the hoist and conduct regular inspections of fall arrest systems.
4. Establish a Comprehensive Equipment Management System:
   1. Clearly define maintenance responsibilities and create detailed maintenance plans.
   2. Establish a system for troubleshooting and resolving equipment failures.
5. Adopt Advanced Technologies and Management Practices:
   1. Utilize intelligent monitoring systems to track equipment conditions and detect anomalies in real-time.
   2. Implement IoT technology for remote monitoring and management.
