Hand-operated hoist safety violations: Case studies

As a common lifting device, the hand-operated hoist is widely used in industrial production and construction. However, due to improper operation, inadequate maintenance, or rule violations, safety issues may arise during its use. This paper illustrates several typical cases to highlight critical safety concerns associated with hand-operated hoists.  

Case 1: Overloading 

At a construction site, workers overloaded the hoist with materials exceeding its rated capacity to expedite project timelines. During lifting, the chain snapped due to excessive strain, causing materials to fall and resulting in severe injuries. This case underscores the necessity of adhering to the hoist’s rated load capacity.  

Case 2: Lack of Regular Inspections and Maintenance 

In a factory, prolonged neglect of inspections led to rusted chains and worn bearings. During a lifting operation, component failure caused cargo to drop, resulting in significant economic losses. This highlights the importance of routine checks and maintenance to ensure safety and reliability.  

Case 3: Unauthorized Use of Lifting Straps 

At an engineering project, workers substituted lifting straps for the hoist’s dedicated hooks for convenience. The straps, differing in material and strength, broke during lifting, causing materials to fall and severe injuries. This case emphasizes that hooks must not be replaced with unapproved materials.  

Case 4: Absence of Safety Training 

At a chemical plant, operators lacking proper training mishandled the hoist, ignoring safety ropes. A malfunction led to cargo falling and serious injuries. This underscores the critical need for safety training to ensure operators understand correct usage and precautions.

These cases reveal key safety considerations for hand-operated hoists: avoiding overloading, conducting regular inspections, prohibiting unauthorized lifting equipment substitutions, and mandating safety training. Addressing these issues ensures safe and reliable operation, protecting both equipment and personnel.
