Overhead cranes, including gantry cranes, are essential tools in many manufacturing, maintenance, warehouse, and industrial environments where heavy loads must be lifted and moved efficiently. While these cranes improve productivity, they also introduce serious hazards that can result in severe injuries or fatalities if proper safety procedures are not followed.
Crane operators, riggers, and employees working near overhead cranes must understand these hazards and follow established safety practices at all times.
Common Overhead Crane Hazards
The most frequent hazards associated with overhead and gantry cranes include:
- Caught-in or caught-between hazards
- Struck-by or struck-against incidents
- Crane overloading
- Falling or shifting materials
OSHA General Industry Standard 1910 Subpart N covers Materials Handling and Storage - Overhead and Gantry Cranes.
Training Requirements
To ensure everyone stays safe when cranes are in operation, only trained and authorized personnel should be allowed to operate any overhead crane.
OSHA General Industry Standard 1910.179(b)(8) Only designated personnel shall be permitted to operate a crane covered by this section.
Employees who work in the vicinity of overhead cranes must receive general safety awareness training so they understand crane hazards and know how to stay clear during lifting operations. Visitors should never be allowed near overhead cranes while they are in use.
Crane Inspections
Daily Visual Inspections
A basic crane inspection should be performed at the beginning of every shift or before the crane is used for the first time each workday. At a minimum, inspections should include:
- Surveying the area around the crane for leaks or trip hazards
- Verifying guards are in place and functioning properly
- Inspecting wire rope for damage or distortion
- Checking the drum for proper rope alignment
- Examining blocks and hooks for cracks or wear
- Inspecting bumpers for damage
- Testing limit switches for proper operation
If any defects are found, do not operate the crane. Report issues immediately and remove the crane from service until corrected.
Documented Periodic Inspections
In addition to daily checks, employers should implement a documented inspection program for more comprehensive periodic crane inspections, with written records maintained.
Personal Protective Equipment (PPE)
All crane operators, riggers and employees who work in the area where overhead cranes are in operation must wear the appropriate personal protective equipment, which may include:
- Hard hats
- Safety glasses
- Work gloves
- Hard-toe or safety-toe boots
PPE helps protect workers from falling objects, pinch points, and struck-by hazards.
Communication and Load Control
Hand Signals and Communication
Crane operators and riggers should be trained in standard hand signals, especially in situations where voice communication may be limited due to noise or distance.
Load Ratings and Capacity
Operators and riggers must know the crane’s rated load capacity. Load markings should be clearly posted on the crane and hoist block. Never attempt a lift unless the load weight is confirmed to be within rated capacity.
OSHA General Industry Standard 1910.179(n)(1) Size of load. The crane shall not be loaded beyond its rated load.
Operators must remain fully focused during lifting operations and avoid distractions that could divert attention from the load.
Safe Crane Operation Practices
Personnel must never leave crane controls unattended while a load is suspended. If it is necessary to leave the controls, lower the load first.
OSHA General Industry Standard 1910.179(n)(3)(x) The employer shall insure that the operator does not leave his position at the controls while the load is suspended.
- Never allow anyone to ride on a load or on the crane hook.
- Never carry loads over people.
- Use audible or visual warnings to alert workers in the area.
- Never walk under a suspended load.
- Remove all loose materials or parts from the load before lifting.
- Move crane controls slowly and avoid sudden acceleration or deceleration.
Maintenance and Lockout/Tagout
Only trained personnel may perform crane maintenance or repairs. Before maintenance begins, lockout/tagout procedures must be followed.
Do not operate any crane that is tagged out or marked “Do Not Operate.” Cranes with malfunctioning controls must be removed from service immediately.
Reinforcing Crane Safety Through Training
If overhead or gantry cranes are used in your shop, warehouse, or facility, regular safety meetings are essential. All employees working in crane areas should understand crane hazards, safe work practices, and their role in maintaining a safe workplace.
Consistent training, inspections, and communication help prevent serious incidents and ensure crane operations remain safe and efficient.
