Sound a warning before moving the crane or when approaching personnel.
Always move toward the load and move slowly. Use a tagline to control the load.
Stay clear of the sheave wheels, holes, and lattice work in telescoping booms and other potentially dangerous areas
whenever the crane is in operation.
Pinch points are impossible to eliminate. Keep all portions of your body away from cable drums, sheaves, pulleys, lift
cylinders, and other moving parts of the crane. Be extremely careful when performing maintenance on the crane.
Use extreme caution when lifting with more than one hoist.
Do not strike any obstruction with the boom. If the boom should accidently contact an object; stop immediately. Inspect
the boom. Remove the crane from service if the boom is damaged.
Never push or pull with a crane boom.
Do not add to the counterweight to increase capacity.
When lifting loads, lift slowly and proceed with caution.
Maintaining a steady tension may free the load without shock loading the crane.
Cranes are designed and rated to handle freely suspended loads. Do not pull post, piling, or submerged articles that may
have a heavy accumulation of mud, silt, or sand.
When lifting loads, the crane will lean toward the boom and the load will swing out, increasing load radius. Ensure the
load capacity chart is not exceeded when this happens.
Check the swing brake. Make certain the swing brake operates correctly. Unexpected free swinging of a boom can be
dangerous.
Wind and other factors such as boom length, boom angle, size and weight of load being lifted, etc. can affect crane
stability and crane structures. Practical working loads for each particular job and lift shall be established by the user
depending upon conditions that exist at the time a lift is being made. Appropriate capacity reductions shall be made
whenever conditions indicate the possibility that a loss of crane stability or structural damage could occur. Be extremely
cautious if wind velocity approaches 20 miles per hour.
Exercise caution when swinging loads.
Never swing or lower the boom into the carrier cab.
Stop the hook block from swinging when unhooking a load.
Swinging rapidly can cause the load to swing out and increase the load radius. Swing the load slowly. Swing with
caution and keep the load lines vertical.
Operate the crane only from the crane operator's seat. Operating from any other position, such as reaching in a window,
constitutes a safety hazard.
