Safe Crane Operations

Safe Crane Operations

Safe crane operations include:

• Read and understand the operators manual
• Follow all placards, warning labels and signs on machine
• Know the SWL of the crane and never exceed it
• Determine the weight of the load from accurate sources
• If an estimate of the load is near the max. capacity of the crane, then use a dynamometer to measure the exact weight
• Use a loud signal, such as a whistle, horn or bell or verbal warning to alert employees of crane movement
• Never hoist a load over the heads of employees
• Never use limit switches or end stops as operating controls
• Begin each shift by testing the upper limit switches
• Avoid running the crane into the end stops or limit switches
• Never walk backward when guiding a load
• Never hoist two or more separately the capacity of the crane even if the combined weight is with in the capacity of the crane
• Never wrap the hoist line around the load
• Never electrical load and/or hoist-limit switches or warning devices
• Start lifts slowly and avoid shock loading
• Always place the hook directly over the center of gravity or the designated lifting point
• Use taglines to help maneuver the load
• Never use taglines to swing the load
• Before hoisting the load, check for loose parts that might shift or fall
• On cranes with wire rope hoist lines, there should never be less than two wraps on lagged (grooved) drums and three wraps on unlagged
• When lifting near or at capacity, test the brakes after the load is raised a few inches
• Suspend and transport loads at a level that allows the operator a clear view
• Never drag slings, cables or chains across the floor
