Outline of Crane Operator Training Labournet Correctly use and care for tools and materials which are required to carry out the normal service and maintenance of Mobile Cranes Operate and describe functions of the major and minor components of mobile cranes. Recognise and identify malfunctions and the proper procedures related thereto. Recognise and evaluate conditions which are potentially hazardous to safe operation. Interpret and apply load chart and related documentation. Work in conjunction and communicate with other trades, employers and customers. Interpret and apply visual and audio communication

Labournet Crane operation, to be safe and efficient, requires skill, the exercise of extreme care and good judgment, alertness and concentration, and a rigid adherence to proven safety rules and practices as outlined in applicable ANSI and OSHA safety standards. Few Safety Instructions Do not lift people and never ride the hoisting load. Do not lift load over people. No one shall be under the hoisting load. Make sure the sling is well balanced. Avoid tip loading, and loading on hook latch. Never lift the load over the rated capacity. Do not operate with kinked, twisted or damaged chain. Avoid side pull or end pull, and quick reversal operations. Never leave the suspended load unattended. Make sure you take up slack slowly.

Labournet Few Safety Instructions for Rigging Loads should be well secured. Slings should be adequate to the task. Slings should be un kinked and load balanced and secured. No sudden stops. No obstructions while lifting or traveling. No loose items on load or crane before lift. Bumping into runway stops is prohibited. Hoist line must be vertical prior to the lift (remove slack in the hoist slowly). No crane load should pass overhead of personnel, clear the area before making the lift. No one is to ride the crane without permission

Crane Operator Training Outli Labournet HOIST: With forearm vertical, forefinger pointing up, move hand in small horizontal circles. LOWER: With arm extended downward, forefinger pointing down, move hand in small horizontal circles. BRIDGE TRAVEL: Arm extended forward, hand open and slightly raised, make pushing motions in direction of travel. TROLLEY TRAVEL: Palm up, fingers closed, thumb pointing in direction of motion, jerk hand horizontally. STOP: Arm extended, palm down, hold position rigidly. EMERGENCY STOP: Arm extended, palm down, move hand rapidly right and left. An emergency stop signal must be accepted from any person. MOVE SLOWLY: Use one hand to give any motion signal and place other hand motionless in front of hand engaging in motion signal.

Outline of Crane Operator Training Labournet Cranes illustrate the use of one or more simple mechanism to create technical advantage. Lever -allows a heavy load attached to the shorter end of the beam to be lifted by a smaller force applied in the opposite direction to the longer end of the beam. Pulley -cables are wrapped multiple times round the fixed block and round another block attached to the load. When the free end of the cable is pulled by by a winding machine, the pulley system delivers a force to the load that is equal to the applied force multiplied by the number of lengths of cable passing between the two blocks. This number is the mechanical advantage. Cranes, like all machines, obey the principle of conservation of energy. This means that the energy delivered to the load cannot exceed the energy put into the machine. For example, if a pulley system multiplies the applied force by ten, then the load moves only one tenth as far as the applied force. Since energy is proportional to force multiplied by distance, the output energy is kept roughly equal to the input energy
