Definition & types of Crane What is Crane? A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places . Types of Crane
Overhead Cranes Overhead cranes are used in many industries To move heavy and oversized objects that other material handling methods cannot. These cranes have a railed support structure, also known as a bridge, and a wheeled trolley that travels across the bridge horizontally. Several varieties of overhead cranes exist including gantry, semi-gantry, cantilever gantry, storage bridge and wall cranes.
Introduction/ Definition EOT Crane (electric overhead traveling crane) What is EOT crane? Electrical overhead travelling crane What Is Its Capacity? Its SWL- safe working load Eg . 5t, 2t, 32t, etc. Testing requirements? It is tested annually by competent person. It is compulsory by Local & International law.
Introduction Lifting Overview The lifting of objects generally occurs on construction sites, in factories, Plant and other industrial situations. Correct lifting can move large objects efficiently and reduce manual handling operations. However, Incorrect lifting can lead to disastrous accidents. Every year, incorrect lifting procedures cause injuries, loss of work time and property. People, machinery, loads, methods and the work environment, are all important factors for correct lifting. Provided that enough safety measures are fully implemented, lifting accidents can be reduced.
A rigging or lifting plan is developed every time a heavy load is being lifted. The basic idea behind a rigging plan is to have control and establish safety precautions. It is an important planning process that will identify all hazardous situations that might be encountered during lifting . Basics of Lifting What is Rigging/ Lifting Plan?
A permit-to-work system is a formal written system used to control certain types of work that are potentially hazardous. A permit-to-work is a document which specifies the work to be done and the precautions to be taken. Permits-to-work form an essential part of safe systems of work for many maintenance activities. Basics of Lifting What is permit to work system?
SWPs (Safe working procedure) are also referred to using other terms, such as Standard Operating Procedure . A SOP ( Safe Work Procedure) is a step by step description of a process when deviation may cause a loss. This risk control document created by teams within the company describes the safest and most efficient way to perform a task. Basics of Lifting What is SWP and SOP?
PPE is equipment that will protect the user against health or safety risks at work. It can include items such as safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses. It also includes respiratory protective equipment also Basics of Lifting What are PPEs?
Making the workplace safe includes providing instructions, procedures, training and supervision to encourage people to work safely and responsibly . Even where engineering controls and safe systems of work have been applied, some hazards might remain. These include injuries to: the lungs, eg from breathing in contaminated air the head and feet, eg from falling materials the eyes, eg from flying particles or splashes of corrosive liquids the skin, eg from contact with corrosive materials the body, eg from extremes of heat or cold PPE is needed in these cases to reduce the risk. Basics of Lifting Why PPEs are important?
According to the survey of accident Statistics ' & Census of Fatal Occupational Injuries , Several fatal occupational injuries found were related to cranes, derricks, hoists, and hoisting accessories in history. OSHA's analysis of crane accidents in general industry and construction identified an average of 71 fatalities each year USA. Basics of Lifting Crane Accident Statistics worldwide
Accidents related to cranes? While you are working around the crane you must know that 20 % to 25 % of all construction & Industrial fatalities are related to cranes Basics of Lifting
Crane accidents are one of the leading causes of construction workers’ deaths. Causes of these accidents include: Cranes buckling or collapsing. Weight exceed the capacity,, Balance of rigging , Balance of Out riggers, Unstable Ground Conditions. Improper employee training. Training. Improper coordination of rigging team, Understanding and Identification of hazards, safe distance between the crane operation and work performed by other workers. Mechanical failures. Poor Maintenance of lifting equipment mechanical failures. Lack of Lubrication. Contact with electrical Power lines. Electrocution, Inspections. Lack of thorough Examination and inspection from a competent person. Basics of Lifting Six basic things attributes the Crane Accidents

Pre-Operational Checks & Inspections INSPECTION CHECKLIST FOR EOT CRANE 1. Identify items that were inspected. 2. Show the status of the inspected items. 3. Provide the signature of the inspector. 4. Show the date. 5. File it and maintain it! Review the manufacturers specified inspection requirements! Basic inspection before prior to use
Pre-Operational Checks Inspection before use Visually inspect the runway system. Are all bolts in place? Are there any obstructions on the runway? Visually inspect bridge, trolley and hoist connections. Does everything appear normal? Visually inspect the mainline conductor bar system. Are the conductors aligned properly? Are all joint covers in place? Are there any broken or loose support brackets?
Hazard Crane Inspection activities are always hazardous Exposure to moving parts Under the Machinery Directive 2006 All moving parts must be covered Never touch moving part
Pre-Operational Checks Inspection before use Check for any loose or missing parts. Check end stops. End stops prevent the trolley from running off the beam. Know the location of disconnect switch that will cut the power off only to the hoist or crane. Be sure it is readily accessible and not blocked. Make sure wire rope is properly seated in its drum and sheave grooves without any slack or overlapping.
Electric Shock Hazard DANGER HIGH VOLTAGE Always Ensure Energy Sources Are Dissipated Before Initiating Any Maintenance Activity. 2 TON ACME CRANE Pre-Operational Checks Inspection before use
Pre-Operational Checks Inspection the system condition Inspect the control device to make sure all warning labels are in place and there are no cracks or missing bolts in the case .
Operational Inspection Does the “E” stop function correctly? Do all the directional buttons and motions function correctly? Test the hoist limit switches and any travel limit switches, if present, to ensure they are operating correctly. This should be done without load. If there are any horns or lights present, do they function properly? Do all motions of travel run smoothly with no unusual sounds present? Check the ground for any signs of oil leakage. Pick up a load and make sure the brakes are functioning properly. Operational Checks
Inspection Findings Do not Operate Tag out system If any damage or malfunctions are noted during the daily inspection, the operator shall immediately advise the appointed person so corrective action can be taken. If a malfunction occurs during operation , the operator shall immediately advise the appointed person so corrective action can be taken. If corrective action has not been completed by the end of the shift, the operator will advise the operator or operators of the next shift that corrective action is required and verify the crane is tagged out with an out of order sign or Do not Operate.
Operations Operational Instructions Associates in the direction of travel should be warned to move and remain clear of a lifted load at all times. Loads should not be suspended over personnel below. Under no circumstances may anyone ride the hook or load. Directional movement should be made smoothly and deliberately. Avoid rapid movements in any direction.
Operations Operational Instructions Under no circumstances may anyone ride the hook or load.
Falling and Failing the Load Never Position yourself under the load or between a fixed object and load Always use taglines for Load Movement 2 TON Operations Rigging, Slinging and lifting activities are always hazardous Never Position yourself or any person under the load or between a fixed object and load & never operate from the wheeled or movable place. Always use taglines for Load Movement
Operations Do not exceed the rated load capacity of the crane, hoist, chain, cable, slings, or other component. Slings, load chains and other lifting devices must be fully and securely seated in the hook before moving a load. Remove slack from the sling, chain, or cable before lifting a load. Operational Instructions
Operations Use the following Practices to avoid swinging the load Locate the hoist directly above the lifting point of the load before lifting. Lower loads directly below the hoist. Keep hoisting ropes vertical. Do not pull or push the load. Maintain two full wraps of cable on the hoisting drum.
Operations Use the following Practice to check the brakes When lifting loads at or near capacity, test the hoist brakes by returning the master switch or push button to the “OFF” position after raising the load a few inches off the floor. If the brakes do not hold, lower the load to the floor slowly and do not operate the crane. Report the situation immediately and DO NOT USE until repaired.
Operations Use the following Practice to raise the load Ensure that all loads are lifted high enough to clear obstructions before moving the bridge or trolley. Whenever possible, maintain a minimum clearance of one foot above loads and to the sides. Raise the load only to the height necessary to clear lower objects. Never pull a hoist by the pendant cable.
Operations Cautions Never leave the controls unattended while a load is suspended. If it becomes necessary to leave the controls, lower the load to the floor. Familiarize yourself with the location of the disconnect switch. If loss of electrical power occurs, place controls in the “OFF” position to prevent unexpected startup upon restoration of power.
Operations Use the following practice in power failure Disconnect power to a EOT Crane/ hoist that is unsafe or in need of repair. Arrange to have the disconnect switch locked and the control panel tagged with and “Out of Order” or “Do Not Operate” tag . Never operate a EOT Crane/ hoist that has been tagged with an “Out of Order” or “Do Not Operate” tag,
Hazard Rigging failure hazard Rigging is a critical part of lifting operations.... Improper rigging practices to lift the load can cause rigging failure. Rigging failure can expose riggers and other workers nearby to a variety of potential hazards and material or property loses.
Hazard Struck by hazard Struck by injuries produced by forcible contact or impact between the injured person and an object or piece of equipment. Struck-by hazards in construction cause accidents such as the following: A construction worker was hoisting bricks in a bucket to the top of a building.
Never Position yourself or any person under the load or between a fixed object and load & never operate from the wheeled or movable place. Always use taglines for Load Movement

A spreader beam is used to support long loads during lifts and to prevent the load from tipping, sliding, or bending. Lifting Beams It must be marked with minimum Serial No. & Safe working Load. Rigger must inspect physical condition of eyes, beam all welded part before and after use. Never overload more than capacity Always follow manufacturers instructions
There are various kind s of lifting clamps which are designed as per profile user. Lifting Clamps All lifting clamps must be marked with below details WLL/SWL Serial No Name of Manufacturer Date of Manufacture Size or Range of use CE mark Batch No
Before Lifting any object a rigger must know Lifting The Load Know the Weight Know the Capacity Retain the Load Control the Load
Types of hitches Slinging
Slinging
Center of Gravity Slinging Capture the Center-of-Gravity When the object is in suspended condition it always center itself under the lifting point Always center the lift above the center of gravity, not the physical center of the object
Center of Gravity Slinging
Center of Gravity Slinging The sling must not be attached to the load at a point lower than the loads center of gravity Exception to this rule when lifting loads on pallets or skids Then apex of sling must be above the center of gravity
Knowing the Gravity Center Slinging Marked on the load by manufacturer Located in catalogs or blueprints Some objects have lifting lugs Calculate or estimate it
