CEPC0502 ADVANCED CONSTRUCTION METHODS & EQUIPMENT 04 Lifting and Hoisting Equipment | Page 6 of 21 4.1.2.1 Lever Principle: Principle: Cranes use the principle of the lever, where a load is lifted using a boom or arm that acts as a lever. The fulcrum is the crane's base or pivot point. Application: By adjusting the length of the boom and the position of the load, cranes can lift heavy objects with relatively less effort. 4.1.2.2 Counterweight: Principle: To balance the load being lifted, cranes use counterweights. These are weights placed opposite the load to ensure stability and prevent tipping. Application: Counterweights are crucial for maintaining the crane's balance, especially when lifting heavy or off-center loads. 4.1.2.3 Hoisting Mechanism: Principle: The hoisting mechanism, which includes the winch, drum, and ropes or chains, raises and lowers the load. This mechanism converts mechanical power into vertical movement. Application: Proper maintenance and operation of the hoisting mechanism ensure smooth and reliable lifting and lowering of loads. 4.1.2.4 Boom Mechanics: Principle: The boom, or arm, of a crane can be extended, retracted, or angled to reach different positions. The design and operation of the boom affect the crane's reach and lifting capacity. Application: Operators must understand the boom's mechanics to optimize reach and lifting capabilities while ensuring safety. 4.1.2.5 Rotation and Movement: Principle: Cranes are equipped with mechanisms to rotate the boom and move the crane horizontally. This allows for precise positioning of loads. CEPC0502 ADVANCED CONSTRUCTION METHODS & EQUIPMENT 04 Lifting and Hoisting Equipment | Page 7 of 21  Application: Understanding rotation and movement controls is essential for accurate placement of loads and efficient crane operation. 4.1.3 Key components and features Understanding the key components and features of cranes is crucial for effective operation, maintenance, and safety. Cranes are complex machines with several critical parts that work together to lift and move heavy loads.

It extends and retracts to adjust the crane’s reach and lifting height. Types: Fixed Boom: A non-adjustable boom, usually found in tower cranes. Telescopic Boom: A boom that extends and retracts like a telescope, providing variable reach. 4.1.3.2 Jib: The jib is an extension of the boom that allows for greater reach and flexibility. It is found on cranes like tower cranes and mobile cranes. Types: Horizontal Jib: Stretched out horizontally from the main boom. Lattice Jib: Made of a lattice structure to provide strength and reduce weight. 4.1.3.3 Counterweights: Counterweights are used to balance the crane and prevent tipping when lifting heavy loads. They are placed on the opposite side of the load. Types: Fixed Counterweights: Permanent weights that are part of the crane’s design. Adjustable Counterweights: Weights that can be added or removed based on the load. CEPC0502 ADVANCED CONSTRUCTION METHODS & EQUIPMENT 04 Lifting and Hoisting Equipment | Page 8 of 21 4.1.3.4 Hoist: The hoist is the mechanism that raises and lowers the load.

It can be mounted on the crane’s track or rail system. Types: Bridge Trolley: Moves along the rails of an overhead crane. Lattice Trolley: Moves along the lattice structure of a lattice boom crane. 4.1.3.6 Rotation Mechanism: This mechanism allows the crane to rotate horizontally, providing 360-degree movement around its base. Components: Slewing Gear: The gear system that controls the rotation of the crane. Turntable: The platform that rotates to change the crane’s direction. 4.1.3.7 Outriggers: Outriggers are extendable supports that stabilize the crane and prevent tipping during operation. They are deployed outward from the crane’s base. Types: Manual Outriggers: Requires manual deployment and adjustment. Hydraulic Outriggers: Automatically extend and retract using hydraulic systems. CEPC0502 ADVANCED CONSTRUCTION METHODS & EQUIPMENT 04 Lifting and Hoisting Equipment | Page 9 of 21 4.1.3.8 Cab: The cab is the enclosed area where the crane operator controls the crane. It houses the controls and instruments. Features: Control Panel: Contains switches, levers, and displays for operating the crane. Visibility: Designed for clear visibility of the work area and load. 4.1.3.9 Base or Chassis: The base or chassis provides the support and stability for the crane. It can be fixed or mobile, depending on the crane type. Types: Fixed Base: Found in tower cranes, providing a stable foundation. Mobile Chassis: Includes wheels or tracks for movement, as seen in mobile and crawler cranes. 4.1.3.10 Electrical and Hydraulic Systems: These systems power various crane components and functions, including lifting, rotating, and extending the boom. Components: Hydraulic Pump: Provides power for hydraulic systems. Electrical Motors: Drive the crane’s movement and lifting functions. The key components and features of cranes are designed to work together to lift, lower, and move heavy loads efficiently and safely.
