Luffing mechanisms allow cranes to change the reach of their jibs in a vertical plane. There are two main types of luffing mechanisms: wire rope luffing and hydraulic luffing. Wire rope luffing uses wires to raise and lower the jib, while hydraulic luffing uses hydraulic cylinders. The document also discusses calculating the lifting capacity and power of cranes using luffing mechanisms. Formulas are provided for lifting force, power, average velocity, and average power.
This document discusses motive power sources and hoisting mechanisms for cranes.
It describes various motive power sources including electric, internal combustion, hydraulic, and manual drives. For manual drives, it discusses lever and wheel operations placed at ground level or elevated.
It also summarizes electrically-driven and manually-driven hoisting mechanisms. The electrically-driven mechanism typically uses an electric motor connected to a gear reducer and hoisting drum. The manually-driven mechanism uses gearing and levers or wheels to reduce effort and raise loads.
Mathematical equations are provided for calculating torque requirements, speed ratios, and other parameters for hoisting mechanism design and analysis.

1. Wire ropes are composed of individual wires that are subjected to various stresses when in use. A mathematical treatment of all the factors controlling the wires is impractical. Rope design codes are based on maximum tension factors and safety.
2. Lifting tackles are systems using stationary and movable pulleys interlinked by wire ropes to gain mechanical advantage in force or speed. The basic characteristic is the mechanical advantage which is the ratio between the load force and rope force.
3. Drums, pulleys, chains and their attachments are also discussed in detail regarding design, types, and safety factors for hoisting and haulage applications. Standards for selection of proper rope grade and mechanical components are highlighted.
This document discusses various load handling attachments used in cranes, including hooks, hook blocks, grabs, buckets, and lifting magnets. It describes their uses, classifications, materials, design requirements, and operating procedures. Hooks come in different styles like ordinary and ramshorn patterns, and are made of materials like low-carbon steel. Grabs are used to reduce loading time and increase productivity when handling unit loads. Buckets can be single-line or two-line and are used to lift and transport loose materials. Lifting magnets operate on direct current and are suitable for handling steel and cast iron loads. The document provides details on the specifications, calculations, and safety considerations for different load handling attachments.
This document discusses the classification and basic technical specifications of various lifting and conveying equipment. It begins by classifying lifting machines and mechanisms into categories such as hoists, cranes, conveyors, and elevators. It then lists examples of equipment that fall under each category. The document concludes by describing some common technical specifications of lifting equipment, such as load capacity, reach/span, torque, lifting height, and operational speeds. It also discusses utilization rates and performance metrics.
