Mechanical Systems Commissioning Description of lifting and moving devices

There are many types, variations and capacities of lifting and moving devices to move objects and personnel. The devices addressed in this course are primarily for moving objects; however, freight elevators as well as personnel elevators can be used for moving personnel and objects. Included in this course is a description of lifting and moving devises commonly encountered.

  1. Lifting devices. A description of typical cranes and other common lifting devices follows.
    1. Bridge cranes are versatile and used in many applications. They consist of columns, rails, a bridge, trolley, one or more hoists, and for control, a pendant, cab and radio operator.
    2. Jib cranes have a limited access area but are less expensive than other cranes. They consist of a column, swinging jib, trolley, hoist and pendant.
    3. Gantry cranes are like mobile bridge cranes. They consist of a mobile gantry, trolley, hoist and pendant.
    4. Frequently used non-powered lifting devices include hydraulic jacks, chain hoists, and rigging such as chains, wire ropes, slings, chokers, hooks and spreader bars.
  2. Elevators. Elevators consist of hydraulic ram lifts or motor driven cable lifts, a framed elevator shaft, an elevator car/enclosure with doors, telephone or intercom and push button controls.
  3. Lifting and moving devices. More information on requirements for design, maintenance, and testing of lifting and moving devices is to be found in the Occupational Health and Safety Administration, Standards (OSHA), Regulations Standards 29 CFR 1910 – Subpart N Material Handling and Storage, 1910.179 Overhead and gantry cranes, and 1910.184 Slings, plus 1926 – Subpart H Material Handling, Storage, Use, and Disposal, 1926.251 Rigging equipment for material handling, as well as 1926 – Subpart N Cranes and Derricks, 1926.550 Cranes, derricks, hoists, elevators, and conveyers, and 1926.552 Material hoists, personnel hoists, and elevators, and 1926.554 Overhead hoists. Additional information is supplied by the American Society of Mechanical Engineers (ASME) A 17.1 Safety Code for Elevators and Escalators.
