Overview

This page covers a number of topics in crane safety, crane assembly, and crane maintenance. The topics are arranged in a loose chronological order. This sequence is apparent in the links above and the text below and is in a Before, During, and After order. Before deals with crane installation and setup. During is the usage cautions (DOs and DON'Ts. Last is the inspection checklist. For your convenience, the inspection checklist and usage cautions have been grouped in this document Form 504 (Short List for Safe Use) (PDF)

Crane Installation and Assembly

When setting up the crane, the legs should not be skewed. Legs should be positioned at 90° angles from the beam, as shown in the "from the ceiling" views below:

An exception to the last top-down view is when the crane is on an uneven surface. You may want a different leg height from end to end, but the beam should be level to prevent unwanted hoist travel.

Lifting Equipment and Rigging

A vital part of the lifting process is to be sure that all equipment has been inspected and is in good operating condition. For safe crane operation, the weakest link of the chain is a real consideration. As such, each piece of lift equipment (slings, lifting chains, hooks, lifting bars, and similar components must be inspected.) These inspection procedures are detailed in the respective manufacturer's installation and use instructions as well as within the applicable ANSI and OSHA standards. Some of these standards are listed in the following paragraph.

In addition to the inspection of the crane and the lift equipment, you should also make sure the load is properly balanced. For example, when lifting pipes, you should make sure you have positioned the load so that it is centered in the sling and it does not slip. Too, whenever lifting, employees should keep clear of suspended loads about to be lifted. Additional precautions are spelled out in OSHA 29 C. F. R. 1929 Safety and Health Regulations and the rigging equipment manufacturer's recommendations. Other lifting standards that may apply are ANSI B30.16-1987 for Overhead Hoists (Underhung) and ANSI B30.11-1988 Monorails and Underhung Cranes.
