Crane operation and load testing

These protocols are a standard part of Konecrane’s maintenance and crane modernization programs.

OSHA 1910.179 Overhead & Gantry Cranes Regulations
The following excerpt is taken directly from OSHA 1910.179.*

Operational tests

• Prior to initial use all new and altered cranes shall be tested to insure compliance with this section including the following functions:
  • Hoisting and lowering
  • Trolley travel
  • Bridge travel
  • Limit switches, locking and safety devices
• The trip setting of hoist limit switches shall be determined by tests with an empty hook traveling in increasing speeds up to the maximum speed. The actuating mechanism of the limit switch shall be located so that it will trip the switch, under all conditions, in sufficient time to prevent contact of the hook or hook block with any part of the trolley.

Rated load test

Test loads shall not be more than 125 percent of the rated load unless otherwise recommended by the manufacturer. These test reports shall be placed on file where readily available to appointed personnel.
