Safety Bulletin

Hoists, Cranes and other Lifting and material-movement related equipment USERS, must be knowledgeable about the safe and proper use of this equipment and be aware of their responsibilities as outlined in all applicable standards and regulations.

The ASME/ANSI B30 Standard contains provisions that apply to the construction, installation, operation, inspection, testing, maintenance, and use of cranes and other lifting and material-movement related equipment.

As OSHA's, ASME and ANSI standards state, the installation, setup and operation of these units and equipment shall be performed by a qualified person.

OSHA requires rated load tests for new and altered cranes, OSHA's standard at 29 CFR 1910.179(k) states:

  1. Operational tests.
    1. Prior to initial use all new and altered cranes shall be tested to insure compliance with this section including the following functions:
      1. Hoisting and lowering.
      2. Trolley travel.
      3. Bridge travel.
      4. Limit switches, locking and safety devices.
    2. 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.
  2. Rated load test. Test loads shall not be more than 125 percent of the rated load unless otherwise recommended by the manufacturer.

Once a rated load test is performed, paragraph 1910.179(k)(2) requires that "[t]he test reports shall be placed on file where readily available to appointed personnel."

In order to ensure Safety and installation requirements Prowinch requires Load Tests to be performed prior to initial use for all Hoists, Winches and Cranes, as well as other related components. Not fulfilling this requirement is dangerous, could lead to equipment failure and will automatically void the warranty.

The B30 Standard is intended to:

(a) Prevent or minimize injury to workers, and otherwise provide for the protection of life, limb, and property by prescribing safety requirements.

(b) Provide direction to manufacturers, owners, employers, users, and others concerned with, or responsible for, its application.

(c) Guide governments and other regulatory bodies in the development, promulgation, and enforcement of appropriate safety directives.

The equipment covered by the B30 Standard is subject to hazards that cannot be abated by mechanical means, but only by the exercise of intelligence, care, and common sense. It is therefore essential to have personnel involved in the use and operation of equipment who are competent, careful, physically and mentally qualified, and trained in the proper operation of the equipment and the handling of loads. Serious hazards include, but are not limited to, improper or inadequate maintenance, overloading, dropping or slipping of the load, obstructing the free passage of the load, and using equipment for a purpose for which it was not intended or designed.

DO NOT

  1. DO NOT Operate, install, or repair the hoist unless trained and authorized.
  2. DO NOT Operate the hoist unless you have first read the operator's manual.
  3. DO NOT Operate the hoist without appropriate PPE and without performing a pre-shift inspection.
  4. DO NOT Operate the hoist if not complying with all required OSHA regulations.
  5. DO NOT Lift more than the rated load.
  6. DO NOT Lift people or lift loads over people.
  7. DO NOT Wrap the hoisting rope or chain around the load.
  8. DO NOT Operate with the chain/rope not properly seated in the sprockets, drum, or sheave.
  9. DO NOT Operate unless the direction of the hook travel agrees with the direction shown on the control.
  10. DO NOT Operate the hoist unless the hook travel limit devices function properly. (Test without a load PRE-SHIFT )
  11. DO NOT Operate the hoist with twisted, kinked, damaged, dirty, or unlubricated chain or rope.
  12. DO NOT Operate a damaged or malfunctioning hoist.
  13. DO NOT Operate the hoist when the hook is not centered under the hoist
  14. DO NOT Remove or obscure this tag or other WARNING & SAFETY LABELS

DAILY CHECKLIST

TAGGED HOIST: Ensure the crane or hoist is not tagged out of order.

CONTROL DEVICES: Test Run. Ensure all motions agree with control device marking.

BRAKES: Check all motions for excessive drift and abnormal stopping distances.

HOOK: Check for damage, cracks, nicks, gouges, deformations on throat opening, wear on saddle or load-bearing point, and twist.

HOOK LATCH: Check for proper operations.

WIRE ROPE: Check for broken wires, broken strands, kinks, and deformation or damage to the rope structure.

CHAIN: Check for corrosion, wear, elongation, twist, nicks, or gouges. Keep Chain/Wire Rope Clean and Lubricated.

REEVING: Check the rope for proper reeving and that rope parts are not twisted.

LIMIT SWITCHES: Ensure that all limit devices stop lifting motion before the load block or chain/rope stop strikes the hoist.

OIL LEAKAGE: Check for any signs of oil leakage on the crane/hoist and the floor.

UNUSUAL SOUNDS: Check for unusual sounds from the hoist while operating.

WARNING & SAFETY LABELS: Ensure that labels are not missing and they are legible.
