Inspection of Hoist Brakes – Overhead Crane Equipment

Many older style hoists use a friction type brake for the holding brake and a mechanical (Westin Style or other) brake for the controlled lowering. Newer style hoists often use the friction brake for both the holding and controlled lowering and provide a brake that is capable of 150% of full load hoisting torque.

Routine crane and hoist inspections are required to ensure continued safe crane and hoist operations of the crane and the safety of the employees around the crane. An initial inspection of the crane prior to initial use of new and altered cranes is necessary. Once placed into service, overhead cranes will require two different types of inspections.

Remote greasing systems may fall into disrepair, meaning it becomes necessary to grease the bearings locally, often involving the use of rigging to climb up a crane and gain access to the relevant

Answer: This depends on the type of crane. OSHA regulation 1910.179 applies to top-running overhead and gantry cranes with top-running trolley hoists. For these types of cranes, monthly inspections of the hoist’s chain, wire rope and hooks are required with a recorded certification.

Time Optimal Control of Overhead Cranes with Hoisting of the Load reduce the main problem of a double pendulum crane. From the performance comparison of the results, the proposed method has

Other standards that all overhead crane users should be familiar with include the ASME B30.2, ASME B30.11, ASME B30.16, and ASME B30.17. Also, read and be thoroughly familiar with your overhead crane user’s manual, and check local and State requirements to make sure you comply with all laws. Tests are an attempt at a controlled failure.

A chain hoist is used to lift or lower a load.It has an electrically powered motor with a drum of wheel that has a chain wrapped around it. The load is attached by a hook. This piece of equipment is the workhorse of many workshops.

For some overhead cranes with special functions, such as the overhead crane for quench, should has fast-down device, for overhead crane with high lifting height, it should improve lifting speed

But hazards do exist with all types of cranes—including overhead cranes—and in all facets of crane operation. (Overhead cranes are defined by OSHA 1910.179(a)(8) as a crane with a movable bridge carrying a movable or fixed hoisting mechanism, and traveling on an overhead fixed runway structure.)

However, items

OSHA requires rated load tests for new and altered cranes

All new overhead and gantry cranes constructed and installed on or after August 31, 1971, shall meet the design specifications of the American National Standard Safety Code for Overhead and Gantry Cranes, ANSI B30.2.0-1967, which is incorporated by reference as specified in Sec. 1910.6. (3) Modifications. Cranes may be modified and re-rated

A gantry crane is a type of overhead crane that is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on tires or on rails that are embedded in the floor or ground structure.

A load rigged with the crane hook 4 ft south of the center of gravity will initially swing ___ upon lift-off. a. Approximately 4 ft north

A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
