  • 2018/5/23 · The most commonly-seen crane overloading scenarios are: Hoisting a load that is too heavy for the crane’s capacity Dragging a load Swinging a load Dropping a load suddenly Utilizing defective crane components Side-loading a boom The Human Error …

  • Overloading and Falling Materials in Crane Safety

    When a crane is overloaded, it is subject to structural stresses that may cause irreversible damage. Swinging or sudden dropping of the load, using defective components, hoisting a load beyond capacity, dragging a load and side-loading a boom can all cause overloading.”.

  • The overloading of the crane’s operational capacity is caused by some of the following: The presence of swinging or a sudden dropping of any load. Any defective components. The hoisting of a load that is beyond its normal capacity. The dragging of a load.

  • Other issues like dragging or pushing are a major concern because crane operators are usually focused on the load and not the crane’s structure moving overhead. Structural impact is another concern, which often occurs when operators have low visibility or aren’t able to control the load and maintain the relative position of nearby structures that could potentially impact the crane.

  • Once these occur, crane operators and nearby personnel can be injured by falling or failing parts. Overloading may occur in several different ways: Handling a load heavier than the crane’s capacity Swinging, dragging, or suddenly dropping a load Side-loading a

  • 7. Do not side load a crane by dragging a load or picking off the side. Make vertical lifts only. 8. Do not let the load strike the boom or outriggers. 9. Avoid hitting nearby structures with boom; if this happens the boom must be inspected prior to continued use. 10.

    2017/3/2 · Never walk under a lift, whether stationary or moving. Improper securing of the load is one of the leading causes of dropping loads with overhead hoists and cranes. If the load is insecure or off balance during a lift it may tip and drop. Training and experience with …

  • An overhead crane that permits positioning of the hoist directly over the load, regardless of the location of load within a crane bay, would be welcomed by users of overhead cranes. In one embodiment, the invention provides an overhead crane adapted to be supported by first and second main support beams that are spaced apart and generally parallel.

  • If we go back a few decades, crane operators only had load charts to depend upon when it came to determining the load capacity of their equipment. Moreover, critical measurements, such as the boom length, radius, angle, and wind speed, also had to be computed manually to arrive at a weight figure that was somewhat reliable.
