Introduction
This section GB/T 24810 raised crane design requirements, and gives design guidelines and now reflect crane design
Shaped design criteria. The practice has proved that the design guidelines to ensure the life of the crane to meet the basic safety requirements and crane components
Requirements are good. Failure to follow these design guidelines will result in increased risk of life or crane lowered. But the industry consensus.
New technology, new materials can also achieve the same effect or enhance safety and extend the life of the crane as a new solution.

3 Terms and Definitions
Terms and definitions GB/T 24810.1 established applicable to this section.
4 Lifting capacity limiter and indicator
4.1 General Requirements jib crane
Nominal weight of 1t or more cranes and overturning moment due to the load is greater than the 40000N · m shall be equipped with a scale
Given from the weight limiter and indicator.
Note. The wire rope hoists or chain hoists Lifting capacity does not change with the position of the load changes, do not install the rated capacity indicator.
4.2 rated capacity limiter parameters and performance requirements
4.2.1 Lifting capacity limiter shall comply with GB/T 24810.1-2009 4.3 requirements, according to GB/T 24810.1-2009
4.3.2 Requirements Operation.
4.2.2 rated capacity limiter should be enabled by a sustained action until the overload is removed, the lever back in place.
4.2.3 during the operation requires a rated capacity limiter means cooperating to prevent the load from the dynamic changes. Rated
Weight limiter shall permit the rated load and lifting device designed to accelerate the upward movement of the average acceleration.
Note. In general, the rated load test, adjustable limiter and set the appropriate value. For the series production of hoisting winch, adjustments during plant trial
Given from the weight limiter, full attention should be on the set value modification for future real boom time.
4.2.4 rated capacity limiter limits QL should satisfy the formula (1).
