3 Terms and Definitions
Terms and definitions GB/T 24810.1 established applicable to this section.
4 Lifting capacity limiter
4.1 crane under the following conditions shall be fitted with the rated capacity limiter.
--- Danger of tipping;
--- Cranes may not be expected to carry the load, the load will result in overload institutions and structures.
4.2 rated capacity limiter should be allowed to lift the device with a rated load in order to design the average acceleration Rao accelerated upward movement. Typically, the amount
Given load test, the limiter should be adjusted and fixed at an appropriate value. For the series production of the crane during the plant trial, test
Into account when using the crane bridge deformation, it may be appropriate to set the rated capacity limiter.
4.3 should be dynamic load limiters preventing detection function is in use.
4.4 rated capacity limiter setpoint QL should satisfy the formula (1).
Where.
Rao --- design lifting average acceleration;
QL --- by the lifting of the flexible member (rope, chains, etc.) restricted nominal weight;
QGL --- total starting weight by lifting flexure quality, quality fixed spreader and rated (nominal weight = separable from the weight of the spreader Quality +
Effective from the weight) constituted;
2 --- GB/T 22437.1-2008 in 6.1.2.2.1 for performing amplification factor checking the crane capacity.
4.5 In special cases, bridge and gantry crane lifting capacity and load position in certain areas is restricted to less than the lifting mechanism
