1. There are utility trenches on the road, and steel covers need to be placed over them as vehicles will pass over them. How should the load capacity be determined in this case? 2. There is also an operation platform on the tower equipment, which is mainly used for operators to work on; how is the load lifted?
Are there any standard specifications to refer to?
There are standards for this; road ditch covers come in heavy and light versions. The maintenance platform must take into account the weight of the components that need to be maintained. @Zhizheming
Sir, could you tell me what the guidelines are?
The load capacity for pedestrian use on road ditch covers is 4000 N per square meter. The requirements for vehicle traffic should be determined by the transportation specialists. The load capacity for operation platforms is 2000 N per square meter, while that for general maintenance platforms is 4000 N per square meter. Specialized maintenance platforms require specifications to be provided by the equipment and transportation specialists.
The weight that can be lifted is equal to the maximum load capacity of the vehicle plus the vehicle’s own weight
I’m confused – what’s the issue here? For vehicles carrying goods, just check how many tons they weigh; it’s sufficient to use a higher safety factor. And for vehicles carrying one person, just consider it as if two people are on board.
For the platform, ordinary steel grating will suffice; for areas used by forklifts, it’s enough to use thicker flat steel bars；
