A large load is constantly applied to this bridge.
Please report the results of the load test.
This pillar supports the load of the entire building.
This material can withstand a high load.
It's necessary to calculate the structure's load before design.
重量 refers to the actual weight of an object, while 荷重 refers to the force or load exerted on a structure or support, which may exceed simple weight (e.g. dynamic forces).
加重 (same reading as 荷重) means 'weighted' or 'aggravated' (as in 加重平均, weighted average), an unrelated concept easily confused with 荷重's meaning of a physical load.
過重 (also read かじゅう) means 'excessive' or 'overburdened' (as in 過重労働, excessive workload), whereas 荷重 is the neutral engineering term for a load or force.
Written the same as 荷重（におも）but read かじゅう, this is the technical engineering term for a load or force applied to a structure, while におも is the more general word for a heavy load or burden.
Compound of 荷 (か, 'cargo, burden') and 重 (じゅう, 'weight, heavy'). The reading じゅう is the on'yomi of 重, forming a Sino-Japanese technical term.
