Point / rigging point 吊點
A single place in the roof structure from which a load is hung, and the whole assembly that gets it there: the steel, the shackle, the hoist and the beam or beam clamp it lands on. A tour asks a venue for a point count and a weight per point; the venue answers with what its structure can actually take, which is rarely the same number.
中文
屋頂結構上用來吊掛負載的單一位置，以及到達該位置的整組配件：鋼索、卸扣、電動葫蘆與所承接的鋼樑或樑夾。巡演會向場館提出吊點數量與每點載重，場館回覆結構實際能承受的數字，兩者往往不同。

Easy to get wrong
"Point" can also mean a spot line or point hoist - a moveable single line, not a fixed structural attachment. Ask which a venue means before planning a load.
