Subject: permanent reference mark gen. Здравствуйте.Перевожу программу проверки мостового крана. After bridge assembly is complete, measure and adjust bridge bumpers, proximity switch brackets and tow hook assemblies to carriage runway centerline. Using a laser tracking measurement system, or equivalent measurement method, establish the bridge rail center datum point at each suspension column on the top column surface closest to the bridge wheels. Paint a permanent reference mark in this location to be used for future measurements. Сложности с последним предложением. а также tow hook assemblies и bridge rail center datum point. Спасибо. |
