The following is the payment content
Within 30 days after acceptance, the unit shall apply for the registration certificate of the lifting machinery; the registration sign is placed or attached to the significant position of the device.
6. Duota homework
Multi -tower operation map
1. When there are multiple tower crane operations at the construction site, safety measures should be organized and implemented to prevent tower cranes from colliding with each other.
2. Metaida during the operation: 1). The minimum standing distance between the two tower cranes should be guaranteed to be at least 2m from the end of the arm of the tower crane and the tower body of the other tower crane; 2). 2).). The vertical distance between the components at the minimum position of the high -level tower crane and the low tower crane is not less than 2m.
