What is the allowable deviation above the wall of 50 10 tower crane?
Your problem should be that the attachment section set at 40M from the ground is crooked, and the upper attachment spacing should not exceed 40 m. Your problem is the installation of the tower crane and the quality of the tower crane itself. It is 3cm below and 5cm above, and the actual deviation is 20 mm. The swing of the tower crane under load lifting and wind load has exceeded 20 mm, so there will be no problem. Follow-up: the key problem is that the up-and-down contrast forms a retreat angle. Will the crane's rotating boom be distorted under load, causing the tower crane to collapse? Thank you for your supplement: 1. The installation of tower crane must be specially accepted by a qualified testing organization, and this problem should be paid attention to during the acceptance. 2. Measure the verticality of tower crane when lifting. 3, 40M from the ground should be attached to the wall, the above paragraphs in no more than 24M attached to the wall.
