Inner climbing tower crane QTGNP Series
We successfully developed this new kind of crane which is used inside buildings. It can greatly save your cost by saving mast sections.
Product Description
1\Fix two pieces of ready-made girder steel to concrete beam of building's core tube by sixteen bolts, then install strengthen attached frame on the girder steel and adjust the gap between guide pulley and tower body(generally two to five millimeters). Note: The armoured concrete beam of building must be designed by designing institute and up to the requirement of bearing capacity.
2\Fix the jib in the direction of vertical to climbing crossbeam and adjust the range of trolley to make the barycenter of tower crane pass jacking oil cylinder.
3\Put the claw hand of inner climbing jacking crossbeam on inner climbing pathway, raise the tower body up, and put claw hand of inner climbing base section on vertical position. Figure (1); Put the claw hand of inner climbing base section level, limiting tower body sliding down, draw back jacking oil cylinder. Figure (2); After jacking oil cylinder is drawn back, put the claw hand of inner climbing jacking beam level, and put the claw hand of inner climbing base section vertical. Figure (3); Repeat it again and again to make tower body rise as desired requirement. Figure (4). When tower crane rises to desired height, lay two load bearing support square beams under the channel steel of inner climbing base section, let them bear the weight of tower crane.
