hammer head tower crane

The boom section usually has 4m, 5m or 10m sections. Taking the 50m lifting boom as an example, its maximum unit mass is only about 1/5 of the total amount of lifting boom. Compared with the whole lifting, the lifting equipment required by the disassembling and assembling of the boom in air section by section is greatly reduced, which not only saves the cost of disassembling and assembling, but also is safer and faster.

The effective height of the hook is greatly improved, and the space utilization rate is high, so it is very suitable for the occasions with special requirements on height, such as the reconstruction and expansion of the airport, the construction beside the airport, the construction inside the tunnel and the factory building, and the construction under the high-pressure line, etc.

has the advantages of less total installation time, lower requirements for installation equipment, reduction of the weight of each tower crane and the use of smaller tower section and chassis.

When installing the lifting arm of an ordinary tower crane, the boom and tie rod must be connected on the ground before overall hoisting. At this time, the requirements for lifting equipment are the highest, with great lifting weight and lifting height

Topkit tower crane is generally used in the construction site or the bridge site, through the big arm slewing and the trolley far and near to control the position of the hook, can lift the object in the turning radius. Compared with tower crane with tower head and tie rod, the model of hoisting arm force is simple and clear. Because there is no tower head, the installation height is low, which makes the installation faster and safer. Suitable for large buildings
