256HC Mast SectionOther than the tower crane, what about the vertical transport?
we all know that tower crane has been widely used in construction and has become an indispensable construction machinery in construction installation and construction. In addition to the tower crane, there is no vertical transport machinery, the following for you to answer.

1. Gantry, headframe material hoist, Gantry, headframe are used for vertical transport of materials in construction. Gantry, headframe is named for the frame structure of the shape. The Gantry is made up of a beam and two columns, and is shaped like a door frame. The Derrick is made up of four-sided rods, and is shaped like a cross-section frame. The safety protection devices of the material lifter of Gantry and headframe are: Stop Device, rope breaking protection device, hanging basket safety door, floor entrance stop railing, upper material entrance protective shed, super height limit device, lower limit device, overload limit device and communication device. The installation and dismantling of the Gantry and headframe material hoists must draw up special construction schemes. And shall be carried out by a qualified team. 2. External Elevator, building construction external elevator also known as the wall-type Elevator, is a vertical Derrick (column) rail-type External Cage Elevator. Mainly used in the construction of industrial and civil high-rise buildings, bridges, mines, water towers of high-rise materials and personnel of the vertical transport. The structure principle of the lift is that between the carrier cage and the balance weight, it is suspended by wire rope on the fixed pulley at the top of the column, which is rigidly connected to the building structure. The cage is electrically driven and moves vertically along the column Guide Rail by means of the reaction on which the rack is fixed on the column. Because of the firm structure and convenient disassembly and assembly, the external elevator does not need another machine room, and is widely used. The columns are made into standard sections of a certain length, each section can be interchanged, and assembled on the construction site according to the required height. The general erection height can reach 100m, and it can reach 200m when used in super high-rise building construction. The elevator can be assembled with the help of the electric hanger which is installed on the top of the elevator, and the lifting equipment such as the tower crane can be assembled on the construction site. In addition, the symmetrical layout of ladder cage and balance weight makes the overturning moment very small, and the column is firmly connected with the building structure through the attached wall frame (without cable) , so the force is reasonable and reliable. To ensure the safety of use, the external elevator itself is equipped with the necessary safety devices, which should always be in good condition to prevent accidents.
