Analysis from the Functional Technical Angle: Which Parts and the Features of Tower Suspension
The tower crane plays an important role in the "transportation center" in the construction, transportation and other industries with its huge lift. To know more about tower crane technology is very important for the majority of tower crane practitioners. Below, from the functional technical point of view analysis: tower crane from which several parts, the characteristics of each part.
From a functional point of view, the tower crane can be divided into seven parts: metal structure, parts, working mechanism, electrical equipment, hydraulic system, safety device and attachment Anchorage.
The tower hanging metal structure consists of a lifting arm, a tower body, a turntable, a bearing seat, a balance arm, a bottom frame, and a spire.
Tower lifting parts are made up of wire rope(the main force component of lifting), variable amplitude car(car frame structure, wire rope, pulley, wheel, guide wheel, wire rope support wheel, wire rope anti-roll, car traction tensioner and broken rope insurance, etc.), pulley , rotary support, hook and brake composition.

There are five kinds of Tower lifting work institutions: lifting mechanism, amplitude shifting mechanism, car traction mechanism, rotary mechanism and large car walking mechanism(walking tower crane.
Tower electrical equipment includes hydraulic pumps, hydraulic cylinders, control elements, tubing and pipe joints, fuel tanks and hydraulic oil filters and other major components.
Tower crane safety system and attachment Anchorage is limited to the switch(limiter), overload insurance overload power outage device, Buffer stop device, wire rope anti-release device; Anemometer, emergency safety switch, safety protection sound signal.

In general, in the process of building a building, the self-lifting tower can be used to set up two anchors to fix the ink.
The choice of attachment points on the building should be noted: the distance between the two attachment points is appropriate The fixed point should be set at the corner of the T-wall and the outer wall

For the frame structure, the attachment point should be laid at the root near the column; Arrange near the floor for power transfer and installation.

How to test the lifting weight limiter of tower
There is engaged in tower crane design, production of professional manufacturers, rich technical experience. The experiment of lifting weight limiter of tower is discussed below. The test of lifting the weight limiter in the tower is carried out according to the procedure. Each item is repeated three times, and each time it can meet the requirements.

1. Maximum rated weight test
Normal lifting maximum rated lifting Qm, starting weight limiter should not move, allow lifting.
The load lands and rises at the slowest speed after loading to 110 % Qm. The starting weight limiter should act to cut off the power supply of all lift-up loops. The load can not rise and output alarm signals.
2. Speed limit test:
For the lifting mechanism with multiple gears and different weights, each gear should be tested separately. The method is the same as 1. The test load is calculated according to the maximum weight allowed in the gear position.

Tell me about the height of the tower, Heqi.
There has mastered the advanced technology of the tower crane industry, which can ensure reliable quality and safety. Here, what is the height of the tower and the lifting height of the tower:
1. Tower hanging range
The horizontal distance between the center line of the tower swing and the center line of the hook, usually referred to as the radius of rotation or working radius. The angle between pitch and horizontal angle is specified in the manual for the lifting arm of the movable arm variation.

The range of movable arm variation is small, and the weight arm of horizontal arm type is always horizontal, and the range of variable amplitude is large. Therefore, the tower crane with variable amplitude of the car has an advantage in the working range.
2. Tower lifting height

The lifting height also becomes the effective height of the hook, which is the vertical distance from the base surface of the tower crane(or the top surface of the walking track) to the hook support surface. In order to prevent the lifting height of the tower crane from damaging the equipment, a height limiter is installed on each tower crane.
