Main feature of  QD Type 150t and over 150t Overhead Crane with Hook

It adopts bias-rail and wide box double girder bridge, which has a large loading capacity and great stability.

It adopts car structure. It has a balance wheel load of wheel, which has a clear structural stress.

The traveling mechanism of the crane is installed inner the main girder, which adopts universal coupling torque.

The electronic components is installed inner the main girder, which can prevent the electronic components from influencing by bad working environment.

Bridge

Bridge is the main stress components of the overhead crane, which adopts double girders and double rails pattern. The main stress component contains main girder and end girder. Also the auxiliary stress component includes track of the trolley, walking board, handrail, ladder and other mental structure.

The main welding joint adopts gas shield welding or submerge arc welding. After it has be welded, it must be check the welding joint in line with GB/T 14405—2011 general-purpose overhead crane.

The materials of the main stress component adopts Q235B. The cross section of the main girder adopts ANSYS finite element calculation methods to calculate and analyse, which aims to ensure the the stress component having enough strength, rigidity and stability of whole overhead crane.

All of the steel plate should be experienced shot blasting, which can reach Sa2.5 standard

The deflection upwards should be0.91.4S/1000. Then, the position of max deflection upward should be controlled in the middle span of 1/10.

The end girder is box structure. The end girder and main girder is connected by rigid connection. The end girder is transported disassembly methods. It adopts high-strength bolt to connect. The junction plate adopts reaming bolt to fix position.

The main constitution of structure

The main structure contains trolley, lifting mechanism, traveling mechanism of trolley, traveling mechanism of crane

Hook group

The overhead crane is designed and manufactured strictly in according to GB/T 10051-2010 standard. The hook of the overhead crane is forged.

On the mouth of the hook is set with fastener, which is to prevent the handled materials from falling.

The specific value of the diameter of the pulley is 20 bigger than the diameter of the steel wire rope. All of the pulleys are set with protective cover or the device to prevent the steel wire rope from jumping from the concave-groove.

Wheel parts

The bearing support of the wheel parts adopts vertical angle-type structure. By means of bolt, the vertical angle box is fixed on the angle block of the trolley frame or the end girder of the gantry. The structure can adjust the wheel when it is used to maintain. It can avoid the rail gnawing which is caused by the lateral deviation and vertical deviation. The vertical angle box is a mature technology which is used widest at present.

The choosing of the diameter of the wheels and the materials depend on the max.loading capacity of the wheel and the most unfavorable condition. It aims to avoid the overloading of the wheel parts.

The material of the wheels adopts ZG340-640 and the it must experience advanced quenching by induction heat treating. The hardness should accord with:

The hardness of tread and inner side of rim  HB)            ≥300380

The min. depth of hardening zone         mm)              20

The min.hardness of depth of hardening zoneHB)            ≥260
