Transmission form of electric top-running overhead crane and trolley transfer mechanism

The most common crane used in the workshop – the крана с верхним ходом is the most common type of crane used in the workshop. Equipped with CD and MD hoists, they are light and small cranes. The lifting capacity range is generally between 1-16t and the span is between 6-25 meters. For larger tonnage lifting capacity and span, it is best to choose an electric double-girder crane. The use environment is controlled within the range of -30-+40℃.

There are two modes of operation: ground operation and air operation. Generally, it is ground operation, and the operation is carried out manually and remotely. Sevencrane top running crane for sale are general-purpose cranes installed in machinery manufacturing, small production lines, warehouses, and manufacturing sites. Features are as follows:

The running motors used include single-speed conical squirrel cage motors (for running speeds of 30 m/min and 45 m/min) and conical winding motors (for running speeds of 75 m/min). Depending on the control mode, there are two electrical control modes. The electric hoist and the entire crane are equipped with safety devices, such as lifting limit switches, end limit switches, etc. This product adopts the form of separate driving. Driving and braking are accomplished by a conical brake motor. The transmission adopts a “one open and one closed” gear transmission. The closed gear part uses a 5-ton custom top running crane price conical hoist to reduce the speed of the trolley. machine.

There are two types of running motors used in electrical equipment: single-speed conical squirrel cage motors (for running speeds of 30 m/min and 45 m/min) and conical winding motors (for running speeds of 75 m/min). Depending on the control mode, there are two electrical control modes. The electric hoist and the custom top running crane price are equipped with safety devices, such as lifting limit switches, end limit switches, etc.

The bridge crane is a trolley moving mechanism, and the bridge crane generally consists of a bridge frame (also called a cart). It is composed of lifting mechanism, trolley and trolley transfer mechanism, control room, trolley conductive device (auxiliary slide wire), crane main power conductive device (main slide wire) and other parts.
Тележка размещается на направляющей моста и может перемещаться по ширине цеха. Тележка в основном изготавливается из сварных стальных пластин и состоит из рамы тележки, механизма перемещения тележки и механизма подъема на ней.
