The most common crane used in the workshop - the electric overhead traveling crane 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℃.

The trolley operating mechanism of the overhead traveling bridge crane is the transport mechanism of the entire crane, including the motor, controller, coupling, transmission shaft, reducer, angular bearing box and trolley wheels, etc.

1. During lifting operations, it is necessary to have a comprehensive understanding of the working environment, travel routes, buildings, and object weights at the work site. 2. Operators should sound the signal before carrying out lifting, turning, luffing, walking, hook lifting and other actions, and strictly implement the commander's signal. Special operators must have a special operation safety operation certificate.

桥式起重机的运输、安装、调试和维护费用通常会占到总成本的一部分，但具体所占比例会受到多种因素的影响，包括起重机的类型、尺寸、设计要求、安装位置和运行环境等。

In a specific project, the following factors may affect the proportion of overhead crane transportation, installation, commissioning and maintenance costs:

Single-girder cranes usually refer to single-girder bridge cranes. The main girders of electric overhead traveling crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. Lifting trolleys are often assembled with chain hoists, electric hoists or hoists as lifting mechanism components.
