Estructura del equipo de un puente grúa de 30 toneladas

A 30-ton bridge crane typically consists of several key components and structures. Here is a breakdown of the equipment structure commonly found in a bridge crane of this capacity:

Bridge Girder: The bridge girder is the main horizontal beam that spans the width of the crane bay. It supports the entire weight of the crane and the load being lifted. The bridge girder is usually made of steel and is designed to provide strength and stability.

End Trucks: The end trucks are located at each end of the bridge girder and house the wheels on which the crane travels along the runway rails. They support the bridge girder and provide a means for the crane to move horizontally.

Runway Rails: The runway rails are mounted on the elevated structure or building columns and provide a fixed path for the crane to travel along. The end trucks’ wheels roll on these rails, allowing the crane to move horizontally along the length of the crane bay.

Hoist and Trolley: The hoist and trolley assembly is responsible for lifting and moving the load. It consists of a hoist unit that contains the motor, drum, and lifting mechanism. The hoist is mounted on a trolley that runs along the bridge girder, allowing the load to be moved horizontally.

Festooning System: The festooning system includes cables or hoses that provide power, control signals, and other utilities to the moving parts of the crane, such as the hoist and trolley. The festooning system is designed to accommodate the movement of the crane without causing excessive stress or strain on the cables.

Controls and Operator Cabin: The controls for operating the crane are typically located in an operator cabin or control panel. The operator can use the controls to move the crane, operate the hoist and trolley, and perform other necessary functions. The operator cabin provides a safe and comfortable working environment for the crane operator.

Safety Features: A 30-ton bridge crane will include various safety features to ensure safe operation. These may include limit switches to prevent overtravel, emergency stop buttons, overload protection devices, and safety interlocks.

It’s important to note that the specific equipment structure of a 30-ton bridge crane can vary depending on the manufacturer, design, and application requirements. The above components outline the general structure commonly found in such cranes, but there may be additional features or variations based on specific needs.
