The following is a simplified set of steps for calculating electrical enclosure temperature rise: First, find the input power, expressed in watts per square foot. Divide the amount of heat dissipated within the enclosure (in watts) by the enclosure's surface area (in square feet).

Many electrical and boom electronic components protected by boom electronic enclosures generate heat when current flows through them. Component types that often generate heat include:

The jib crane is a light duty crane and is a practical light work station lifting equipment. It has the characteristics of high efficiency, energy saving, trouble-saving, small footprint, easy operation and maintenance. It is especially suitable for short distance, frequent use and intensive lifting operations. It is mainly composed of a column, a rotating arm, a support arm and a reducer, an electric chain hoist, and electrical parts.

The emergence of cantilever cranes has reduced the intensity of human labor, has large lifting capacity, large lifting height, and long service life. The advantages of the cantilever crane are: low friction, light walking, and small structural size, which is beneficial to improving the verticality of the hook. It has a reasonable structure and is custom-made with high-quality materials. It is strong and durable. It has received very good feedback from users in the market. It has strong site adaptability and can still operate smoothly in dense and spaced working sites.

How to choose a cantilever crane needs to be decided based on many factors, such as material selection, handling weight selection, drive type whether it is electric, pneumatic or manual, and floor area selection.

Cantilever cranes include curved jib jib cranes, fixed column jib cranes, mobile jib cranes, and double-arm jib cranes. Although they have different names, they also share common characteristics. For example, it occupies a small area, has high work efficiency, and has relatively high reliability during use. It is very suitable for short-distance lifting and transportation, has high frequency of use and can carry out relatively intensive lifting work.
