What core parameter information is required when consulting the double girder overhead crane

Double girder overhead crane is a kind of bridge crane that is widely used and common nowadays. There are many parameters of the crane. For customers, if they know the core parameters and need them, they can have a simple understanding of the bridge crane. They can go to the manufacturer for information details and customize the appropriate crane.

The performance parameters of double-beam bridge crane that need to be understood include: rated lifting capacity, lifting height, service span, working speed and working level.

1. Rated lifting capacity: refers to the total weight of goods that can be lifted by the bridge crane within the normal working range, also known as the maximum lifting capacity.

2. Lifting height: the distance between the upper limit position and the lower limit position of the lifting appliance (hook, clamp, electromagnetic chuck, etc.).

3. Service span: the horizontal distance between the center lines of the two running rails of the crane.

4. Working speed (hoist lifting speed and trolley running speed)

(1) Lifting speed: refers to the lifting speed of the lifting hoist at the rated speed and when the lifting device is fully loaded.

(2) Crane running speed: refers to the crane running speed when the crane running mechanism motor is at the rated speed.

(3) Trolley running speed: refers to the running speed of the lifting trolley when the trolley running mechanism motor is at the rated speed.

5. Working level: refers to the full load of the crane lifting load and the busy degree of the number of lifting operations per unit time. Based on the comprehensive consideration of the developed reference standards, the working level of the crane is divided into eight levels, namely, A1-A8, light (A1-A3), medium (A4, A5), heavy (A6, A7) and extra-heavy (A8).

After recognizing the above parameters, users can have a better understanding of the equipment when purchasing the crane, and can accurately put forward their own needs when consulting with the crane manufacturer. Due to different engineering projects and different work nature, some users have their own core demands for the parameters of overhead crane; In this case, the formal crane manufacturer will provide customized solutions according to the customer's core requirements and design standards.
