With the continuous development of mechanized production, when we transfer heavy objects, we will not use manpower now, but use cranes to finish. There are many types of equipment for selection, each type of equipment, its performance is not the same, the following port crane manufacturers take you to know.
1. Light lifting equipment
Electric hoist, hand chain hoist, chain electric hoist, emblem type hoist, etc., have light and compact structure, light weight, small volume and high versatility.
2. Bridge crane: it is widely used. It is erected on the track of fixed span pillars of buildings and used in workshops and warehouses. Do loading and unloading and lifting transfer work indoors or outdoors. In the factory, it is generally called crane.
