1. Overhead Traveling Crane Introduction

Overhead traveling crane is a lifting equipment that is horizontally mounted over workshops, warehouses, and material yards for material lifting. Due to its two ends located on tall cement columns or metal supports, resembling a bridge, it is called an overhead traveling crane.
The bridge of the overhead traveling crane runs longitudinally along the rails laid on both sides of the elevated structure, making full use of the space under the bridge to lift materials without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

 
Kingda crane has served industrial community by providing high-quality crane and service with more than 4,500 employees, 1.62 million M3 workshop and 3500 sets intelligent manufacturing facility. Our product covers electric hoist, overhead crane, gantry crane, grab crane, casting/ladle crane, electromagnet crane, anti-explosion crane, cleaning room crane and their spare parts.
Here, we will have a detailed introduction to the kinds of Kingda overhead traveling crane.

2.8 Grab Overhead Traveling Crane

Grab overhead traveling crane consists of box-weld bridge, grab trolley, long traveling mechanism, driver cabin and electric control system. The retrieval device is grab. Grab trolley is equipped with lifting and closing mechanism, and the grab is separately winded in the lifting and open-close drum by 4 wire rope. The open-close mechanism drives the grab to close and grab  material; When the grab outlet is closed, the lifting mechanism is started immediately, make 4 wire rope having same stress and carrying out lifting action. Only open-close mechanism is under working, along gran outlet is open, the material is poured out. Except the lifting mechanism is different, the others is the same compared with hook overhead traveling crane.
