7 Ton overhead crane&underslung crane Overview

A 7 ton overhead crane (underslung crane) is a type of crane that runs on the lower flange of the runway beam, which is usually suspended from the roof of the building. It is suitable for applications where the headroom is limited or the hook height is required to be maximized. An underslung crane can be single girder or double girder, depending on the lifting capacity and span. It can also be equipped with different lifting devices, such as an electric hoist, Wire Rope Hoist, or Chain Hoist.

South Africa Customer Crane Needs|Plastic Industry Crane

The customer is a plastic industry company in South Africa, which produces various plastic products, such as bottles, containers, pipes, etc. The customer needed a crane to lift and transport the plastic materials and finished products in their workshop. The customer had a low ceiling height and a large span in their workshop, so they needed a crane that could make full use of the available space and have a high lifting height. The customer also wanted a crane that was reliable, safe, easy to operate, and low maintenance.

7 Ton Overhead Crane&Underslung Crane Solution

After understanding the customer’s needs and site conditions, we recommended a 7 ton overhead crane (underslung crane) with a span of 18 meters and a lifting height of 9 meters. The crane was equipped with an electric wire rope hoist with a lifting speed of 8 m/min and a travelling speed of 20 m/min. The crane was controlled by a wireless Remote Control, which was convenient and flexible for the operator.

The main features of the underhung crane were:

• The underslung design saved the headroom and increased the hook height.
• The single girder structure reduced the weight and cost of the crane.
• The electric wire rope hoist had a high lifting efficiency and durability.
• The wireless remote control had a long transmission distance and a high safety factor.
• The crane had a modular design and easy installation.
• The crane had a low noise level and environmental protection.
