Brief Description of the Order

Our customer - RASHMI GROUP is a steel company. Its products and services range from DI Pipes, TMT Bars, Pig Iron, Wire Rods, MS Billets, Sponge Iron, Sinter, Ferro Alloys, Pellet Plant and Cement to Laptops, Netbooks, All-In-One PCs and also Dredging.
The customer finally purchased 8 sets of QZ type grab bucket double girder eot crane and 1 set QD type double girder overhead crane with hook. The grab overhead crane is used for grabbing iron ore fines concentrate and grab bridge crane. Selection needs to be determined by material density and volume. QD type overhead crane with hook is used for equipment maintenance in steel mills. The customer's initial inquiry included specific parameters such as the operating speed and working level of the bridge crane, so the crane model was selected straightforwardly.

If you are unable to determine the specific parameters and types of bridge cranes you need, you can contact us at any time, and we can help you analyze and provide the most suitable crane according to your working conditions.

Comparison of QD and QZ double girder bridge cranes

QZ type grab bucket bridge crane and QD type overhead crane with hook are both double girder bridge cranes, both of which are more stable in operation than single girder cranes. The hoisting mechanism runs left and right on the track above the two main beams.

QD Overhead Crane with Hook

Lifting capacity：5-550 ton
Span length：10.5~35.5m
Working class: A4~A7
Ambient Temperature: -20~40℃

1. There are three operating modes of QD overhead electric winch crane:
Handle: people follow the car, saving personnel, not only can control the driving, but also hang objects. Disadvantages: It is more dangerous for people to walk with hanging objects
Remote control: It is not necessary to follow the traffic when lifting larger and more dangerous items. Disadvantage: limited field of view.
Air operation: the operation has a wide field of vision. Disadvantages: It is operated by special personnel and requires the cooperation of the following personnel.

2. The crane equipped with hooks is suitable for lifting work in machining, assembly workshops, metal structure workshops, metallurgy and foundry workshops and various warehouses.

3.Advantages: high working level, stability, low failure rate, speed parameters can be changed and designed according to user requirements.

QZ Grab Bucket Bridge Crane

Lifting capacity: 5~25 ton
Span length：10.5~34.5m
Working class: A6
Ambient Temperature: -20~40℃

1. QZ grab bridge crane is composed of a box bridge, a cart operating mechanism, a trolley, a grab bucket, and an electrical equipment. The structure is simple and the work is reliable. All the mechanisms of this machine are operated in the control room, and the directions for entering the platform door of the driver's cab are: end entry, side entry and top entry.

2. The crane equipped with grab bucket is suitable for power plant, freight yard, workshop, wharf, chemical industry, or open-air working environment for loading, unloading and transportation of ore, limestone, mineral powder, coke, coal sand and other bulk materials. The grab bridge crane can be used indoors or outdoors, and a rain cover device is added for outdoor use.

3.Advantages: Cab controls can be customized to your requirements for different job levels. Grab cranes can meet frequent heavy-duty use. Our grab cranes are equipped with two-speed mechanism for better working performance in terms of precision

Why Choose Yuantai Bridge Crane？

new design concept
Yuantai breaks the design concept of the crane hoisting mechanism and applies the planetary gear reducer to the hoisting mechanism. The hoisting mechanism adopts a direct link, which combines the motor, the reducer and the brake. It effectively improves the transmission efficiency, minimizes various transmission parts required by the hoisting mechanism, and reduces noise. At the same time, the mechanism has obtained an intellectual property patent.

Whole machine frequency conversion control
For all kinds of European standard single and double beam cranes, our company adopts ABB inverters for the whole vehicle. The inverters are 0-speed brakes to reduce the mechanical impact on the motor, reducer and structural parts. At the same time, automatic and intelligent cranes can be extended to realize unmanned remote monitoring and anti-sway function.

Low noise and maintenance free
(Reduce maintenance time and low maintenance cost) (Because of the simple structure, there are few types of accessories, which is convenient for later procurement, and also reduces the
stock). Our company's European standard cranes can effectively reduce the power consumption by 20%-30%, reduce the use cost and improve the use efficiency through the speed regulation of the frequency converter.

How to Choose the Right Crane?

First, determine the type of crane according to the site of use: cranes can be basically divided into gantry cranes and bridge cranes. Under normal circumstances, gantry cranes are mostly used outdoors, and bridge cranes are mostly used indoors with walls as supports.
Next, determine the crane model and tonnage: each type of crane is divided into different models according to the lifting tonnage, function, and heavy objects. Such as electric hoist bridge crane, double girder grab bridge crane, metallurgical crane, etc.
In addition, it is necessary to determine the tonnage of goods that the crane purchased by yourself will lift. The tonnage cannot be too small, otherwise the crane is easy to be overloaded, and if it is too large, it is easy to increase the procurement cost of the crane.
The key point is to determine the parameters of the crane. The main parameters are: the span of the crane is the distance between the two outriggers; the lifting height of the crane is how high the heavy objects need to be lifted; the lifting capacity of the crane; There are three types: operation room operation and ground operation, remote control operation, etc.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：

Improve efficiency: Cranes can use automatic controls, and special accessories to improve efficiency.
Break space constraints: In limited spaces, standard cranes may not fit due to their size. Custom cranes can be designed as compact or lightweight cranes.
Cost savings: Customized cranes can lead to long-term cost savings. Customized crane solutions ensure crane's performance is all necessary for your business.
