Frequently Asked Questions (FAQs)

1. What are the key parameters to consider when selecting a rolling crane hoist in China?

When selecting a rolling crane hoist in China, several key parameters need to be considered. The lifting capacity is crucial, as it determines the maximum weight the hoist can handle in a single operation. This is usually measured in tons or kilograms. Another important factor is the lifting speed, which is the vertical displacement speed of the rated load, typically measured in meters per minute. The working class of the crane, which is determined by the frequency of use and the size of the load, also needs to be considered. Additionally, the voltage and frequency of the power supply, as well as the type of hoist (wire rope or chain), should be taken into account. The working environment, including temperature, humidity, and whether the crane will be used indoors or outdoors, is also essential for proper selection[2][4].

2. How do I determine the working class of a crane hoist?

The working class of a crane hoist is determined by two main factors: the frequency of use and the size of the load it bears. The frequency of use is known as the hoist utilization class, and it ranges from M1 to M8, with M1 being the least frequent and M8 being the most frequent. The load state refers to the size and weight of the loads the hoist will handle. To confirm the working class, you need to provide details about the working environment, working duration, and frequency of the crane. This information will help engineers calculate the appropriate working class for your specific needs[2][4].

3. Can rolling crane hoists be customized to fit specific workshop conditions?

Yes, rolling crane hoists can be customized to fit specific workshop conditions. Many Chinese manufacturers offer customization options based on the customer’s requirements. For instance, if you have low headroom in your workshop, special designs can be provided to accommodate this constraint. Customization can include different operation methods such as pendent controller, remote control, or cabin control, as well as adjustments to the beam model, power supply system, and hoist type. Providing clear information about your workshop dimensions and operational needs will help manufacturers design a hoist that best suits your demands[2][3].

4. What are the differences between single girder and double girder crane hoists?

Single girder and double girder crane hoists differ in several key aspects. Single girder cranes consist of a single bridge girder supported on two end trucks, with the trolley hoist mechanism running on the bottom flange of the bridge girder. These cranes are generally more economical and suitable for lighter lifting capacities, typically up to 20 tons. Double girder cranes, on the other hand, consist of two bridge girders supported on two end trucks, with the trolley running on rails on the top of the bridge girders. Double girder cranes offer higher lifting capacities, increased height, greater stability, and more versatility, making them suitable for heavier and more complex lifting tasks[4].

5. How are rolling crane hoists delivered and installed, especially for long or heavy components?

The delivery and installation of rolling crane hoists, especially for long or heavy components, require careful planning. For long main girders, the girder is often divided into different pieces, each within a manageable length (typically within 11.8 meters), to facilitate container shipping. Upon arrival, these pieces are connected using high-strength bolts. For installation, many manufacturers offer professional installation teams that can assist in setting up the crane at your site. Additionally, logistics and document departments can help arrange the shipment, and the hoists and electrical components are usually packed in fumigation wooden boxes to ensure safe transportation[2][3].
