Why are the prices of the same model Double Girder Cranes Different?
As a large-scale hoisting machinery, double-girder bridge cranes are generally customized to meet the required requirements. In addition to quality, price has become the most concerned aspect of crane users. However, there are many crane manufacturers in the market, and the types of products are even more dazzling. Take the double-girder bridge crane as an example, how does its price difference come from?

Brand affects price
Another factor that affects the price of double-girder bridge cranes is the brand. Generally, a well-known company may have a higher product price than other less-known companies.
Material performance affects price
25 ton double-girder bridge cranes are the same as other products. The price difference is mainly reflected in the material and performance. The material mainly refers to the materials used for each component of the equipment. Generally speaking, most of them are steel.
But anyone who knows something about the steel market knows that the current price of steel is also rising with the rise in prices.
The quality of accessories affects the price
As far as spare parts on double-girder cranes such as pulley blocks, wire ropes, lifting hooks, couplings, and crane wheel sets are concerned, there will be great differences in price depending on the type and material.
In addition, the performance of the crane mentioned includes many aspects, including the quality of the equipment, specific functions, functions, etc., which will be used as factors to measure the price of the equipment.
Installation and shipping affect price
Installation and transportation costs, the distance between the manufacturer and the customer's area, and transportation costs have a greater impact, which is also closely related to the installation cost.

Parameters that affect the price of double girder bridge cranes
The lifting weight refers to the maximum weight that the crane needs to lift heavy objects. Try to choose a crane that is slightly larger than the maximum weight to avoid damage to the machine caused by overloading. When making an inquiry, the manufacturer usually asks about the lifting capacity of the product and the weight of the item to be lifted. This has a big impact on the price of the crane.
Span refers to the distance of the load-bearing beam of the crane, which also has a considerable impact on the price of the equipment.
The hoisting height is mainly a matter of choosing the electric hoist, the higher the hoisting height, the more expensive the price will be.
Stroke refers to the running distance of the crane, which mainly affects the use length and installation cost of the track and power supply slide wire.
