A double girder overhead crane with hook is a type of heavy-duty crane that can lift and move loads up to 20 tons. It consists of two parallel girders that support a hoist and a hook. The hook can be used to attach various lifting devices, such as slings, chains, or magnets. The crane can travel along rails mounted on the ceiling or walls of a workshop, warehouse, or factory.
A double girder overhead crane with hook is ideal for applications that require high lifting capacity, long span, and high working class. It can handle complex and diverse tasks, such as loading and unloading materials, assembling and disassembling parts, or transferring goods between different locations.
One of our successful sales cases involved selling a 20 ton double girder overhead crane with hook to a German mining company. In this case study, we will show you how we identified the customer’s needs, offered them the best crane solution, and delivered the crane with high quality and efficiency.
Germany Customer Crane Needs|Mining Crane
The customer was a mining company based in Germany. They specialized in extracting and processing coal, iron ore, and other minerals. They had a large underground mine that required frequent lifting and transportation of heavy materials and equipment.
The customer contacted us through our website and expressed their interest in buying a double girder overhead crane with hook. They said they needed a crane that could lift to 20 tons of weight and span up to 25 meters. They also wanted a crane that could work in harsh environments, such as high temperatures, dust, and humidity.
We replied to the customer promptly and asked them some more questions about their specific requirements. We learned that they needed a crane that could operate safely and reliably in the mine, with low noise, low vibration, and high stability. They also wanted a crane that could be easily controlled and maintained, with advanced features such as Remote Control, overload protection, and emergency stop.
20 Ton Crane& Double Girder Overhead Crane With Hook Solution
Based on the customer’s needs, we recommended our QD model double girder overhead crane with hook. This model is one of our most popular products, with many advantages over other types of cranes.
The QD model double girder overhead crane with hook has the following parameters:
Lifting capacity: 20 tons
Span: up to 31.5 meters
Lifting height: up to 18 meters
Working class: A5-A7
Power supply: 380V/50Hz/3Phase or customized
The QD model double girder overhead crane with hook has the following features:
Strong structure: The main girders are made of high-quality steel plates, welded by automatic submerged arc welding. The end beams are equipped with buffer devices and anti-derailment devices. The hoist trolley runs smoothly on the girders, with low noise and low wear.
Powerful performance: The hoist is driven by a three-phase asynchronous motor, with variable frequency speed control. The hook can rotate 360 degrees, making it easy to adjust the position of the load. The lifting speed can reach up to 12 m/min, while the travelling speed can reach up to 40 m/min.
Easy operation: The crane can be controlled by a pendant or a wireless remote controller. The operator can choose the most comfortable and convenient way to operate the crane. The crane also has a display screen that shows the working status and parameters of the crane, such as load weight, speed, and position.
High safety: The crane is equipped with multiple safety devices, such as an overload limiter, limit switch, emergency stop button, anti-collision device, and warning light. These devices can prevent accidents and protect the operator and the load.
Low maintenance: The crane has a modular design, which makes it easy to install and disassemble. The components are standardized and interchangeable, which reduces the spare parts inventory and maintenance costs. The crane also has a long service life, with a low failure rate and high reliability.
We quoted the customer a competitive price for the QD model double girder overhead crane with hook, which included the cost of the crane, the installation, the testing, and the after-sales service.
The customer was very satisfied with our crane solution and agreed to place an order with us.
Advantages of 20 Ton Hook Double Girder Overhead Crane
The QD model double girder overhead crane with hook has many advantages over other types of cranes, especially for mining applications. Some of these advantages are:
High lifting capacity: The QD model double girder overhead crane with hook can lift to 20 tons of weight, which is suitable for handling heavy materials and equipment in the mine. It can also lift large and irregular-shaped loads, such as coal blocks, iron ore lumps, or mining machines.
Long span: The QD model double girder overhead crane with hook can span up to 31.5 meters, which is enough to cover a large area of the mine. It can also travel along long rails, which increases the working range and efficiency of the crane.
High working class: The QD model double girder overhead crane with hook has a high working class of A5-A7, which means it can work continuously and frequently in harsh environments. It can withstand high temperatures, dust, humidity, and corrosion in the mine, without affecting its performance or quality.
Advanced features: The QD model double girder overhead crane with hook has many advanced features that make it more convenient and safe to use. For example, it has a remote control that allows the operator to control the crane from a distance, avoiding potential hazards in the mine. It also has an overload protection that prevents the crane from lifting loads beyond its capacity, avoiding damage to the crane or the load.
Transport&Installation of the Mining Crane
After receiving the customer’s order confirmation and payment, we started to manufacture the QD model double girder overhead crane with hook according to their specifications. We used high-quality materials and advanced technology to ensure the quality and performance of the crane.
We finished the production of the crane within 40 days and arranged for its transport to Germany. We packed the crane components carefully and loaded them on trucks. We also provided the customer with detailed instructions on how to unload and assemble the crane.
We sent our engineers to Germany to assist the customer with the installation and testing of the crane. We followed strict standards and procedures to ensure the safety and accuracy of the installation. We also trained the customer’s staff on how to operate and maintain the crane properly.
We completed the installation and testing of the crane within 15 days and received positive feedback from the customer. They said they were very happy with our service and product quality. They also said they would recommend us to their friends and partners.
