Gantry crane structure mainly includes three parts, lifting mechanism, hoist travelling mechanism and the crane travelling mechanism. There three parts forms the crane working area. AIMIX Group, a famous gantry cranes manufacturer, produces types of cranes with best quality and price. According to gantry crane design standards, our company designs lifting gantries with good appearance and simple structure. Thus our gantry crane is simple to install and operate, easy to disassemble, convenient to maintain, fast to carry.
What’s lifting mechanism of gantry crane system?
Lifting mechanism is installed on the trolley, it is composed of electric motor, coupling, transmission shaft, brake, reducer, drum, trolley, wire rope and hook assembly. When the lifting mechanism is connected to the power supply, brake releases. With motor’s forward or reverse turn, the power (torque) transports to reducer through coupling, transmission shaft, coupling with brake wheel, it reduces speed, and turns the high speed and low torque into low speed and large torque, so that to drive the drum turn. Both ends of the whole wire rope wears round fixed pulley hook, then respectively fixed at the two ends of drum, due to the drum’s forward and reverse turn, the pulley hook lifts up and down, so as to lift material up and down.
How does trolley travelling mechanism work?
First start the trolley mechanism, the electric motor is connected to power, and the brake releases. Motive power transmits to reducer through coupling, it can turn motor’s high speed and low torque into low speed and large torque, thus the reducer has the function that reduces the speed and increases the torque. The torque from reducer transports through transmission shaft and drives the wheels run on the rail, so that trolley travels on the rail right and left horizontally.
What’s function of crane travelling mechanism?
Common crane travelling mechanism has four wheels, which are set under the lower cross beam. When the wheel pressure increases, more wheels are needed. Crane travelling device can achieve lifting along the rail direction, back and fro. It has two drive way, centralized drive and respective drive. Centralized drive is suitable for small span, light duty. Thus most industrial cranes adopt respective drive, not centralized drive.
Getting to know the gantry crane parts
There are different kinds of gantry cranes, which means some may have more parts than others. But the most basic gantry crane structure has three core components. The first is the parallel runways with a bridge that spans the entire length of the gap. Along this bridge travels the second component, which is the hoist. This does the heavy lifting of materials. The last core component is the supporting structure, which are usually vertical legs. Other types of gantry cranes only have one leg and the other end is attached to a wall or another structure.
You can find gantry cranes with wheels. These portable cranes are typically found in smaller facilities where loads are not that heavy. The advantage to using this is that the crane can be easily moved from one place to another. Effectively, this means that the operating area isn’t as limited compared to a fixed gantry crane. The load doesn’t need to be brought near the crane. Instead, you have the option of moving the crane closer to the load.
It is also worthy to note that most modern gantry cranes come with a lot of electrical parts. These are necessary to provide high level of control and safety. When one of these electrical components fail, the entire gantry crane structure may stop working. The other parts of the gantry crane include bridge wheels, brakes, hydraulic systems, wire ropes and below-the-hook devices.
