Inleiding tot die beginsel van stabiele haak van portaalkraan

Gantry cranes are known for their versatility and strength. They are capable of lifting and transporting a wide range of loads from small to extremely heavy objects. They are often equipped with a hoist mechanism that can be controlled by an operator to raise or lower the load, as well as move it horizontally along the gantry. Gantry cranes come in various configurations and sizes to accommodate different lifting requirements. Some portaal hyskrane are designed for outdoor use and are built to withstand harsh environmental conditions, while others are intended for indoor use in warehouses or production facilities.

Universal characteristics of gantry cranes

• Strong usability and wide range of applications
• The working system is great and users can make choices based on real usage conditions.
• Easy to operate and maintain
• Good load-bearing performance

Principle of stable hook of gantry crane

1. When the hanging object swings, you need to find a way to make the hanging object reach a relatively balanced state. This effect of balancing the hanging object should be achieved by controlling the large and small vehicles. This is the most basic skill for operators to operate stable hooks. However, the reason why the large and small vehicles need to be controlled is that the reason for the instability of the hanging objects is that when the operating mechanism of the large vehicle or small vehicle starts, this process suddenly changes from static to moving state. When the cart is started, it will swing laterally, and the trolley will swing longitudinally. If they are started together, they will swing diagonally.

2. When the hook is operated, the swing amplitude is large but the moment it swings back, the vehicle must follow the swing direction of the hook. When the hook and wire rope are pulled into a vertical position, the hook or hanging object will be acted upon by two balancing forces and will rebalance. At this time, keeping the speed of the vehicle and the hanging object the same and then moving forward together can maintain relative stability.

3. There are many ways to stabilize the hook of the crane, and each has its own operating essentials and techniques. There are moving stabilizer hooks and in-situ stabilizer hooks. When the hoisted object is in place, the swing amplitude of the hook is appropriately adjusted to reduce the inclination of the wire rope. This is called starting the stabilizer hook.
