The small crane is an ideal lifting device that is flexible, easy to operate, efficient and reliable. It is especially suitable for engineering operations. Especially in the field of lifting, steel, timber market and narrow construction sites, small cranes can give full play to their strengths. Proper use of small cranes can reduce machine wear and prevent malfunctions. So, what is the operation method when working on a small crane?

The “cross” operation method for lifting cranes for small cranes:
When transporting small pieces of equipment and materials, due to the short distance or inconvenient use of mechanical transportation, it can be carried out by two or more people by lifting. During operation, the bars and ropes used must be solid and suitable, and the small crane operators require consistent steps, a unified command, and reasonable load distribution.
In the case where the lifting weight and the lifting height are not large, the weight can be picked up using a crowbar. The trick is to use the principle of leverage to achieve the goal of saving effort. Therefore, the fulcrum of the crowbar should be as close as possible to the heavy object, and the fulcrum should be hard. The crowbar can be used to raise the member so that the plank or the brick is underneath, or the mat can be repeatedly rubbed to raise the weight or drop the weight in the opposite manner.
Bundling refers to the operation of tying, moving or fixing objects with ropes and chains. The bundling method and lifting point are fully considered based on factors such as the weight, the geometry of the object, the position of the center of gravity, the ease with which the object is deformed, and the process requirements for the hoisting. The binding position should ensure the stability and balance of the hanger. The selected binding position should ensure that it does not plastically deform due to the weight of the hanger. Vertically lifting the long members should be bundled on the upper part of the center of gravity of the object; when the objects need to be hoisted in a horizontal position, they should be bundled symmetrically on both sides of the center of gravity. The bundle should be firm and firm, and the ropes of each strand should be evenly stressed. When attaching an angular object, it should be padded with soft objects at the corners.
Hanging refers to the operation of hooking after the object is bundled. The general hooking method includes a single rope buckle hook, a middle rope hook, a back buckle hook, a pressure rope hook, and the like. When hooking, pay attention to the center position of the hanger and the ropes are not evenly distributed. Under the action of inertial force and other external forces, the rope should not be displaced or squeezed.
The top of a small crane is the operation of jacking up heavy objects with a jack. This method is simple, easy, safe, and labor-saving. Especially for large objects, small cranes can give full play to their advantages when large cranes are difficult to display or costly.
Hanging refers to the operation of lifting a heavy object and placing it in a designated position with a lifting mast and a small crane. This is the most common way of vertical transportation. It is characterized by large lifting capacity, rising height, wide working surface, high speed and high efficiency.
Slip refers to the operation of placing heavy objects on the slides and pulling them by mechanical or manual force to make the weights slip. Generally, it is used for short-distance movement or equipment unloading. In order to reduce the friction, a rail is usually used as a slide rail, a slide is placed between the rail and the weight, and the rail is coated with lubricating oil.jib crane manufacturers
Rolling is a method of moving heavy objects by rolling of the rollers, and is usually used for short-distance horizontal transportation.
The rotation is a method of rotating the weight in a plane at a certain angle. The roller and the raceway can be rotated under the weight, or a special rotary table can be set to rotate the heavy object.
Roll refers to the operation method of using a rope to cover a cylindrical object and pulling the rope to roll or lower the object. It is often used for loading or unloading steel pipes, concrete pipes or electric poles.
