How to Install a Jib Crane?

The jib crane is a new generation of modernly produced light lifting equipment. Especially suitable for short distances, frequent use and intensive lifting operations.

5 ton Jib cranes work lightly. The crane consists of a column, a boom drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation through anchor bolts, and the swing arm is driven by a cycloid gear reducer. The electric hoist runs in a straight line from left to right on the I-beam of the rotating arm to lift. The lifting arm adopts a hollow steel structure, which is light in weight, large in span, large in lifting capacity, economical and durable. The built-in boom crane-type traveling mechanism adopts special engineering plastic traveling wheels and rolling bearings, which have low friction, fast moving speed and small structural size, which is especially helpful to increase the traveling distance of the hook.

Jib cranes are mainly used for moving, transporting and lifting goods in a small area. The lifting weight is generally less than 5 tons, and the arm can rotate 360 degrees around the column. This kind of jib crane is lightweight and easy to install, but there are still some precautions.

Cantilever cranes generally require a pre-embedded foundation at the installation location, that is, based on the basic parameters of the crane at the installation location. Dig holes and pour concrete with a certain strength in the holes. If necessary, steel bars can also be embedded in advance.

Before pouring concrete, it is necessary to prepare several sets of embedded bolts matching the cantilever crane, and fix the bolt positions before the concrete takes effect. The most important thing in this step is the positioning of the embedded parts. If the deviation is too large, when the equipment arrives at the site, the positions of the holes and the positions of the embedded parts will not match, making it impossible to install. Therefore, in order to ensure accurate installation, it is best to position according to the template when embedding.

What should you pay attention to when installing a cantilever crane?

After the equipment is transported to the site, the product and technical documents should be checked according to the packing list to see if there are any missing parts, bending and torsional deformation of the cantilever beam, and corrosion of the shaft caused during transportation. Bumps, etc. should be corrected or restored separately.

When installing the column, the column should be kept vertical to the ground. The screws of the foundation plate should be tightened firmly without any looseness. The floor and foundation should fit well. If an electric hoist is equipped, cables and grounding facilities should be pre-embedded. The pre-embedded cables should be connected from the foundation. Lead out from the center, and the grounding resistance should not be greater than 4 ohms.

To install cross beams, please proceed in the following order. First, lift the beam horizontally and insert the rotating shaft into the rotating drum from the upper and lower supporting plates. Then install the reducer on the pallet and install the electric hoist on the cantilever beam track. Finally, connect and install all electrical appliances on the beam, leaving a power cord of appropriate length.

When operating a 10 ton jib crane, all national safety regulations for crane use and operation should be followed. To ensure safety and avoid equipment damage, follow these safety practices: Jib cranes are not allowed to be used to transport people. Do not lift loads above personnel level. Pulling or pulling loads is not allowed. Overloading is not allowed. During normal operation, collision between the hook head and the limit switch should be avoided.

In addition, there are other important operating tips: the load hanger must be suspended from the trolley through a flexible connection. Rigid connections produce uncontrollable forces that eventually lead to fatigue fracture. When loading, do not pull on the flashlight door. When the arm is rotated manually, only the hook can be pulled. Do not pull on the flashlight door and cable. Fasteners on jib cranes should be inspected every 6 months.
