Installation of floor mounted jib cranes

The floor mounted jib crane is a type of lightduty crane that boasts several features such as light weight, large span, high lifting capacity, economical and durable. It has a high mechanical efficiency, is easy to install, use and maintain, and comes with low costs. Now, let's take a better look at the structures of the floor mounted jib crane.

The primary structure of a floormounted jib crane is composed of a vertical pillar or post mounted on a foundation and a horizontal jib arm that extends from the pillar. The jib arm has a pivot point that connects it to the pillar, allowing it to rotate.

floor mounted jib cranes main parts and components 

The components of a floor mounted jib crane include the following:

• Pillar: The vertical structure that supports the jib arm and permits it to rotate.
• Jib arm: The horizontal structure that extends from the pillar and holds the hoist and trolley.
• Pivot point: The connection between the pillar and jib arm that allows the jib arm to rotate.
• Hoist: The component that lifts and lowers the load.
• Trolley: The component that moves the hoist along the length of the jib arm.
• Control system: The component that enables the operator to regulate the crane's movement.
• Foundation: The base on which the pillar is mounted that provides stability for the crane.

Floor mounted jib crane structure:

• The pillar of the slewing jib crane is made of a circular tube with the base plate and the ends of the rotating shaft welded to it, and an upper waist ring track fitted. To ensure the crane's stability, the base plate is secured to the cement ground with chemical bolts. To conceal the cable inside the column, a through hole is made on the spinning shaft. The spinning shaft can be equipped with a 360degree collector, allowing the jib to rotate 360 degrees. The floor mounted  jib crane rotates on the waist ring track. Several tiny holes are drilled in the track to accommodate rotation restriction blocks with a 0360 degree angle constraint.
• The slewing jib's arm is made up of Ibeam and Hbeam. It is suitable for installing and operating various chain hoists. A moveable locking device is put at both ends of the hoist to ensure that it operates within a specific stroke.
• The  electric slewing jib crane's support bracket is welded with rectangular steel pipes and steel plates that support the jib. Superior mechanical structure, triangular support, small weight, and great safety. Under the bracket, there are two revolving wheels. The floor mounted jib crane's electric rotation is achieved by driving the active wheel with a lightduty worm gear reducer motor.
• To accomplish free rotation of the jib, the rotation mechanism of the floormounted jib crane uses a circular tube as the housing and installs a selfaligning roller bearing within. Because of the performance of the selfaligning roller bearing, even if there is a little variation in concentricity between the waist ring and the pillar, the slewing jib crane can be used safely.
• For attaching power cables for electric hoists, the Cshaped track can be mounted on the rotating arm of the slewing jib crane. It has a modest and lovely appearance as well as a wide range of applications.

Installation procedures of floor mounted jib crane

Here's a general guide to putting in a floormounted jib crane:

• Select a location: The first step is to determine where the floor mounted jib crane will be positioned. The site should be level, strong, and capable of supporting the weight of the crane and the cargo it will be hauling.
• Prepare the foundation: The next stage is to prepare the crane's foundation. To construct a stable basis for the crane, a pit must be dug and concrete poured. The size and depth of the foundation will be determined by the crane's size and weight.

• Install the pillar: The pillar can be erected after the foundation has been constructed. To maintain stability, the pillar should be securely attached to the foundation.
• Install the jib arm: The jib arm should now be installed onto the pillar. The jib arm should be properly aligned with the pillar and securely secured in place.
• Install the hoist: The last step is to attach the hoist to the jib arm. To ensure safe functioning, the hoist should be firmly linked to the jib arm and correctly wired.
• Test the crane: After the installation is complete, it is critical to test the crane to check that it is operational. This entails lifting a test load and ensuring that the crane can move smoothly and safely.

It is critical to remember that the installation of a floor mounted jib crane should only be performed by competent specialists who have prior expertise installing and operating these types of cranes. To ensure safe and effective operation, all safety recommendations and regulations must be followed when installing and operating a floor mounted jib crane.
