What dimensions are important when purchasing a floor mounted jib crane?

  • Floor mounted jib crane lifting capacity. The weight of the heaviest load to be lifted,, that is , the lifting capacity of the floor mounted jib crane, is one of the most important dimension needed on jib crane designing.
  • Jib crane travelling length. How far the electric hoist can travelling along the jib crane arm or the jib cantilever is the jib crane travelling length, which is also a very important dimension.
  • Jib crane lifting height: How high does the load have to be lifted? That is the lifting height of the jib crane.

With the there’s also a need for some margins on the design to allow machinery of the jib crane to fit in the space as well. Most floor mounted jib cranes will have a electric hoist of approximately 24” height as well as a cantilever of approximately 12” height. That is to say, the lowest obstructions above the required load height are 42” including electric hoist, cantilever, and required 6” safety margin. What’s more, , because the load cannot be travelled along the jib crane cantilever all the way to the edge, a 3” must be left at the moving end of the crane cantilever and minimum 12” must be left at the stationary end of the cantilever to accommodate the crane pillar, bearing, hinge, wall, and any other obstructions.36eHenan Dongqi Machinery Co., Ltd

What Rotation options are available on a Floor mounted jib crane?

A floor mounted jib crane covers an area by rotating instead of travelling.Most customers prefer to have as much area covered by the rotation of one jib as is possible. However, some customers may prefer to limit the rotation of a floor mounted jib crane. For a small additional sum, rotation stops can be installed on most floor-mounted floor mounted jib cranes.36eHenan Dongqi Machinery Co., Ltd

  • For example, the crane buyer in a machine shop with a computerized machining center next to a floor mounted jib crane does not want the floor mounted jib crane to be able to rotate into the neighboring CNC machine. Also, some crane buyers will require different electrification options such as a “top entry collector” or “bottom entry collector” depending on the rotation types.
  • This decision will be made by the jib crane engineer because each option has a more appropriate application. Collectors of this nature help make jibs more flexible because these collectors allow unlimited rotation in one direction.
  • Finally, the boom can be motorized itself. This option is expensive and is usually used in heavy duty jib crane or high-capacity jib crane applications. Pipe pit-casting applications typically see powered rotation jibs – in fact, the first overhead crane in the world was a motorized pit-cast floor mounted jib crane in Birmingham, Alabama.

Why aren’t the rotation motion and traverse motion powered usually?

It’s common to see the electric hoist motion powered on a floor mounted jib crane. However, it is rare to find the traverse(trolley) and rotation motions powered. Many times the floor mounted jib crane is purchased as a cost-effective lifting tools to cover a small workstation, whereparts are lifted by the floor mounted jib crane and mounted into machines and also bolted on to larger assemblies. The finished piece is then transported to the next workstation by the overhead crane. That is to say, for movements of more than five to ten feet, the overhead crane is used. Many times crane buyers do not feel the floor mounted jib crane also needs to be motorized, that the crane operator can gently push the load to nearby machines and workbenches. For crane buyers that do want a motorized floor mounted jib crane, both rotation and traverse(trolley) motions are available as powered motions at extra cost.36eHenan Dongqi Machinery Co., Ltd

How Does a Floor mounted jib crane Work?

A floor mounted jib crane will always rotate and a floor mounted jib crane will always lift or support a load. Most floor mounted jib cranes will also have a third motion, that of traverse: The load will be able to traverse the cantilever from the center of the circle to the edge of the circle created by the jib as the jib rotates. Floor mounted jib cranes typically have a hand-powered rotation and traverse motion, while it is common to see either electric-powered or hand-powered lift motion. The hand-powered rotation and traverse motion are accomplished by push/pull, while the hand-powered lifting is accomplished by a chain similar to a non-powered garage door. Options for electric rotation and traverse are available on almost all floor mounted jib cranes for those wishing to purchase such a liftingcrane.36eHenan Dongqi Machinery Co., Ltd

Foundation footing design of floor mounted jib cranes

Floor mounted floor mounted jib cranes need to be mounted properly or the jib crane will collapse, resulting in damage to the load as well as human injury or death. A small selection of floor mounted jib cranes can be mounted straight to a 6” reinforced concrete floor, the industrial building standard. The rest of the floor-mounted floor mounted jib crane range must have a square of factory floor torn up and a specially-designed concrete footing installed.36eHenan Dongqi Machinery Co., Ltd
How do I determine if my floor mounted jib crane needs a foundation? Plan on needing a foundation unless your jib crane engineer tells you specifically otherwise. How do I know how big to make that pillar foundation? Dongqi Hoist and Crane will supply you with a drawing showing the length, depth, and width of the pillar foundation required, as well as any reinforcement required and the anchor bolt placement. Dongqi Hoist and Crane also offers a kit consisting of anchor bolts, anchor bolt template, and early kit shipment so the customer can set the jib crane foundation including anchor bolts before the actual floor mounted jib crane arrives.36eHenan Dongqi Machinery Co., Ltd

What install a Floor mounted jib crane to the Floor?

A floor mounted jib crane is anchored to the foundation or wall with anchors that can be ordered with the floor mounted jib crane or purchased by the customer at a local bolt or supply house. It is important that the floor mounted jib crane be anchored to a proper concrete footing or properly engineered wall or building column. Bolts alone cannot anchor most floor mounted jib cranes into industry standard 6” reinforced concrete floor. The floor will buckle, the jib crane will collapse, loads and/or people will be hurt. If you have any questions, please call our office first or reference your owners’ manual supplied with every floor mounted jib crane. A floor mounted jib crane is easy to install provided the directions are followed carefully. Most customers prefer to install their own floor mounted jib cranes but installation is available through Floor mounted jib crane Outlet installation field crews.36eHenan Dongqi Machinery Co., Ltd
