What are the types of Jib Cranes?

The arm or boom of a jib crane extends off the main body of the crane to give additional reach, and it features a lattice construction to reduce the weight of an increased load. Jib cranes can perform repetitive lifting jobs efficiently in tiny work areas because of their design. They are incredibly adaptable and flexible cranes with a straightforward design that can lift anything from 250 lbs. to 15 tons.

Jib cranes come in a variety of designs, each of which is created to meet the demands of a particular lifting application. Jib cranes that stand alone and may be deployed in various locations are the most popular kind. Their design serves as the basis for several additional varieties of jib cranes, including articulating and wall-mounted models.

Jib cranes have the flexibility to be put in any kind of workspace because of their straightforward design. They are flexible and adaptable pieces of machinery that may be set up to meet the requirements of a tiny workstation, saving workers from having to lift heavy and unwieldy goods. Jib cranes are frequently used in conjunction with other pieces of machinery to increase the effectiveness of an application. Click here for Electrical Jib Crane.

Jib cranes are overhead lifting devices, like other cranes, that are fastened to a horizontal beam, the ceiling, a column, or a wall. They are also referred to as boom cranes in addition to jib cranes. The jib that supports the crane's lifting mechanism is essential to the jib crane's structural integrity.

1. Freestanding Crane Jib

The most popular kind of jib cranes are freestanding models, which can be used for both indoor and outdoor purposes. They frequently travel alongside bridge cranes. Depending on where they are, freestanding cranes can rotate 360 degrees and lift anything from a few pounds to many tons. Freestanding jib cranes' absence of location restrictions, increased rotational range, high capacity, and extended reach are their key advantages. Freestanding jib cranes come in three different designs: base plate mounted, foundation mounted, and sleeve insert installed.

1.1 Mounted Base Plate

A hefty layer of concrete with reinforced gussets is used to reinforce a freestanding jib crane that is bolted to a base plate. The framework enables the hoist to be placed over obstacles in the air by the jib crane's boom.

1.2 Mounts on a foundation

A welded steel plate at the base of the pole of a foundation-mounted freestanding jib crane is positioned on the top layer of concrete. A second concrete pour eliminates the requirement for gussets and adds additional support for the mast.

1.3 Sleeve Insert Mounted

Similar to the foundation type, a sleeve is erected on the first cement pour of a freestanding jib crane with the second pour enclosing the sleeve. The crane may be moved without cutting or harming the mast since its mast slides into the sleeve.

2. Articulating Jib Cranes

An articulating jib crane has a boom and a swivel arm in contrast to a standard jib crane. They can be positioned to reach loads around corners and barriers and can spin smoothly and consistently respond to load location. Articulating jib cranes can be fixed on a wall, the floor, the ceiling, or a bridge system.

The two arms' rotation can be locked, and there are three alternative arm lengths available.

The outside arm can swivel 360° while the main arm may rotate 200°, allowing it to reach inside of machinery and containers. Precision load positioning and spotting loads around obstacles are made feasible by the numerous configurations of articulating jib cranes.

3. Jib Cranes Mounted on Walls

Jib cranes that are wall-mounted do not need a foundation or floor space and are sometimes referred to as wall pillar or cantilever jib cranes. They can be situated near the underside of the lowest building structure to allow for optimum clearance beneath and above the boom, complementing a monorail or overhead bridge crane.

Jib cranes installed on walls fold away along the wall when not in use to avoid impeding or hindering production. They can support up to five tons of weight and have spans between 8 and 30 feet. Jib cranes for walls come in two different designs: cantilever and tie rod support.

3.1 Cantilever

The cantilever boom of a cantilever wall jib crane is perpendicular to the floor and is attached to the wall by two brackets. They provide the most clearance because of their full cantilever construction.

3.2 Supported by a tie rod

The most cost-effective way to supplement overhead and monorail cranes and hoists in bays, along walls, and columns is to use tie rod jib cranes. A tie rod-supported jib crane is attached to the wall or column by two brackets, just as in the cantilever design. The boom, which is parallel to the floor, is where the bottom bracket is fastened. The tie rod support is where the second bracket is fastened. Jib cranes installed on walls and supported by tie rods take up the most space yet generate the most force. Their construction enables the hoist to go the entire length of the beam.

4. Cranes with masts

Mast-type jib cranes have their top stabilized and their floors supported by the building's supports. Mast jib cranes utilize less floor space and no foundation holes than base plate-supported and foundation-supported jib cranes. Mast jib cranes are a particularly cost-effective lifting mechanism, similar to a tie rod-supported jib crane because the structure of the building does not need to be changed to accommodate them.

Mast jib cranes come in two different designs: full cantilever and drop cantilever. While drop cantilever kinds are fixed at a specific height below a building's ceiling, full cantilever types utilize the entire top space of the structure. Mast jib cranes can lift ten tons and rotate 360 degrees. Their spans range from ten to forty feet. The height of a boom can be measured as the distance from the ground to the building's peak.

5. Portable Jib Cranes

According to their design, portable jib cranes have a capacity of less than a half-ton and are mounted on a transportable base that may either be wheeled or forklifted. Because of the way portable jib cranes are made, only one person is required to transport heavy loads of items.

The design of a portable jib crane must prioritize stability without the need for additional security. Because of their modest weight and ease of movement, they can be placed close to a work area.

6. Mechanical Jib Crane

A portable jib crane with the addition of a hydraulic cylinder to raise and lower the crane's arm is known as a hydraulic jib crane. A hydraulic cylinder linked to the crane's boom is used by the lifting system of a hydraulic jib crane to raise and lower weights. Depending on the crane's design, the hydraulic system may be hand-pumped or powered by a battery.

A hydraulic jib crane's lifting mechanism can lift one ton when the boom is retracted and 500 pounds when the boom is extended.

Hydraulic lifting cranes can be installed on the floor and rotate 360 degrees in addition to being transportable. Floor-mounted hydraulic jib cranes can have an electric hoist or a hand pump, just like the mobile variant.

7. Wall Traveling Jib Crane

A wall-traveling jib crane moves along rails attached to a building's or other supporting structure's walls. They are made to move, lift, and carry loads throughout an entire structure. Wall-moving cranes use the vertical lifting mechanism of the crane to transport loads laterally.

Utilizing the entire working area while saving time and labor is the goal of wall-traveling jib cranes. Their lifting capacity ranges from a half-ton to ten tons but can be altered and customized to meet specific needs. Wall moving cranes are a supplemental feature or add-on for overhead cranes, just like other jib cranes.

8. Ceiling Mounted Jib Cranes

Jib cranes that are ceiling-mounted conserve floor space while offering a special lifting force. They can be either regular single boom or articulate models. They can be platform mounted or fixed to an immovable stationary mount so that they can service many workstations. Jib cranes mounted on ceilings have a one-ton lifting capacity, a 16-foot maximum span, and a 360° rotation range.

9. Jib Workstation Crane

Workstation jib cranes provide for increased production while maintaining worker security. They are positioned so that employees can move a workpiece onto other applications and manage it easily. Workstation jib cranes are offered in every mounting configuration that is possible to suit a given application's requirements.

Most workstation jib cranes are stand-alone, have a conventional height of 12 feet, and can rotate 360 degrees. Small jib cranes use square mounting plates with gussets, while big-capacity ones use hexagonal mounting plates and gussets. Mounting plates vary depending on the crane's capacity.

10. Jib Cranes Mounted on Trucks

Truck-mounted jib cranes are among the more adaptable and often used jib cranes; they have all the same features as wall- or floor-mounted jib cranes but can be moved to any position regardless of the terrain or weather. Jib cranes that are bolted to the bed of a trailer or vehicle are constructed of high-tensile strength steel. They have a telescopic boom that can be used to reach hard-to-reach areas including light poles, roofs, and power lines.

Construction is a key use for truck-mounted jib cranes. This kind of jib crane can hoist very huge loads and can be mounted on big trucks. They give construction teams the equipment necessary to quickly identify and utilize large, heavy supplies.
