Articulating Jib Cranes

Articulating jib cranes combine the compact footprint of standard jib cranes with an adjustable articulating arm that extends reach and flexibility. These cranes pivot at multiple hinge points, allowing operators to position loads around structural obstacles and into tight work cells. Typical load capacities range from 0.25t to 3t, with boom lengths up to 10m and lift heights to match workstation elevations. Designed for precision handling in manufacturing, maintenance, and assembly environments, articulating jib cranes support tasks such as machine tending, parts staging, and inventory replenishment. Their ability to fold the boom flush against a mast or wall when not in use saves floor space, making them ideal for congested factory floors or cleanroom applications.

Types Of Articulating Jib Cranes

Articulating jib cranes come in several mounting styles to suit different facility layouts and workflows. Each mounting style enables the crane to reach into confined or offset positions, allowing precise handling of parts, tools, or components.

1. Floor‑Mounted Articulating Jib Crane

A free‑standing pedestal supports a multi‑hinge boom that swings through 180° or more. These cranes provide robust coverage over a circular or semi‑circular work area and handle loads up to 5t.

2. Wall‑Mounted Articulating Jib Crane

Bolted directly to a building column or reinforced wall bracket, wall‑mounted articulated jib cranes (often called articulating wall jib cranes) pivot at the mast and elbow joint. They save floor space while delivering a combined boom outreach of up to 6 m and capacities from 0.25t to 2t.

3. Ceiling‑Mounted Articulating Jib Crane

Suspended from overhead beams or runway structures, these cranes integrate articulating booms with under‑hung rails. They free the floor entirely and extend reach across multiple workstations without limiting aisle traffic​.

4. Portable Articulating Jib Crane

A mobile base or wheeled frame carries the articulating jib, allowing operators to move the crane between bays or production cells. Portable articulating jib cranes serve maintenance and field service applications where fixed mounting is impractical​.

5. Wall Travelling Articulating Jib Crane

Combining a wall‑mounted articulating boom with a wall runway system, this design allows the crane to traverse along the wall while the boom pivots. This maximizes coverage along long production lines or assembly cells.

Structure And Design

An articulating jib crane features a segmented, jointed arm structure that allows enhanced flexibility and maneuverability in tight or obstructed spaces. Unlike traditional jib cranes with a single rigid boom, it has two or more pivoting arms connected by joints. The main arm, mounted to a fixed base such as a floor post, wall bracket, or ceiling, rotates horizontally, while a secondary arm attached at a midpoint joint moves independently, allowing the crane to reach around obstacles and into confined areas. A manual or electric hoist, often on a trolley, travels along the arm for precise load handling. Bearings at the joints ensure smooth motion, and optional brakes or dampers aid in control. Built from steel or aluminum depending on the application and are designed for light to medium-duty tasks, offering compact, ergonomic lifting solutions without needing large footprints or overhead runway systems.

1. Articulating Boom Assembly

The defining feature is the multi‑section boom, which consists of pin‑connected segments—typically two or three—that fold together. Hydraulic or manual linkages control the elbow joint, enabling extension and retraction of the articulating arm​. Finite element analysis determines the optimal boom section dimensions for stiffness and minimal deflection under load​.

2. Mast And Support

• Floor‑Mounted Masts are heavy‑wall tubular steel or I‑beam columns anchored to reinforced floor plates or foundation pads. Bracing ensures stability against dynamic loads.
• Wall Brackets use structural steel channels and gusset plates bolted into concrete or steel columns. Design loads follow guidelines in ANSI B30.11 and AISC steel construction standards​.
• Ceiling Attachments include rigid hangers or modular runway connections that distribute load into existing overhead crane girders or roof trusses.

3. Hoist And Trolley Integration

An electric chain or wire rope hoist mounts directly to the articulating boom, either on a fixed trolley or a motorized rack‑and‑pinion carriage for extended outreach​. Chain hoists are common for low‑headroom and light‑capacity units, while wire rope hoists suit higher lift heights and heavier loads.

Features

Articulating jib cranes offer a range of advanced features designed to enhance functionality, precision, and user comfort. Their extended coverage and reach stem from a foldable boom that tucks neatly against the mast when not in use, minimizing the crane’s footprint. When deployed, the articulated arms can maneuver loads around obstacles, over barriers, or into enclosed spaces with ease. Precision load positioning is achieved through dual-speed hoists—high speed for movement and low speed for accurate placement—along with multi-pivot joints that enable ±3 mm positioning repeatability in inching mode. Ergonomics are prioritized through intuitive pendant or joystick controls and spring-assisted joints or counterbalanced booms, reducing operator effort and fatigue. Additionally, the modular construction of these cranes allows for quick field replacement of components like boom sections or hoists, while standardized brackets make it easy to retrofit the articulating arm onto existing crane mounts, enhancing long-term flexibility and serviceability.

Advantages of Articulating Jib Cranes

• Articulating jib cranes enhance space efficiency by reclaiming floor space that would otherwise be occupied by fixed-reach jibs or floor cranes. Their ability to fold the boom into a compact profile when not in use reduces obstruction in aisles and work zones, allowing for better utilization of the available workspace.
• Their pivot‑and‑fold mechanism lets a single unit service multiple adjacent stations or work cells, and when mounted on a wall‑travelling or ceiling‑mounted system, one crane can cover the same area that would ordinarily require several fixed‑reach jibs.
• The unique design of the articulated jib crane enables the equipment to serve multiple workstations, allowing operators to quickly reposition parts within the working area without moving the load or leaving the workstation, thereby simplifying the workflow. According to industry surveys, the assembly cycle has been shortened by an average of 20%.
• Pin‑style boom joints with positive locking pins prevent unintentional folding. Overload protection, limit switches, and emergency stops comply with OSHA 1910.179 requirements for articulating cranes equipped with hoists manufactured after December 31, 1999​.

The Application of Articulating Jib Cranes

1. Machine Tending

Articulating jib cranes streamline the loading and unloading of CNC mills, lathes, and press brakes by placing raw or finished parts directly into chucks and fixtures. This reduces manual handling, shortens cycle times, and keeps operators clear of pinch points during tool changes.

2. Parts Staging

In automotive, appliance and electronics assembly lines, these cranes deliver components precisely where needed to support just‑in‑time workflows. By bringing parts to the operator rather than moving the operator to the parts, they help maintain a steady production rhythm and minimize work‑in‑progress inventory.

3. Maintenance and Repair

Portable articulating jib cranes provide vertical lifting capability in maintenance bays that lack overhead runways. Technicians use them to raise pumps, motors and gearboxes safely and efficiently, allowing maintenance tasks to proceed without the delays or hazards of improvised lifting methods.

4. Assembly of Irregular Parts

The two‑pivot boom design accommodates parts with complex shapes—such as pressure vessels, fuselage sections and composite molds—by independently adjusting reach and pivot angle. This flexibility lets operators position heavy or awkward components without repositioning the crane base or surrounding equipment.

5. Inventory Handling

Wall‑mounted articulating jib cranes assist with stock replenishment on mezzanines and shelving units in narrow aisles. Their compact footprint and swing‑arm reach allow them to serve areas that forklifts or pallet jacks cannot access, improving material flow in multi‑level racking environments.
