A jib crane is a versatile lifting device characterized by a horizontal jib mounted on a fixed or rotating column. It can rotate 180° to 360° within its working range, making it particularly suitable for lifting and moving materials in confined spaces and reaching areas that are difficult for conventional overhead cranes to access.
If you are looking for better equipment to handle repetitive lifting tasks in your workshop, loading dock, or production facility, a jib crane can help you save on capital investment and operating costs. This guide will explain the main components, types, and applications of jib cranes, and help you choose the right equipment.
Each jib crane has five main components that work together. The vertical column stands upright, supporting the overall weight. The horizontal cantilever extends from the column, covering your work area. The rotation system allows the cantilever to rotate in a full or partial circle. The lifting trolley slides along the cantilever, precisely positioning the load where needed. The base or anchor bolts securely fasten the entire assembly to the ground or wall.
High-quality manufacturers such as Вэйхуа Груп manufacture these components using high-strength steel that meets international quality standards (ISO 9001). The integrated quality of these components determines how much weight the jib crane can safely lift – industrial models typically range from 0.5 tons to 20 tons. The jib crane must withstand both the downward weight and the lateral forces during rotation.
The rotating system uses heavy-duty bearings, specifically designed for smooth rotation. More powerful models utilize special bearings that distribute the weight evenly in all directions. This design results in less wear and tear and allows for over 100,000 rotations with normal maintenance.
The lifting system uses either electric chain hoists или wire rope hoists, depending on the weight of your goods. Electric chain hoists are popular for loads ranging from 0.5 to 5 tons, being compact and easy to maintain. Wire rope hoists are more suitable for heavier loads up to 20 tons and offer faster lifting speeds.
The independent column jib crane is the most common choice. It is bolted directly to the concrete floor and can rotate a full 360° without hitting building walls or columns. Based on the installation method, column jib cranes are mainly divided into two types: fixed и mobile. Fixed columns are securely fixed to the ground, while mobile columns are mounted on a removable base for flexible positioning.
Weihua Group manufactures column jib cranes with lifting capacities ranging from 1 ton to 20 tons and jib lengths from 3 to 7 meters. They perform excellently in open workshop spaces, providing full coverage of the area around the crane. Your floor needs to be strong enough to withstand more than 150% of the crane's maximum rated load.

The articulated jib crane features a unique curved arm structure design on the jib, allowing for easy extension and rotation, providing simple and flexible operation and a wide working range. The articulated crane can flexibly avoid obstacles in confined work areas and adapt to complex working environments. With proper counterweight balancing, the total reach can extend up to 10 meters.
Articulated jib cranes are ideal for maintenance workshops and assembly areas where you need to move goods over equipment or walls. Weihua's articulated jib cranes can position loads with an accuracy of within 5 millimeters. They are equipped with sensors to prevent the jib from colliding with nearby equipment.
Wall-mounted cranes do not occupy any floor space. Weihua Group's BX series is installed on sturdy concrete or steel walls capable of withstanding tensile forces. Depending on the installation method, they can typically rotate from 180° to 270°.
Wall-mounted models have lifting capacities ranging from 0.25 tons to 3 tons, with the jib extending up to 4 meters from the wall. They are ideal for narrow aisles and crowded work areas. The installation height can be adjusted for greater comfort for workers during lifting operations.
Wall traveling jib cranes combine the advantages of a jib crane with the ability to move along a track. A traveling crane moves along a track mounted on the wall, covering a larger area equivalent to the work of three fixed cranes.
Weihua's wall traveling jib cranes can travel along the wall for 10 to 50 meters while still lifting 1 to 5 tons. They run on precision wheels with bearings that require virtually no lubrication. The travel speed is adjustable from 5 to 20 meters per minute, adapting to different operating rhythms.
Modern jib cranes utilize variable speed control for smooth starting and stopping. This reduces load swing by 60% compared to fixed speed control. Operators achieve faster cycle times while maintaining load stability during positioning.
Rotation speed is adjustable between 0.5 and 3 revolutions per minute, depending on the load weight and cantilever length. Weihua Group's advanced models feature programmable zone limits to prevent collisions with adjacent equipment or building columns.
An overload protection system continuously monitors the lifting weight using sensors. If the weight exceeds 105% of the crane's rated capacity, it automatically shuts down to prevent damage. The operator must manually restart the system after verifying everything is safe.
Emergency stop buttons are located on the ground and on the wireless remote control for easy access in emergencies. The electrical system complies with international crane safety standards (IEC 60204-32). Ground fault protection activates within 0.04 seconds if any electrical problems occur.
The frequency of component maintenance depends on the manufacturer's recommendations. Вэйхуа Груп recommends inspecting the slewing bearing and adding new grease every 500 operating hours. The lifting chain should be inspected every 1000 hours to ensure proper adjustment.
Modular design means technicians can replace worn parts without dismantling the entire crane. Commonly replaced parts such as brake pads and limit switches are stocked in regional warehouses for quick delivery. Advanced monitoring systems can predict when bearings need replacement before actual failure occurs.
Jib cranes are ideal for production work involving the repetitive lifting of the same type of items within a specific area. Assembly lines use wall-mounted units to keep parts at a comfortable working height, reducing worker fatigue by 40% compared to manual lifting. Automotive parts factories use column-mounted jib cranes at workstations to install engines and transmissions.
Machine shops install articulated jib cranes next to CNC machines to load raw materials and unload finished parts. Precise positioning allows for accuracy within 5 mm in delicate operations. Weihua Group's manufacturing customers report a 25% increase in work speed after adding dedicated jib crane workstations.

Cold storage facilities require special corrosion-resistant jib cranes that can operate at temperatures as low as -30°C. Sealed electrical components prevent moisture ingress, and special lubricants keep bearings running smoothly. Distribution centers handling over 500 shipments daily rely on jib cranes to maintain smooth workflow and prevent ground congestion.
Automotive repair shops use консольные краны to remove engines, repair transmissions, and replace heavy parts. 360° rotation means the vehicle doesn't need to be repeatedly moved during multi-step jobs. Column-mounted models rated at 2-3 tons can handle most passenger cars, while 5-ton equipment is suitable for commercial trucks.
Industrial maintenance workshops use articulated designs to reach inside machinery without complete disassembly. Dual-arm configurations allow technicians to work around installed equipment to remove pumps, motors, and gearboxes. With the proper assistance of a jib crane, maintenance technicians can complete repairs 30% faster.
Welding workstations use консольные краны to move heavy steel materials during assembly. Adjustable rotation speed allows for precise positioning of tack welds before final welding. Fabrication workshops processing structural steel beams utilize 5-10 ton pillar-mounted jib cranes with 6-7 meter booms.
Sheet metal workshops use lighter wall-mounted jib cranes for loading bending and shearing machines. The compact design saves valuable floor space while maintaining a smooth flow of materials. Weihua's manufacturing customers specify spark-resistant hoists when working near grinding and cutting operations.
