The mobile jib crane is a flexible and movable lifting solution designed for efficient material handling in various working environments. Unlike traditional fixed jib cranes, it is equipped with a mobile base that allows the crane to be easily relocated to different working areas, providing excellent flexibility and adaptability for production and maintenance operations.
Featuring a 360° rotating jib arm and an electric chain hoist or wire rope hoist, the crane can lift, move, and position loads with high precision. The counterweight design ensures stable operation during lifting tasks, while the compact structure allows it to work effectively in areas where overhead cranes cannot be installed.
Mobile jib cranes are widely used in factories, workshops, warehouses, equipment installation sites, and construction areas for loading, unloading, and small equipment handling. With easy operation, large working coverage, and convenient mobility, they are an ideal choice for improving lifting efficiency and maintaining smooth production processes.
Before operating the mobile jib crane, operators should receive proper training and fully understand the equipment structure, operating methods, and load capacity. The crane must always be operated according to the manufacturer’s instructions, and overloading is strictly prohibited to ensure safe and stable operation.
Before starting any lifting operation, all supporting legs or stabilizing devices must be properly deployed and firmly placed on the ground. This provides additional stability for the crane and prevents movement or tipping during lifting tasks, especially when handling heavier loads.
During lifting operations, operators should avoid frequent inching or repeated start-stop actions of the electric hoist, as this may cause unnecessary impact on the motor and lifting mechanism. Smooth and controlled operation helps extend the service life of the mobile jib crane and improves safety.
Chains, wire ropes, hooks, and other lifting accessories must have sufficient strength and be in good working condition before operation. Any damaged or worn components should be replaced immediately. When lifting loads with sharp edges, protective pads should be used to prevent damage to the lifting equipment. The sling should always be positioned correctly in the center of the hook to avoid slipping.
The load should always be lifted and moved vertically. Side pulling, diagonal lifting, dragging, or using the jib structure to push or pull objects is not allowed, as these actions may damage the crane structure and create safety risks.
During lifting operations, no personnel should stand, pass, or work underneath the suspended load. Operators should ensure that the surrounding area is clear before moving or lowering heavy objects.
After completing work, do not leave loads suspended in the air. The load should be safely lowered to the ground, and the power supply should be switched off when the equipment is not in use. Regular inspection and maintenance are also recommended to keep the mobile jib crane in safe working condition.
Proper maintenance and regular inspection are essential to ensure the safe operation, reliable performance, and long service life of the jib crane on wheels. A well-maintained crane can reduce unexpected failures, minimize downtime, and maintain stable lifting performance during daily operations.
The rotating parts and mechanical joints of the jib crane on wheels should be lubricated regularly to reduce friction and wear. It is recommended to apply suitable lubricating grease to the rotation mechanism, bearings, and other moving components at least once every six months. Proper lubrication helps ensure smooth rotation, reduces operating resistance, and extends the service life of key components.
During long-term operation, dust, oil stains, and other contaminants may accumulate on the rotating parts, beams, and travel surfaces. These areas should be cleaned regularly according to the actual working environment. Keeping the moving surfaces clean helps maintain smooth movement and prevents damage caused by accumulated debris.
For jib crane on wheels used outdoors, the steel structure is exposed to sunlight, rain, and humidity, which may cause corrosion over time. Regular surface inspection and protective painting are necessary to maintain structural strength and appearance. Outdoor cranes are generally recommended to be repainted once a year, while indoor cranes can be repainted approximately every two years depending on the working environment.
Operators should regularly check important components, including the jib arm, support structure, hooks, lifting chains or wire ropes, wheels, and braking system. Any cracks, deformation, abnormal wear, or loose connections should be repaired immediately to prevent safety hazards.
When the jib crane on wheels is not in use for an extended period, it should be stored in a dry and clean environment whenever possible. Regular maintenance records should be kept to track inspections, lubrication, repairs, and replacement of parts, ensuring the Mobile Jib Crane remains in optimal operating condition.
