What Is a Mobile Jib Crane?
A mobile jib crane is a self-propelled or manually movable lifting system featuring a rotating boom mounted on a mobile base. Designed for flexibility, it eliminates the need for permanent installations like foundations or wall supports. Key components include:
- Boom: Horizontal arm (3–10 meters) for load reach.
- Mobile Base: Equipped with wheels (rubber or steel) or tracks for movement.
- Hoist: Electric, hydraulic, or manual lifting mechanism.
- Counterweights: Ensure stability during operations.
Key Features:
- Load Capacity: 0.5–20 tons.
- Rotation: 180°–360°, depending on design.
- Mobility: Manual pushing, electric drive, or diesel-powered movement.
Industries: Construction, manufacturing, warehousing, and shipbuilding.
Popular Application Scenarios
A. Construction Sites
- Steel Erection: Lift and position beams, columns, and prefabricated modules.
- Equipment Maintenance: Hoist heavy machinery for repairs.
B. Manufacturing Workshops
- Assembly Lines: Transport components between workstations.
- Die Handling: Move molds in press shops with precision.
C. Warehousing
- Loading Docks: Unload trucks or reposition pallets in tight spaces.
D. Shipyards
- Engine Installation: Maneuver ship engines into place.
E. Event Setup
- Stage Equipment: Lift sound systems, lighting rigs, and stages.
How Mobile Jib Cranes Work
Step 1: Setup and Positioning
- Deploy stabilizers or outriggers to prevent tipping.
- Adjust the boom angle and length for optimal reach.
Step 2: Load Engagement
- Attach the load using hooks, slings, or magnetic lifts.
Step 3: Lifting and Movement
- Vertical Lift: The hoist raises the load via chain or wire rope.
- Horizontal Rotation: The boom swivels manually or via motorized slewing.
- Mobility: Move the crane to the target location using wheels/tracks.
Step 4: Load Release
- Lower the load and disengage the lifting tool.
Control Systems:
- Manual: Lever-operated hoists and push movement.
- Electric: Wireless remotes or cabin controls for precision.
Cost Comparison: Wall Mounted vs. Mobile Cranes
| Factor | Mobile Jib Crane | Wall Mounted Jib Crane |
|---|---|---|
| Initial Cost | 8,00050,000 | 30,000 |
| Installation | Minimal (no foundations) | Requires wall reinforcement |
| Mobility | High (relocatable) | Fixed position |
| Space Usage | Floor space needed | Zero floor footprint |
| Maintenance | Higher (tires, motors) | Lower (stationary parts) |
| Best For | Multi-site or outdoor operations | Repetitive tasks in fixed areas |
Cost-Benefit Insight:
Mobile cranes offer long-term savings for businesses needing frequent relocation.
Wall-mounted models suit budget-limited, space-constrained facilities.
Routine Maintenance Tips for Mobile Jib Cranes
Daily Checks
- Tires/Tracks: Inspect for wear, cracks, or pressure loss.
- Hydraulic Lines: Look for leaks or fraying.
- Brakes: Test parking and emergency brakes.
Weekly Tasks
- Lubrication: Grease slewing rings, pivot points, and wheel bearings.
- Bolt Tightening: Ensure all structural bolts are secure.
Monthly Inspections
- Wire Rope/Chain: Check for corrosion, kinks, or wear.
- Electrical Systems: Test sensors, limit switches, and remote controls.
Annual Overhaul
- Replace worn tires, hydraulic seals, or bearings.
- Recalibrate load sensors and safety systems.
FAQ
Q1: Can mobile jib cranes operate on uneven terrain?
A1: Yes, models with all-terrain tires or tracks handle gravel, grass, or slopes (up to 5° incline).
Q2: How long does a mobile jib crane last?
A2: 10–15 years with proper maintenance.
Q3: What types of hoists can be used?
A3: Both manual chain hoists and electric chain hoists can be mounted on the jib arm, depending on the load and required speed.
Q4: Where can mobile jib cranes be used?
A4: They are ideal for workshops, maintenance areas, machine loading zones, and small warehouses—anywhere temporary or flexible lifting is needed.
Q5: How is it powered?
A5: The crane itself is mechanical, but if equipped with an electric hoist, it requires a power source (usually 220V or 380V).
Q6: Is installation required?
A6: No fixed installation is needed. The crane is ready to use after assembly and can be moved between different workstations as needed.
Q7: Are mobile jib cranes safe?
A7: Yes, when operated within the rated load and following safety guidelines. Many models come with locking casters and overload protection.
Q8: Can it be customized?
A8: Yes. Arm length, lifting height, base dimensions, and hoist type can often be customized to meet specific application needs.
