BZY type portable 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.

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.

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-Benefit Insight:

Mobile cranes offer long-term savings for businesses needing frequent relocation.

Wall-mounted models suit budget-limited, space-constrained facilities.

Step 1: Site Preparation

• Clear debris and ensure a level surface.
• Verify overhead clearance (≥1 meter above boom height).

Step 2: Stabilization

• Deploy outriggers or stabilizer legs.
• Lock wheels/tracks to prevent unintended movement.

Step 3: Boom Configuration

• Extend or retract the boom to the desired length.
• Secure locking pins or hydraulic clamps.

Step 4: Power Connection

• For electric models, connect to a compatible power source (220–480V).
• Test emergency stop buttons and controls.

Step 5: Load Testing

• Perform a 125% SWL static test for 10 minutes.
• Conduct dynamic tests with 110% SWL.

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.

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.
