Product Parameters

Key Components

1. Boom and Pivot Assembly

The boom is typically a welded steel I-beam or box-section designed to minimize deflection under 3 t loads. For floor- and wall-mounted cranes, a top-mounted pivot bearing allows the boom to swing smoothly. Articulating models add an elbow joint bearing (with grease lubrication points) for multi-section movement.

2. Mast or Wall Bracket

• Floor-Mounted: A heavy-duty steel mast welded to a base plate anchors to a concrete foundation. The base plate uses anchor bolts and leveling shims to ensure plumb alignment.
• Wall-Mounted: A gusseted bracket made of thick steel plates and heavy gussets secures to structural beams on the wall. Bracket welds are stress-relieved to prevent distortion.
• Mobile: A steel mast attaches to a wheeled base. For electric drive, the mast houses a battery compartment; for manual, a reinforced base includes locking casters.

Hoist and Trolley

A 3 ton jib crane typically uses an electric chain hoist or wire rope hoist. Key features:

• Electric Chain Hoist: Compact size, low headroom requirement, two-speed lift motor. Load limit is exactly 3 t.
• Wire Rope Hoist: Drum-mounted, multiple rope falls (4–8 falls) to achieve higher lift heights (up to 12 m). Multi-speed motor options for precise placement.
• The trolley travels smoothly along the top flange of the jib crane's boom using sealed roller bearings, which ensure low-friction movement and durability. Depending on operational needs, several trolley drive options are available. In manual push configurations, the operator physically pushes the load along the boom, suitable for lighter applications. For improved control and reduced effort, a geared push trolley uses hand-operated gearing to move the trolley along the beam. For higher efficiency and heavier loads, a powered trolley integrates an electric motor and gearbox to automate movement, allowing precise positioning with minimal operator input.

Controls and Power Supply

Controls for a 3 ton jib crane include:

Power is usually 380–400 V, 3-phase. Mobile cranes may use a 48 V battery pack or connect temporarily to ground power. Standard protections include fuses, circuit breakers, and ground-fault protection.

• Pendant Station: A wired push-button station with emergency-stop button. Cables run on a festoon system or cable reel along the jib.
• Wireless Remote: Handheld radio transmitter with dead-man push button. Receiver is mounted on the crab or mast.

Safety Devices

A compliant 3 ton jib crane includes the following safety features:

• Upper/Lower Limit Switches: Prevent the hoist from traveling beyond set points.
• Overload Limiter: Monitors load weight via load cell or motor current. Locks hoist if capacity is exceeded.
• Emergency Stop Buttons: Located on pendant, remote, and cabin. Immediately cut power to the hoist.
• Warning Horn and Flashing Beacon: Audible and visual alerts during crane motion.
• Hook Latch: Prevents load slippage. Must be inspected regularly.
• Fall Protection (for maintenance): Lanyard points on the mast for operator fall-arrest during service.

Features and Benefits

1. Increased Productivity

A 3 ton jib crane saves time by reducing forklift travel and manual handling. Operators can position loads in tight spaces with a few clicks of a button. The electric chain hoist moves parts at speeds of 0.5–10 m/min (lift) and 5–20 m/min (trolley), cutting cycle times.

2. Compact Footprint

These cranes require minimal floor or wall space. A wall-mounted 3 ton jib crane frees up aisles and loading areas. Floor-mounted cranes need only a small concrete pad. Mobile jib cranes fit into narrow corridors and can be moved out of the way when not in use.

3. Flexible Coverage

Choose a wall-travelling jib crane for long, narrow bays. Combine boom rotation with runway travel to cover multiple workstations. Articulating cranes let you reach around obstacles or machines.

4. Ergonomic Operation

The smooth acceleration and deceleration of both the hoist and the trolley eliminates shock to the load. Dual-speed hoists allow operators to handle delicate things in slow motion. Operators can avoid dangling cords by using wireless remotes.

5. Durable Construction

All steel frames are welded and stress-relieved to avoid distortion. Bearings and rollers use C3 or C4 grade sealed bearings for long life. The chain or wire rope is galvanized or lubricated for corrosion protection and reduced wear.

Precautions for Use

1. Proper Training

Only trained and authorized personnel should operate a 3 ton jib crane. Operators must understand load charts, swing paths, and emergency procedures.

2. Daily Pre-Operation Inspection

Walk around the crane before each shift. Check for loose bolts, chain or rope wear, hook deformation, and unusual noises during a test lift.

3. Verify Load Capacity

Never exceed the 3 t rated capacity. Ensure rigging hardware (slings, shackles) is sized for at least 5 t for safety. Always center the load under the hook.

4. Clear Working Area

Keep personnel and equipment out of the swing radius. Mark the floor with safety lines, especially in high-traffic zones.

5. Controlled Motion

Lift straight up, move at a steady speed, and lower smoothly. Avoid sudden starts or stops to reduce load sway.

6. Avoid Side Pulling

Never lift with the load off-center on the boom. Side pulling creates moments that can warp the mast or damage bearings.

7. Lockout/Tagout for Service

Before any maintenance, cut power at the main switch and lock it out. Tag the crane to prevent accidental reactivation.

8. Environmental Awareness

Do not operate in high winds (for wall-mounted units). Keep cranes clean in dusty or corrosive atmospheres. If exposed to moisture, ensure electrical enclosures remain sealed.

Selection Guidelines

1. Identify Lift Requirements

Determine the maximum load weight, lift height, and pickup/drop-off locations. A 3 t jib crane for sale typically handles pallet racks, engine components, or small assemblies. Define whether you need moderate lift height (up to 6 m) or extended heights (up to 12 m).

2. Choose the Right Mounting Style

• Wall-Mounted: Ideal when floor space is scarce and there is a strong structural wall.
• Floor-Mounted: Best for central lift points where wall support is not available. Requires a concrete foundation.
• Mobile: Offers temporary lift points. Choose when lifting needs change frequently.
• Wall-Travelling: Covers a long, linear area. Suitable for machine tool lines or paint booths.
• Articulating: Provides flexibility to reach around obstacles.

Select Boom Length and Swing Arc

Based on your workspace, pick a boom length that covers the lift zone without interfering with other equipment. Choose a swing arc (180°, 270°, 360°) to balance coverage and crane placement. For maximum coverage, a 360° rotation on a floor-mounted crane is preferred. For wall-mounted units, 180°–270° is typical.

Pick a Hoist Type

You can choose the right type of hoist for your needs:

• Chain Block:
• Electric Chain Hoist: Lower initial cost, compact design, low headroom. Suitable for lift heights ≤ 6 m.
• Wire Rope Hoist: Smooth lifting, handles higher lifts (up to 12 m). More expensive but better for frequent use.

Assess Duty Cycle

Consider how often you will run the crane. For heavy-duty or continuous service, choose components rated for higher duty class (ISO M5–M7). Less frequent lifts may use standard-duty chain hoists.

Confirm Power and Controls

Verify your facility’s power supply (380 V/400 V, 3-phase) and ensure crane control options (pendant, wireless remote, cabin) match your workflow. Mobile cranes need battery chargers or a generator.
