1.Main beam

Main Beam Structure & Design
1)Type: Single girder (usually European-style box girder or I-beam design).
2)Material: Made of high-quality steel (Q235B/Q345B) for strength and durability.
3)Construction:
Welded box girder (most common for 10-ton capacity) – Provides rigidity and resists bending.
Reinforced ribs inside to prevent deformation under heavy loads.
Machined rails (or tracks) on the bottom flange for smooth trolley movement.

2.Lifting System

1)Safety Features
Overload Protection: Cuts power if >110% load detected.
Limit Switches: Prevents over-hoisting/lowering.
Double Braking: Primary + secondary brakes.
Anti-Sway Control (Optional): Reduces load swing.
2)How It Works (Step-by-Step)
Operator Input: Uses pendant/remote to activate hoist.
Motor Engagement: Powers the drum/chain sprocket.
Lifting/Lowering: Wire rope/chain winds/unwinds.
Trolley Movement: Hoist traverses beam via trolley motor.
Precision Placement: VFD ensures smooth positioning.

3.End carriage

1)Drive Configurations
Single Drive (One Motor):
Only one end truck is motorized (cost-effective for small spans).
Requires a tie rod to synchronize movement.
Dual Drive (Two Motors):
Both end trucks are motorized (better for spans >15m).
More precise control, less wheel slippage.
2)Safety & Alignment Features
Limit Switches: Stops crane at runway ends.
Anti-Climb Devices: Prevents derailment.
Lubrication System: Reduces wheel and rail wear.
Rail Sweepers: Clears debris from tracks.

4.Crane travelling mechanism

Key Engineering Considerations

Dual-end drive: Better synchronization, ideal for >15m spans
2)Wheel-Rail Interface:
Standard steel wheels for most applications
Polyurethane-coated wheels available for noise-sensitive environments
Flange design prevents derailment
3)Power Transmission:
Direct motor-to-gearbox coupling
Chain or shaft connections for multiple drive points
Torque-limiting couplings for overload protection

5.Trolley travelling mechanism

1)Drive System
Trolley Motor: 0.5-1.5kW AC motor (typically IP54/IP55 rated)
Reducer: Hardened helical gearbox (service factor ≥1.25)
Drive Wheels: 2-4 steel wheels (150-300mm diameter) with hardened treads
2)Support Structure
Trolley Frame: Welded steel construction with reinforced crossmembers
Guide Rollers: Side-mounted rollers prevent trolley skewing
Bumpers: Energy-absorbing end stops
3)Power Transmission
Festoon System: For pendant-controlled cranes
Conductor Bars: For radio remote systems
Cable Reel: Alternative for long travel distances

6.Crane wheel

1)Bearing & Lubrication
Bearing Type: Spherical roller bearing (22220 series)
Dynamic load rating: ≥150kN
C3 internal clearance for thermal expansion
2)Lubrication:
High-temperature lithium grease (NLGI 2)
Automatic lubrication system recommended
Regreasing interval: 400 operating hours

7.Crane Hook

Maintenance Requirements
1)Daily:
Check for cracks/deformation
Verify safety latch function
2)Monthly:
Measure hook throat spread (<5% increase)
Lubricate swivel mechanism
3)Annual:
Dye penetrant inspection
Bearing replacement (if play >1mm)

8.Motor

The crane is equipped with three independent motor systems:
1) Lifting motor - responsible for the vertical lifting of 10 tons of weight
2) Trolley running motor - controls the horizontal movement of the hook device along the main beam
3) Trolley travel motor - drives the entire crane to move longitudinally along the track

.

9.Sound and light alarm system & limit switch

1)Sound and Light Alarm System
Purpose:
Provides visual and audible warnings to alert operators and nearby personnel of potential hazards or abnormal conditions during crane operation.
2)Limit Switches
Purpose:
Automatically stop or slow crane movement when it reaches preset boundaries to prevent collisions or over-travel.

10.Safety Devices

1)Overload Protection System
Function: Prevents the crane from lifting loads exceeding 110% of its rated capacity (10 tons).
2)Emergency Stop (E-Stop) System
Function: Immediately cuts all power to the crane in emergencies.
3)Limit Switches (Travel & Hoisting Limits)
Hoisting Limit Switches
Upper Limit Switch
Stops the hoist before the hook reaches maximum height.
Often uses a rotary cam or proximity sensor.
Lower Limit Switch
Prevents the hook from overwinding the wire rope.
Typically a lever-arm mechanical switch.
4)Emergency Stop (E-Stop) System
Function: Immediately cuts all power to the crane in emergencies.
5)Insulated & Grounded Electrical System
Short-Circuit Protection (Circuit breakers & fuses).
Phase Failure Protection – Prevents motor burnout.
Lightning Protection (For outdoor installations).
6)Structural Safety Features
Buffer (Bumper) Pads – Absorbs impact at rail ends.
Anti-Derailment Guards – Prevents wheels from leaving rails.
Corrosion Protection – Epoxy-coated steel for humid environments.

Pre-set travel paths (for repetitive tasks).
Load positioning sensors (for precise placement).
Remote monitoring (via HMI or SCADA system).
