1.Main beam

Main Beam Overview (10 Ton Single Girder)
Type:
Single girder: Only one main beam across the span (vs. double girder)

Typically box-type or I-beam/truss-type structure, depending on span and usage

Material:
High-strength structural steel, such as Q235B or Q345B (China) or equivalent international standards (e.g., ASTM A36)

 

2.Lifting System

Electric Hoist:Main unit for lifting and lowering the load
Wire Rope & Hook:Transfers the lifting motion to the load
Trolley Mechanism:Moves the hoist left-right along the girder
Motor(s):Drives lifting and trolley movement; usually separate motors
Gearbox:Transfers motor torque and reduces speed
Braking System:Holds the load when the motor stops
Limit Switches:Prevents over-lifting or over-lowering
Control Panel:Coordinates power, control, and safety features

3.End carriage

The end carriage of a 10-ton A-frame single girder gantry crane is a crucial structural and mechanical component. It connects the main beam (girder) to the supporting legs (A-frames) and enables the crane to travel along rails or wheels on the ground.
What Is the End Carriage?
The end carriage (also called end truck) is a wheeled frame located at both ends of the main beam, forming the traveling base of the crane. It houses the wheels, motors, and sometimes gearboxes, allowing the crane to move forward and backward along its runway.

                                         

4.Crane travelling mechanism

The crane traveling mechanism of a 10-ton A-frame single girder gantry crane is the system responsible for moving the entire crane structure along its working area - either on rails or directly on the ground (if rubber-tyred). It's essential for horizontal movement and positioning of loads.

5.Trolley travelling mechanism

The trolley traveling mechanism of a 10-ton A-frame single girder gantry crane is responsible for moving the hoist (lifting unit) horizontally along the main beam (girder). It enables precise lateral positioning of the load beneath the crane span.
It's the horizontal motion system that allows the hoist to move left and right along the single girder. This system is usually integrated with the hoist itself, especially in single girder cranes - meaning it's part of the electric wire rope hoist or electric chain hoist.

6.Crane wheel

The wheel of a 10-ton A-frame single girder gantry crane is a vital mechanical component that allows the crane to move along its runway (typically rail-mounted or trackless). These wheels are mounted on the end carriages and support the entire crane structure during travel.
Function of the Crane Wheels
Support and guide the crane during travel

Transfer the crane's load to the ground or rails

Ensure smooth, stable movement of the crane

Withstand heavy vertical loads and lateral forces

7.Crane Hook

The hook of a 10-ton A-frame single girder gantry crane is the final load-bearing element of the lifting system. It connects the load to the hoist and must be strong, safe, and compliant with industrial standards. Here's a detailed breakdown of this crucial component:
Purpose of the Hook
Transfers lifting force from wire rope or chain to the load

Enables easy attachment/detachment of lifting slings, chains, or direct loads

Designed to rotate, swivel, and pivot (in many cases) for load alignment

8.Motor

Hoisting motor:Lifts and lowers the load via wire rope or chain
Trolley travel motor:Moves the hoist left/right along the girder
Crane travel motor:Moves the crane structure along the ground or rails

Each motor is selected based on its load requirement, duty cycle, and operating speed.

9.Sound and light alarm system & limit switch

For a 10-ton A-frame single girder gantry crane, the Sound and Light Alarm System and Limit Switches are essential safety components that help prevent accidents, protect equipment, and ensure safe crane operations.

1)Sound and Light Alarm System
Purpose
Alerts nearby personnel during crane operation or in emergency situations

Provides visual and audible warnings during movement, overload, or fault detection
2)Limit Switches
Purpose
Prevent crane from exceeding safe travel, lift, or trolley movement boundaries, helping to:

Avoid over-lifting/over-lowering

Prevent collision with end stops

Protect mechanical structure and motor

10.Safety Devices

1)Overload Protection Device
Prevents lifting loads beyond the crane's rated capacity (10 tons)

Usually a load cell or strain gauge integrated with the control system

Can trigger alarms and stop lifting operation if overload detected

2)Limit Switches
Hoisting limit switches: Prevent hook from over-lifting or over-lowering

Trolley travel limit switches: Stop trolley at girder ends

Crane travel limit switches: Prevent crane over-travel on runway rails

3)Anti-Collision Device (optional for multiple cranes)
Uses sensors (ultrasonic, infrared) to prevent collisions with other cranes or obstacles

4)Emergency Stop (E-Stop)
Emergency push buttons located on crane and pendant controller

Instantly cuts power to motors and stops all movement

5)Sound and Light Alarm System
Audible alarms (buzzers or sirens) and flashing lights during crane operation

Warns nearby personnel of crane movement

6)Phase Failure and Phase Sequence Relay
Protects crane motors from damage due to incorrect power supply phases or power loss

7)Limit Torque or Torque Limiter (optional)
Prevents mechanical overload on gearbox or motor shafts by slipping at torque limit

11.Control Mode

1)Pendant Control
A wired handheld control device connected to the crane via cable.

Allows the operator to control all crane movements: lifting, trolley travel, and crane travel.

Features buttons or joysticks for precise control.

Common in smaller or medium-sized gantry cranes.

2)Wireless Remote Control
Provides operator freedom to move around the work area.

Controls all crane functions via radio signals.

Equipped with safety features like emergency stop buttons.

Ideal for larger workspaces or when visibility is better from different positions.

3)Cabin Control
Operator sits inside a cabin mounted on the crane.

Controls via joysticks, pedals, and buttons.

Offers excellent visibility and comfort for long operations.

Less common for mobile single girder gantry cranes due to their size but used in heavy-duty or specialized cranes.

4)Semi-Automatic / Automatic Control
Incorporates programmable logic controllers (PLCs) for automated sequences.

Used in specialized applications requiring repetitive or precise movements.

Can integrate with sensors for position feedback and safety interlocks.

5)Features of Control Systems
Multi-speed control for smooth operation.

Emergency stop and safety interlocks.

Overload and limit switch integration.

User-friendly interfaces for ease of operation.
