2000 Kgs Stationary Gantry Cranes

 

A 2000 kg stationary gantry crane is a fixed-position lifting system designed for handling and moving heavy loads up to 2,000 kilograms (2 metric tons). Unlike mobile gantry cranes, the stationary variant is securely anchored to a specific location, offering enhanced stability and precision for repetitive lifting operations in confined or designated work areas.

These cranes typically consist of a sturdy horizontal beam (girder) supported by two vertical legs, which are bolted or fixed to the floor or foundation. The crane's hoist and trolley travel along the beam to lift and move loads across the span. This configuration is ideal for environments where consistent lifting is required over a fixed area, such as workshops, assembly lines, warehouses, and maintenance bays.

Key Features:

Lifting capacity: 2000 kg (2 tons)

Fixed installation for high stability and reliability

Manual or electric hoist and trolley options

Customizable span and height to suit operational needs

Ideal for indoor applications or covered workspaces with limited mobility requirements

Stationary gantry cranes are valued for their cost-effectiveness, ease of installation, and ability to improve workflow efficiency by reducing manual handling and lifting fatigue. With fewer moving parts compared to mobile or overhead crane systems, they also offer low maintenance and high durability.

4.Crane travelling mechanism

1) Working principle

The wheels are attached to axles or wheel blocks that help in distributing the load evenly across the crane.The drive motor activates the wheels through a system of gears and reducers, converting the motor's rotational force into torque.The wheels, mounted on the frame of the crane, roll along the rails on which the gantry structure is placed.The power to the wheels is transmitted via a combination of chains, belts, or direct coupling depending on the design of the crane.The crane traveling mechanism of a Double Main Girder Gantry Crane involves synchronized wheel and motor systems that enable the crane to move along its designated rails, with additional features ensuring safe, balanced, and efficient operation.

2) Functions of the crane operating mechanism

Horizontal movement: The primary function of the crane travelling mechanism is to move the entire crane structure along the rails or tracks that are placed on the ground or the sides of the installation area.

Support and Stability:The travelling mechanism ensures the crane is securely supported on the rails or tracks. It helps distribute the weight of the crane evenly and provides stability during movement.

Power Transmission:The crane travelling mechanism is powered by electric motors that drive wheels or gear systems. These motors convert electrical energy into mechanical energy, propelling the crane forward or backward.

Load Distribution:The travelling mechanism helps distribute the load evenly across the crane's wheels and tracks, preventing damage and ensuring the durability of the crane and its components.

5.Trolley travelling mechanism

1) Structural composition

Trolley frame: The frame is typically made of high-strength steel to support the load and withstand the stresses during operation.

Wheel set: The trolley is equipped with wheels that run on the rails of the main girder. These wheels are often made of hardened steel or cast steel to ensure durability and wear resistance.

Drive device: Electric motors are commonly used to provide the necessary power for the trolley's movement A gearbox is used to control the speed and torque of the trolley's movement.Couplings connect the motor to the gearbox and ensure smooth transmission of power to the wheels.

.

2) Function of the trolley operating mechanism

Horizontal Movement: The primary function of the trolley traveling mechanism is to move the trolley horizontally across the length of the main girders. This movement allows the crane to position the hoist over a desired load location.

Load Handling: By moving along the main girders, the trolley helps in positioning the hoist system accurately above the load, which is necessary for lifting and transferring goods efficiently.

Power Transmission: The traveling mechanism typically uses electric motors and gear systems to provide the necessary torque and speed for the trolley's movement. The motors can be either AC or DC, depending on the design and requirements of the crane.

Rails and Wheels: The trolley runs on rails that are mounted on the main girders. The wheels on the trolley are designed to travel along these rails, ensuring smooth and stable movement. The wheels may be fitted with flanges to prevent lateral movement and maintain alignment.

Safety Mechanisms: The traveling mechanism is equipped with safety features such as limit switches, braking systems, and overload sensors to prevent accidents and ensure the safe operation of the crane.

6.Crane wheel

1) Function of wheels

Load Bearing: In a double main girder gantry crane, each wheel supports a significant portion of the crane's load. The wheels must be engineered to handle both the static and dynamic loads imposed during lifting operations.

Material Handling and Safety: The design of crane wheels must ensure safe operation, especially when handling heavy or oversized loads. The wheels should be engineered to minimize noise and vibrations during operation.

Rail Compatibility: Crane wheels are designed to run on specific rail types (e.g., flat or curved tracks). The size and shape of the wheel flange must match the rail profile to ensure proper fit and smooth operation.

2) Design requirements

Material and Design: Crane wheels are typically made of high-strength steel or cast iron to withstand the heavy loads and stresses associated with lifting and transporting materials. The design often includes a flange to ensure proper alignment and prevent the wheels from derailing off the tracks.

7.Crane Hook

The crane hook of a double main girder gantry crane is an essential component used for lifting and transporting heavy loads.

Design and Structure

Material: Typically made of high-strength steel to withstand heavy loads and provide durability.

Shape: The hook often has a C-shape or a pointed end for securely holding lifting slings or chains.

Size and Capacity: It is designed to match the lifting capacity of the crane, which can range from a few tons to several hundred tons for large industrial cranes.

Types of Hooks

Single Hook: Common in standard applications, used for lifting a load from a single point.

Double Hook: Utilized when a more balanced load is needed, often in double main girder designs for higher lifting capacities.

Crab Hook: In gantry cranes, the hook may be mounted on a trolley or crab that runs along the girders.

Motor

The motor of a double main girder gantry crane is an essential component that provides the power necessary for lifting, traveling, and sometimes rotating the crane's hoist or trolley system.The motor's power rating must match the crane's capacity and the load it needs to lift. Typically, these motors range from a few kilowatts up to hundreds of kilowatts, depending on the lifting and traveling requirements.

Motors can be equipped with variable frequency drives (VFDs) for smooth speed adjustments and energy savings.Safety and control systems like overload protection, braking systems, and emergency stops are incorporated for safe operation.

The motor should be compatible with the electrical supply available at the operating site, which can vary (e.g., 380V/50Hz, 480V/60Hz).The motor in a double main girder gantry crane is used for operations such as lifting heavy loads, moving the crane along the tracks (longitudinal travel), and sometimes lateral movement (cross travel) of the hoist or trolley.

Sound and light alarm system & limit switch

1) Sound and light alarm system

A double main girder gantry crane, commonly used in heavy-duty operations, often incorporates safety mechanisms like sound and light alarm systems to ensure safe operations.

Sound Alarm (Horns/Buzzers): These are typically loud, audible devices that emit a distinctive sound to alert people in and around the working area. The sound level is designed to be high enough to be heard over operational noise.

Light Alarm (Flashing Lights/Beacons): Visual signals, such as flashing lights or rotating beacons, help alert personnel visually, especially in noisy environments where sound alarms may be insufficient.

2) Limit switch

A limit switch on a Double Main Girder Gantry Crane is a safety device used to prevent the crane from moving beyond a designated range. This ensures the protection of both the crane and its surroundings, as well as any loads being lifted.

Key Functions of Limit Switches:

Position Control: The limit switch helps monitor and control the position of the crane's trolley, hoist, and gantry to prevent over-travel and collisions.

Safety Shutdown: If the crane moves past its allowed limits, the limit switch signals the control system to stop the motor and prevent damage or hazardous situations.

Emergency Stop: It can act as an emergency cutoff to shut down the crane when it approaches the limits of its track or rail, preventing it from derailing or causing accidents.

Types of Limit Switches Used:

Mechanical Limit Switches: Activated by physical contact, often using a lever or cam that triggers the switch when moved by the crane's motion.

Electronic Limit Switches: Use sensors (e.g., inductive, capacitive, or optical sensors) for non-contact detection, providing higher durability and reducing wear and tear.

Rotary Limit Switches: Typically used in applications where rotational motion needs to be monitored, such as in hoists.

Linear Limit Switches: Used for applications where linear travel is monitored, commonly found in the movement of the trolley.
