RTG Crane Parts: Names, Functions, and Main Components

Введение

RTG crane parts include the gantry frame, hoisting system, trolley, spreader, rubber tires, drive units, electrical controls, and safety devices. Each component serves a specific function in container handling, from lifting and positioning containers to moving the crane across the yard. Correct part selection affects load capacity, operating performance, and maintenance requirements.

This article covers the main RTG crane parts, their functions, maintenance points, and factors to consider when selecting replacement components.

What Are the Main RTG Crane Parts?

Ан Козловой кран РТГ consists of structural, lifting, travel, electrical, and safety components. Each assembly supports a specific function, from carrying the load and positioning containers to moving the crane across the yard. The main RTG crane parts and their functions are listed below.

RTG Crane Part	Components	Function
Gantry Frame	Main girder, legs, cross beams, structural bracing	Supports the crane structure and lifting load. The main girder carries the trolley rails.
Hoisting System	Hoist motor, wire ropes, rope drum, sheaves, brakes	Raises and lowers containers.
Троллейбус	Trolley frame, wheels, drive motor, travel mechanism	Moves the suspended container across the gantry span.
Разбрасыватель	Headblock, twistlocks, lifting interface	Connects to and lifts containers. Available for 20 ft, 40 ft, and 45 ft containers, with single-lift or twin-lift configurations.
Rubber Tires and Travel Mechanism	Rubber tires, wheel assemblies, drive units	Moves the entire crane around the yard. Four-, eight-, or sixteen-wheel arrangements depend on crane design and ground pressure requirements.
Система рулевого управления	Steering drives, steering mechanism, control components	Changes travel direction. Steering configurations may support 0°–90° wheel rotation, depending on the model.
Система электропитания	Diesel generator, cable reel, or slide-wire supply	Supplies electrical power to the crane mechanisms.
Electrical Control System	PLC, sensors, control cabinet, variable-frequency drives	Controls lifting, trolley travel, crane travel, and steering functions.
Устройства безопасности	Limit switches, overload protection, anti-collision equipment, tire-pressure monitoring	Monitors operating conditions and prevents unsafe movements.

These RTG crane parts work together to handle containers and position the crane within the yard. Part specifications depend on lifting capacity, container size, travel requirements, ground conditions, and power configuration. For replacement parts, confirm the crane model, component name, part number, and technical specifications before ordering.

What Are the Structural Parts of an RTG Crane?

The structural parts of an RTG crane form the load-bearing framework for container lifting and yard travel. The main girder, gantry legs, lower crossbeams, and structural bracing support the trolley, hoisting system, and suspended load. Their dimensions and connections are designed around the crane’s rated capacity, span, stacking height, and operating conditions.

What Are the Main Lifting and Travel Components?

RTG crane lifting and travel components control container hoisting, trolley movement, load connection, and whole-crane travel. Each mechanism has its own components and operating function.

What Electrical and Safety Components Does an RTG Crane Have?

RTG crane electrical and safety components control motor operation, power distribution, operator commands, and protective functions. The configuration varies with the crane model, power system, and automation level.

Component	Function
Power Unit	Supplies electrical power to crane drives and auxiliary equipment.
Electrical Control Cabinet	Houses electrical control equipment, drive components, and protection devices.
PLC and Variable Frequency Drives (VFDs)	Execute control logic and regulate motor speed, acceleration, and deceleration.
Operator Cabin and Controls	Allow the operator to monitor crane status and control lifting, trolley travel, and crane movement.
Limit Switches and Load Monitoring	Detect travel limits and monitor lifting loads to support overload and movement protection.
Anti-Sway and Anti-Collision Devices	Reduce container sway or detect potential collisions where these functions are fitted.
Emergency Stop	Stops designated crane movements when an emergency occurs.

RTG Crane Power Supply Options

RTG cranes use different power arrangements according to yard infrastructure and operating requirements.

• Diesel generator set: Supplies onboard power and allows flexible travel without a fixed external power connection.
• Cable reel or slide-wire supply: Connects an electrified RTG to an external power source, reducing or eliminating onboard diesel generation during powered operation.
• Hybrid power system: Combines an engine-generator with energy storage or an electrical supply arrangement, depending on the design, to reduce fuel consumption.

The final electrical and safety configuration should follow the project technical specifications, yard conditions, and required operating functions.

Which RTG Crane Parts Require Regular Maintenance?

RTG crane maintenance focuses on components exposed to load, friction, vibration, and outdoor conditions. Inspection items include wire ropes, brakes, drive motors, tires, spreaders, and safety systems.

Wire Ropes and Sheaves: Check for broken wires, rope wear, deformation, lubrication condition, and sheave groove damage. Replace components that exceed the limits specified in the maintenance manual.

Brakes and Drive Motors: Inspect brake operation, motor temperature, abnormal noise, mounting bolts, and drive connections. Check for oil leaks around gearboxes where applicable.

Rubber Tires and Wheel Assemblies: Inspect tire wear, damage, wheel alignment, and fasteners. Check inflation pressure on pneumatic tires according to the specified range.

Spreader and Twistlocks: Check twistlock engagement, locking indicators, telescopic mechanisms where fitted, and structural connections. Test locking and release functions before operation.

Electrical and Safety Systems: Inspect power cables, connectors, sensors, limit switches, emergency stops, and overload protection. Test safety functions according to the manufacturer’s procedures.

Set inspection intervals according to the manufacturer’s manual, operating frequency, site conditions, and maintenance records. Record defects and repairs to track component wear.

How to Select RTG Crane Parts for Your Application

RTG crane parts selection requires accurate equipment data and technical specifications. Check the following details before ordering replacement parts or planning a system upgrade.

• Crane Identification: Confirm the RTG model, manufacturer, serial number, and production year.
• Part Specifications: Verify the part number, drawing reference, dimensions, materials, and original technical specifications.
• Operating Requirements: Check rated capacity, duty classification, and operating frequency.
• Electrical Parameters: Confirm motor power, gear ratio, supply voltage, and control interfaces.
• Tire and Steering Configuration: Verify tire size, wheel loads, wheel arrangement, and steering mechanism.
• Site and Service Requirements: Consider operating conditions, spare parts lead time, technical support, and after-sales service.

Mechanical dimensions, electrical parameters, and connection interfaces must match the existing equipment. Visual similarity or rated capacity alone is not sufficient for selecting a replacement part.
