The 5-ton overhead crane is a lifting device suitable for various warehouses and factories. In this article, I will introduce what a 5-ton overhead crane is, its pricing, technical specifications, features, and the pros and cons of this type of crane.
What is a 5-ton overhead crane?
An overhead crane is a type of equipment designed for lifting, lowering, and moving goods within factories and warehouses. With lifting capacities ranging from 1 to 500 tons (depending on the design and demand), and primarily operated by electric motors, overhead cranes are widely used in industrial manufacturing plants.
The overhead crane consists of two main movements: the horizontal movement of the crane trolley and the vertical movement of the hoist hook (or pulley) for lifting and lowering loads. The supporting structure for the hoist can be an I-beam, box girder, gantry beam, or suspension beam. The hoist can be either a chain hoist or a wire rope hoist.
A 5-ton overhead crane is a type of crane with a maximum lifting capacity of 5 tons. This type of crane is commonly used in smaller-sized workshops with a demand for lifting moderate loads, making it suitable for most workshops in Vietnam.
Types of overhead cranes
There are various types of 5-ton overhead cranes, depending on criteria such as functionality, drive mechanism, crane girder structure, and intended use. Some common types include:
By Functionality:
- General-purpose overhead cranes: Used for loading, unloading, moving, installing, and repairing machinery.
- Specialized overhead cranes: Employed in specific industries such as metallurgy, hydroelectric power, explosives, etc., with special load-handling devices and rigorous working conditions.
By Drive Mechanism:
- Manual drive: Operated manually using human force, such as hand-operated chain hoists or hand-operated winches.
- Electric drive: Powered by electric motors for efficient operation.
By Crane Girder Structure:
- Single-girder overhead crane: Utilizes a single main girder to suspend the hoist.
- Double-girder overhead crane: Features two main girders to support the hoist, often box girders or gantry girders.
- Suspension overhead crane: Lacks a main girder and has auxiliary beams suspended on overhead rails within the workshop.
By Intended Use:
- Various specialized types for specific applications, such as cargo handling, port cranes, metallurgical cranes, hydroelectric cranes, and explosive handling cranes, each equipped with special devices like grabs or magnets.
Construction
The construction of a 5-ton overhead crane may vary depending on the type and design. However, in general, it comprises the following main components:
- Lifting Mechanism: Used for lifting and lowering loads, typically a chain hoist or wire rope hoist. Chain hoists may be manual or electric, while wire rope hoists can be single-beam or double-beam.
- Traveling Mechanism: Responsible for the horizontal and vertical movement of the crane trolley and hoist. It often involves wheels driven by electric or manual power.
- Control Panel: Contains electrical devices for switching and protecting, such as contactors, circuit breakers, relays, etc. It facilitates the connection and disconnection of power to the crane’s motors and other components.
- Power Supply Lines: Provides electrical power to the crane, typically using methods like festoons, conductor bars, rails, or hanging cables.
- Remote Control Unit: Allows the operator to control the crane functions remotely, using wireless or wired remote control units.
Pros and Cons
Advantages:
- Precise and safe lifting of goods, saving time and labor.
- Modern design, superior features, and widespread applicability suitable for various workshops and projects.
- Reasonable cost, low maintenance expenses, and high durability.
Disadvantages:
- Limited lifting capacity, unable to handle excessively heavy or large loads.
- Requires sufficient installation space, including height, robust and stable overhead rails.
- Operation by skilled and experienced personnel is necessary, complying with safety regulations.
Quotation and Factors Affecting the Price of a 5-ton Overhead Crane
The price of an overhead crane is not fixed and varies depending on several factors. To obtain an accurate quotation for your crane, consider and determine the following factors:
- Span – Working Horizontal Length – Workshop Horizontal Length: The horizontal distance the crane must operate, including the working horizontal length and the size of the workshop, significantly influences the crane’s price.
- Lifting Height: The height at which the crane must lift and lower goods is a crucial factor. The crane needs the ability to lift to a height corresponding to your requirements.
- Rail Length – Working Length – Factory Length: The length of the rails the crane moves on, along with the size of the workshop, plays a role in determining the price.
- Type of Load – Frequency of Load Capacity Exceeding the Motor Load Capacity per Month: The type of load and frequency of crane usage also affect the crane’s design and price. If you regularly lift heavy loads, the crane design will differ.
- Construction Site, Installation Project Location: The installation location of the crane can impact the cost. Difficult or specialized installation sites may increase construction expenses.
In addition to these factors, the crane’s motor also plays a crucial role in determining the price. The use of a motor from South Korea, for example, may result in different pricing compared to motors from China, Japan, Germany, or the USA. Therefore, investors and contractors should carefully consider the motor as well.
Similarly, the working environment can also affect the price. Working under normal conditions may have a different price compared to working in special conditions such as explosive, clean rooms, or noisy environments.
