Strut channel, also known as Unistrut (a common brand name often used generically), has become a ubiquitous component in a wide range of industrial, commercial, and even residential applications. Its versatility stems from its simple yet robust design: a slotted, galvanized steel channel that allows for easy attachment of various components using nuts and bolts. One particularly important application of strut channel is its use in creating robust and adaptable track systems for trolleys, conveyors, and other moving equipment. This article will delve into the specifics of strut channel for track systems, covering various aspects from choosing the right channel to understanding the benefits and drawbacks of different approaches.
1. Understanding Strut Channel and its Properties:
Before diving into specific track applications, it's crucial to understand the fundamental characteristics of strut channel. The most common type is made of galvanized steel, offering excellent corrosion resistance. The slotted design is key to its versatility; the slots allow for easy attachment of various fittings, including brackets, clamps, and hangers. This eliminates the need for welding or complex fabrication techniques, significantly reducing installation time and cost. The standardized dimensions of strut channel ensure interchangeability across different manufacturers, although slight variations can exist. Common sizes vary in depth (height) and width, impacting its load-bearing capacity and overall rigidity. Choosing the appropriate size is crucial for the intended application, especially when considering the weight and movement of the trolley system.
2. SKTREX 5 Feet Length Strut Channel Trolley Track:
The SKTREX 5-foot length strut channel is a prime example of a readily available pre-fabricated track segment. This pre-cut length offers convenience for smaller projects or where specific track lengths are needed. The use of SKTREX, or similar pre-fabricated tracks, simplifies the installation process, requiring less on-site cutting and measurement. However, it's crucial to consider the overall project requirements. For larger installations, purchasing longer lengths of strut channel and cutting them on-site might be more cost-effective. The strength and load-bearing capacity of the SKTREX channel should be carefully assessed to ensure it can adequately support the intended trolley load and anticipated operational stresses. Furthermore, the quality of the galvanizing should be verified to ensure long-term durability, especially in environments with high humidity or exposure to corrosive elements.
3. Unistrut Trolley: A Better Approach to Overhead Mobility:
The term "Unistrut trolley" often refers to trolleys specifically designed to run along Unistrut channel tracks. These trolleys are typically equipped with wheels or rollers that precisely fit the channel's profile, ensuring smooth and reliable movement. The design of the trolley itself is crucial. Considerations include:
* Load Capacity: The trolley must be rated to handle the weight of the payload it will be carrying. Overloading can lead to premature wear and tear or even catastrophic failure.
* Wheel/Roller Type: Different wheel types offer varying degrees of smoothness, durability, and resistance to wear. Hardened steel wheels are commonly used for heavy-duty applications, while nylon or polyurethane wheels are preferred for quieter operation and reduced friction.
* Mounting Options: The method of attaching the payload to the trolley is critical. Secure and reliable mounting is essential to prevent accidental detachment and potential damage.
* Braking Mechanisms: Depending on the application, braking mechanisms may be necessary to control the movement of the trolley. These can range from simple friction brakes to more sophisticated systems.
