Statlock Stabilization devices can have various names, such as ‘statlock’, ‘rigging’ and ‘slings.’ They are always connected to the machine they are designed for, most often an operator or a spindle. Usually four types of statlocks are used in industrial machines: straight, carabiner, snap link and swivel link. Later on in this post you’ll learn more about how each type of statlock works and its best use case.
You will encounter statlock devices in many industrial machines. Industrial machines are the ones that contain an operator, specifically a CNC machine or a laser machine. This guide is particularly focused on these two types of machines, because they contain operators that use a statlock device with a load cell design. There is no need for a device like this in specialty machines such as wire cutting machines or turret punch presses.
Statlock devices are vital for CNC and laser machine operators to do their job properly and safely. An operator needs to use some type of rigging to help them align the part and machine properly before starting the job or when making last minute adjustments during it. The way a statlock device works also makes it possible for CNC and laser machine operators to start their jobs faster and with full control of the machine.
1. Statlocks Are Designed For Specific Applications
The type of device you have will determine how you rig your load cell. There are four different kinds of statlocks on the market — straight, carabiner, snap link and swivel link. One kind is not better than the other. It’s just a matter of preference and application. You will need one or more types depending on the size of the machine and your personal preference. Depending on your machine, there might be limited space behind the load cell for rigging; this makes some types better than others for certain applications (e.g., if you have limited space behind the load cell).
2. Straight Slings Are For Small Machines
Small machines are a rarity these days, so it’s likely that you won’t have one of those anymore. A small machine is an industrial machine with a linear axis. These machines can be quite heavy and sometimes they’re not meant to be touched by operators while running the job. As such, they seldom use statlocks as an operator is not likely to grab them, let alone throw them around when helping the operator start and stop the job.
3. Carabiner Slings Are Best For Line-Thru Machines
The carabiner sling is the most common type of statlock. It’s used in everyday applications besides other types also. It is attached to a chain that stretches behind the load cell and connects to the machine via screws and caps (or hooks). This means it can be attached to a terminal point of the machine, like a motor or spindle, or even behind a plate, like some laser machine operator’s statlocks are.
Unlike other types of statlocks that are attached to a link or rod that runs across the load cell, there is no interference between this link and the load cell. The carabiner sling is the most recommended choice for laser machines, because it’s one of the only types that can be attached behind a plate.
4. Snap Links Are Best For Machines With A Small Load Cell Area
The snap link statlock is one of the oldest types on the market. It can link to a chain that runs across the load cell, or directly behind it. You will often see this type of statlock attached to other links to increase strength when used with a chain or rope. The snap link statlock is also used as a load switch in some machines when there is no room for other types of statlocks behind the load cell. A load switch (also called a load cell switch) is a mechanical device that usually has two chains. It’s used to help the machine start and stop the job, but it can also be used to detect the maximum force the machine is able to apply (a so-called tare function).
5. Swivel Links Are Best For Laser Machines
The swivel link statlock is another type of statlock that you might find behind laser machines with CNC capabilities. It looks similar to a carabiner, but its link is shaped differently so that the part does not get stuck in it when it gets pulled back. Its link looks more like a circle than a rectangle. This circular-like link rotates freely, and it can be used as a load switch when you need one. The swivel link design is also less likely to break under pressure.
