ENDO has recently released a new model, the ERM series retractor, designed to suspend various tools and equipment using the spring tension as a driving force for the other application. It is an ideal tool for used in automation, machine builders and manufacturing, and process lines.
The difference between retractors and spring balancers is that retractors are designed to retract the cable when no force is applied.
This means that an amount of downward force must be constantly applied to keep the suspended object at its extended position. The torque output of the rewind spring increases as the cable is extended and retracting the suspended object to the uppermost adjusted position when released. The ratchet stopper device can be turned on or off according to requirements. The retractor’s tension can be adjusted with just a hex-key and features a convenient and detachable top hook. Installation is also flexible, coming equipped with four mounting holes to attach to other devices.
Retractors can also be used to hold electric screwdrivers. They can pull it down, use the screwdriver to manufacture the component. When they’re done, they can just let it go and it will move out of the way.
They can then pull down a different screwdriver, for example one with a socket head fitting or hex head fitting. You don’t have a bench that’s cluttered with tools, they can just pull them down as they need them.
The ERM Series Retractor supersedes an older product.
One of the main benefits is it merges two of its products. It used to be they’d have one of the spring retractors had a ratchet mechanism and one without. So now they’ve made it so that it’s just the one product, and you have a switch where you can turn the ratchet mechanism on.
They also found that a lot of the spring retractors were used in applications where a hook suspension is no ideal, so they’ve made it so you can bolt it directly to a frame.
It might be you have a machining centre with a safety gate. You could use the spring retractor there to lift it up or to pull it down so you can then operate the machine.
KITO PWB’s spring retractors are available for applications ranging from 1 to 20 kilograms and is designed for a long life – backed with a 12-month warranty.
By using this piece of equipment, manufacturers can enable tasks at production and assembly stations to become increasingly efficient, allowing staff to save time and work at faster paces.
