Actuators serve surprising purposes

A linear actuator from LINAK can be used almost anywhere that requires linear movement. Actuators have many uses, particularly in industry where some of them serve a rather different purpose. On this page, we have highlighted some of the applications where an actuator has been used as a smart solution to some unusual challenges. Prepare to be surprised – and inspired!

Smart brick cutter

All bricklayers face a common problem – cutting a brick is usually a manual and very tough job. But the company Smart Cutter has come to their rescue with an application for cutting bricks. The machine uses two LA30 actuators from LINAK.

Many bricklayers struggle with shoulder and collarbone pain from manually cutting bricks. The man behind Smart Cutter spotted a need to develop an electric cutter to improve the working environment for bricklayers. By using a Smart Cutter, bricklayers avoid putting as much strain on their bodies when cutting bricks. This means fewer injuries and improved efficiency.

The brick cutter
The cutter cuts a brick using two parallel LA30 actuators and a TR-EM-339 third-party control with a special program – all supplied by LINAK. The cutter is intelligent in that it remembers the size of the actual type of stone and retracts a couple of millimeters more than this position after each cut. The cut is made with the simple touch of a button. The cutter can be manually adjusted if the stone type changes.

Cleaning robot for pigsties

Cleaning out a pigsty is a dirty job. WP Production, a sub-contractor of Washpower A/S, has produced a cleaning robot with an LA12 actuator from LINAK.

You may think that cleaning a pigsty is a pointless task. But this is far from the case! For pig production all over the world, keeping the sties clean is a high priority, as well as whenever the pigs are moved. The cleaning process has always been a manual job using high-pressure washers. But thanks to the new cleaning robot, this is no longer the case. The result is a much easier job and a higher standard of cleaning – to the benefit of pigs and employees alike.

The robot
WP Production and Washpower A/S are behind the cleaning robot. It works by entering the pigsty and washing down all the surfaces with a powerful water jet. An LA12 IC actuator from LINAK is used on each robot to move the spray nozzle, depending on where the water jet needs to aim. WP Production has created its own PLC control.

Truck Mounted Attenuators for emergency situations

When a road accident occurs, it is essential to quickly and effectively close off all affected lanes. A job that ScanLED solves using a Truck Mounted Attenuator (TMA), which uses LINAK actuators to lower two blocking wings.

In emergency situations such as road accidents, dropped freight or emergency roadwork, it is essential to quickly close one or more lanes. In such situations, a so-called Truck Mounted Attenuator or TMA is a useful tool. The attenuator is fitted to the back of a truck, which is then parked in front of the area that needs to be closed. Despite the total weight of 10 tons, the attenuator protects both those working in front of the truck, but also any motorists who fail to notice the barrier, as it is possible to survive a collision with the attenuator.

The Truck Mounted Attentuator
ScanLED adapts the TMA for optimal use in emergency situations. Typically, a TMA is the first to arrive at the scene, and it must be able to close several lanes. That is why ScanLED uses LA36 actuators from LINAK along with TR-EM-288 third-party controls to lower the wings on one or both sides of the TMA. ScanLED uses actuators instead of, for example, hydraulics, to increase safety, as the forces of the actuators can be adjusted so that the wings do not pose a clamping hazard. The wings do not protect from a collision like the TMA, but they are able to effectively indicate that the road is closed until an extra TMA arrives at the scene. With both wings lowered, it is possible to block 7 meters, corresponding to two entire lanes.

ScanLED is also unique for using an extra actuator and a control to tilt the top of the trailer, which allows for driving under bridges and through tunnels.
