Fast, safe and efficient loading thanks to Safety Jack
Many managers are aware of the need for safety measures in the loading zone. However, trucks are still not adequately secured before loading and unloading - against rolling away, tipping over or excessive deflection. Three "small" measures with the help of a wedge and Safety Jack can help.

Safety measures do not always have to be "big" measures, such as the introduction of automatic loading or an all-integrating docking station. In day-to-day business, the smaller elements that can contribute to greater safety in the loading zone are also crucial. They too can be significantly improved.
Against rolling away
The need for safety measures to prevent trucks from rolling away during loading or unloading has long been a high priority for most responsible parties. However, if implemented in accordance with the regulations - i.e. the truck driver secures the truck and the loader then checks it - this is time-consuming and error-prone without technical support. This process can be supported with monitored wheel chocks such as the Arnold electric chock. This is either wired or uses radio sensors to check whether the wedge has been activated before loading begins. This means that the loader can always see the status from the door via an indicator light without having to go outside.
Against tipping over
The risk of tipping is still too rarely taken into account. As a result, there are still numerous loading situations in which a forklift truck is used to drive onto parked semi-trailers and nothing is done to prevent the risk of tipping. The employers' liability insurance associations stipulate that securing must be implemented in the event of dangerous forces in the longitudinal direction, as the resulting accidents are at least as dangerous as those caused by a truck rolling away.
With the so-called safety jacks, a wide range of solutions have long been available to solve this task quickly and easily. Positioned at the front, they support the trailer to prevent it from tipping over. They can simply be moved manually on rollers and can therefore be used by any trained person without any additional aids.

While all models prevent the semi-trailer from tipping over, they usually differ in their design. Inexpensive solutions are usually painted and only equipped with a simple spindle. If longevity is important, a galvanized version should be chosen instead, as they do not immediately start to rust if the paint is damaged. The wider the support chosen, the more the trailer can be prevented from swaying sideways.
Against the spring deflection
The canopies of older loading systems are often too low for the increasingly high trucks. When a forklift truck drives in, they go deep into the often very soft suspension and then bounce particularly high when the forklift truck leaves - and depending on the design, both the vehicle and the canopy are damaged. In many places, the deeper deflection also leads to the problem that the loading bridge cannot bridge as low as the truck deflects. This creates a prohibited tripping hazard between the truck and the bridge. To prevent this, there are aids for the lateral rear support - these safety jacks are pushed laterally under the side members of the vehicle using a long handle and prevent the truck from deflecting too much.
All these measures help to avoid expensive investments and at the same time significantly increase safety during loading.
