Electronic vehicle stability for MCS cranes

Item code: 11205

The Electronic vehicle stability system (EVS-H) is an intelligent and sophisticated stability safety system which actively monitors vehicle stability for MCS cranes. 

It is easy to operate, so easy that most often you, as the crane operator, will not notice it is active, unless you are in a situation that might become critical. 

The system includes all these conditions when operating: 

  • Load on the vehicle 
  • Load on the crane 
  • Speed 
  • Heel of the vehicle  

Therefore, you will get a warning before a situation becomes critical. This means that you can trust the system to automatically limit inappropriate movements and to stop at the designated limit. 

Use your load to reach further 

Working with truck-mounted cranes traditionally requires that the stabilizer beams are fully extended if they are to provide the necessary vehicle stability. 

Reality, however, tends to be different. Often, cranes have to work in cities with curbs, walls and a lot of obstacles that make it impossible to fully extend the stabilizer beams. This may also be the case in nature, where working in terrain with uneven and sloping surfaces can be challenging. 

With EVS you can optimize the working area of the crane without being limited by how far you can extend the stabilizer beams. 

The load on the truck body works like an anchor that gives a counterweight to the crane. The EVS system continuously calculates the total stability of the vehicle with the load integrated and actively includes the load on the vehicle. You can then utilize the maximum lifting capacity of the crane up to its limit – 360 degrees around the vehicle, within the stability available. 

Why choose EVS? 

Safety and flexibility 

The crane actively gets an optimized lifting capacity in the entire 360 degree working area – also in front of the vehicle, when there is load on the truck body. 

EVS provides dynamic operation, continuously monitoring the vehicle stability in relation to current conditions. 

EVS carries out ongoing calculations of the total stability of the vehicle, and because EVS also includes the load on the truck body and the total weight of the vehicle, it is possible to lift with optimized capacity in front of the vehicle, without having to worry about lack of stability. 

Concentrate on work 

EVS is intelligent and user-friendly, so it allows the operator to concentrate on the lifting task. It actively monitors what the operator intends to do and reacts continuously to ensure vehicle stability. 

EVS works together with the RCL safety system, which comes on all cranes. The RCL controller reads the operator's activation of the control levers before the crane begins to move and informs the crane on how to adapt movements and speed accordingly. In the EVS system it is the RCL that provides information about the conditions and load moment of the crane. 

This is the optimal interaction between the RCL and EVS; the RCL constantly monitors the current condition of the crane, and registers the movements of the crane, whereas EVS registers and monitors the condition of the vehicle on an ongoing basis and with extreme precision. 

Tried, tested, and approved 

EVS has been in successful operation on vehicles all over the world for more than 20 years. Today, most of our customers choose the EVS stability system for their crane. 

Stable crane operation 

Safety is important for everybody working with machines, cranes, or trucks. Still, you need the flexibility of maneuvering your truck-mounted crane freely, without having to waste too much time thinking about whether it is possible to perform the job in question. 

EVS will stop the crane at the limit of stability. When EVS registers that the crane has reached the safety limit, the system reduces the speed of the boom system. At 90% the RCL activates a signal. At 100% it stops the crane.  

Please note, EVS requires a crane installation on a truck equipped with air rubber wheels, where the wheels of the truck must be a part of the supporting area of the crane.
