In its basic function, the DCBS is a stepless chain hoist based on the DCS series. It masters the usual tasks of this hoist: the operator activates the D-Grip Servo operating handle and the load with a maximum weight of 160 kilograms is raised or lowered using an electric motor.

According to the manufacturer, however, what sets the DCBS apart from other chain hoists is the integrated balancer function, which is familiar from the Demag E-Balancer D-BE. It enables loads to be guided without operating the control pendant. The operator simply moves the load to the desired height with little force and can position it more precisely with both hands because he does not have to take the "detour" via the control panel.

By pressing a switch, or automatically if set accordingly, the DCBS switches between the two operating modes "handle guidance" and "load guidance" and enables intuitive load guidance. The hoist is equipped with sensitive sensors for this purpose: Using a pressure sensor, the hand force of the operator is detected, in the handle guide, and this is converted to control the lifting movement. This eliminates the need for the operator to press buttons to control the hoist.

An integrated load sensor detects weight and possible weight fluctuations and derives the desired direction of movement and speed from this in the load guidance system. This allows the operator to guide the load into the desired position with both hands. In joining mode, which is particularly suitable for joining components horizontally, any possible swinging of the load is prevented and converted into a gentle pendulum movement. This enables components to be joined, avoids possible damage caused by the parts hitting each other and therefore also increases the speed of assembly.

The fourth operating mode of the DCBS is the load pick-up mode. This function is useful when changing tools or removing parts from sensitive fixtures or test stands. The balancer can be set so that it only lifts until a preset force is reached. It therefore enables the lifting and pretensioning of the load handling attachment - with the result that the load can be removed from a device without sagging or tilting upwards. At the same time, the machine or device is protected against excessive forces. All operating modes are linked to additional protection and safety functions such as adjustable load or speed limits.

Combined with the Demag KBK light crane system, the DCBS opens up mobility for horizontal load transport. It can travel in the KBK profile rails on suspension cranes in single-girder design or in system suspension tracks and slewing jib cranes. as
