This application example describes a simple configuration for an overhead bridge crane (OHBC) which applies the SIMOCRANE solution for mid‑performance market.

Application example

The objective is to equip an overhead crane with necessary crane‑specific technology such as start‑pulse function for hoist, and masterswitch function for trolley (cross travel) and gantry (long travel). Furthermore, a sway damping is required for manual operation of trolley and gantry. In this way, it can relieve a crane operator and increases the crane productivity.

The following example shows a typical hardware configuration used in mid‑performance crane applications. It involves an overhead bridge crane (OHBC), controlled by using I/O signals. The SIMOCRANE Drive‑Based Technology provides crane‑specific functions, e.g. start‑pulse and load‑depending field‑weakening for hoist, and masterswitch and prelimit function for trolley and gantry. Furthermore, the SIMOCRANE Drive‑Based Sway Control can damp sway in manual operation for trolley and gantry, so both products meet the challenge of most applications in mid‑performance market.
