The 555 provides the lifting capacity of Manitowoc’s popular Model 3900 and 3900W cranes plus easier mobilisation, faster set up, and Manitowoc’s patented EPIC controls with the CAN-Bus technology. The Model 555 was introduced to replace more than 1, 000 Model 3900s and 4000s now in use, intended as a replacement for the discontinued 4000 series cranes.
