Technical specifications
Impact signal stability Adopting a precise mechanical structure and closed-loop control system ensuring high stability of the impact signal. Hammer status indication Display the status of 5 impact hammers through LED indicator lights ensure that the impact hammer talls normally Mains or battery powered This product is equipped with an internal battery pack (Nickel hydrogenate),which can help operators work without any cables. The battery automatically charges when connected to the main power supply. A fully charged battery can ensure 4 hours of continuous operation. Wireless remote control Adopting a 433MHz remote control, it has strong wall penetrating ability and a free field remote control distance of over 100 meters. Temperature control function Tapping machine is equipped with a motor overheat protection function to prevent damage to the motor caused by high temperature. Manual operation supported The Tapping machine can not only be remotely controlled through a remote control, but also supports manual control operation through the operation buttons on the front panel of the instrument |
