Henan Mine Heavy duty electric cabin control gantry crane 250t for outdoor
Product description of gantry crane 250t
Heavy gantry crane is mainly composed of mast, crane trolley, trolley operating mechanism, driver's cab and electrical control system. The main beam adopts the double-beam derailment form, and the overarm can be divided into A type and U type according to user's requirements. The operating mode is closed driver's cab, the seat is adjustable, the bottom plate has insulation pad, the window glass is toughened glass, can be equipped with cooling and heating air conditioning, buzzer, intercom and other items according to user requirements. There are two power supply modes: cable tray and high-altitude sliding wire. According to the customer's working environment and working level using special steel and design, to meet the customer's large tonnage lifting needs, can be customized according to customer requirements of lifting speed, running speed, can be customized installation can only operate monitoring system, so that the crane safety can only efficiently complete the work requirements.

The gantry crane is also the gantry crane working level A: it reflects the working characteristics of the crane in two aspects: load status and utilization. The division of work levels is determined by the utilization level U and load status Q of the crane. They are divided into eight levels from A1 to A8. The working level of the crane, that is, the working level of the metal structure, is determined by the lifting mechanism, and is divided into A1-A8 level. If compared with the crane work type specified by China, it is roughly equivalent to: A1-A4-light; A5-A6- Medium; A7-heavy, A8-special heavy.
