产品简介：
电动葫芦门式起重机，是遵循GB/T3811，起重机设计规范，及JB/T5663，电动葫芦门式起重机，等国家和行业标准设计,制造的起重机。起重机以CD，MD，等形式的钢丝绳电动葫芦作为起升机构，通过起重机吊钩的上下移动及起重机的前后移动组合形成立体的作业空间，实现对起吊物品的移动，翻转等作业。广泛用于码头，货场，仓库，建筑工地等露天及室内场地等工 况。
电动葫芦门式起重机主要结构由门架，电动葫芦，电气装置，大小车运行机构组成；在作业时小车运行速度不大于40m/min,大车运行在地面按钮装置操纵时运行速度不大于45m/min，在地面遥控操纵时运行速度不大于50m/min;司机室操纵时运行速度不大于63m/min。 使用性能 起重机的工作及别是按照起重机的使用等级及载荷状态确定的；
电动葫芦门式起重机在静载试验时，能承受1.25倍的试验载荷，且在载荷位于悬臂极限位置时，能保证另一端的车轮不出现负轮压；主梁的上拱度大于等于0.7S/1000,有效悬臂处的上翘度大于等于0.7L1/350。
Henan mine crane co., LTD. Product introduction:
Electric hoist gantry crane, is follow GB/T3811, crane design specification, and JB/T5663, electric hoist gantry crane, national and industry standards such as design, manufacture of the crane.Crane with CD, MD, etc in the form of a wire rope electric hoist as lifting mechanism, through the crane hook and crane to move up and down before and after the mobile combination form three-dimensional space, realize to the movement of the lifting goods, flip, etc.Widely used in wharf, freight yard, warehouse, construction sites and other outdoor and indoor and field work Conditions.
Electric hoist gantry crane main structure by the door frame, electric hoist, electric installation, large car running institutions;In the job when the car speed is not more than 40 m/min, cart running in the floor button device control is not more than 45 m/min running speed, on the ground remote control is not more than 50 m/min running speed;Cab manipulation is not more than 63 m/min running speed.Use the crane performance of work and is in accordance with the crane and load state of the use of grade;
Electric hoist gantry crane in the static load test, able to withstand 1.25 times the test load, and when the load is located in the cantilever limit position, can guarantee the wheel at the other end of the wheel is not negative pressure;On the girder of camber is greater than or equal to 0.7 S / 1000, become warped on effective cantilever of greater than or equal to 0.7 L1/350.
