INTRODUCTION
The NLH double girder crane has all the advantages of the HD single girder crane. And it has a greater lifting capacity than a single girder crane. The trolley is walking along the two main beams and the operation is more stable. The hook is between the two main beams, so the lifting height is higher. End beam adopts hinge connection to avoid single wheel suspension. There are maintenance platforms on both sides to facilitate the maintenance of motor and trolley maintenance. If you use it frequently, the larger NLH bridge crane is your best choice. Customers can choose the pendent line with press button, wireless remote control or cabin.
