Right equipment from right manufactures is highly important for major operations and dangerous environments. Log handing, steel production, mining, petrochemical processing, nuclear power generation, and other functions are easily carried out by industries using overhead cranes like double girder. All material handling requirements are effectively handled by these critical material handling equipments. Wide choices and varieties are available when it comes to selecting the right kind of double girder cranes. Outstandingly designed, rugged, superb quality procedure and heavy duty cranes are staying above comparison for performance, safety and robustness. Customers can pick from many industrial cranes that are designed for their particular requirements according to capital investment they can make. Total cost of ownership and peace of mind is ensured with double girder machines and lifting equipments. These devices are being used for space-related issues and heavy weight material movement. Major element included on an overhead crane is a traveling base that fits over traveling rail on both sides. End carriage on the either sides come with a geared motor and wheel base for crane movement. Welded steel box or structural tub that is built with end trucks are usually used for construction in order to get ultimate rigidity. Top girder works as the agent for side movement of the trolley and hoist. Top girder maximizes the height of the lift and minimizes the headroom. Trolley and hoist configuration have special motors and gear assemblies. Hoist is considered as the real working area of a crane that can be customized according to the clearance, duty, speed and lifting requirements. Apart from this, double girder machines also have a drive arrangement on the top girder for sideways movement. These machines have potential to carry weights across the width and length of the construction or manufacturing location and transfer them at the machining destination. Double girder lifting machines come with special and flexible frequency drive for smooth start-up and stop, exact positioning, and controlled accelerations. Operators can control the transferring and dipping in of the machine according to the location of the construction process. Major kinds of overhead cranes are fitted with ratio operations that allow operators to make adjustments in order to stand anywhere and check with the crane safety. Actually, these cranes are offered in 4 basic configurations, and each one provides exceptional solutions and qualities for material handling. In an overhead crane or top running bridge, Crane Bridge moves on the upper part of rails. And, it is making movement through the bottom flange of the runway beam when it comes to under running crane. A beam structure is used to support the bottom flange. Double girder machines are powered with 2 end trucks, trolley hoist, and bride girders that travel on the top of the rails of bridge girders. In most cases, crane manufacturers and companies offer after-sale services and replacement facilities. However, customers need to make sure about those facilities before making a purchase.
