We are a proud manufacturer, exporter and supplier of Derrick Crane to our highly valued clients. It is used in industrial, construction and engineering applications. Heavy duty structural steel is used in its sturdy construction at our unit as per the set industrial norms and standards. Crane incorporates limit switches for rotation boom lowering lifting and load lowering and lifting to ensure accident free operation. Clients can avail it from us at highly pocket- friendly prices in the market.
These lifting machines have rational structures ie boom, central mast. They are made up for heavy duty structural steel frame work under which they duly relive the stress. The base of the central mast is fixed to the winch assembly which in turn rotates on specially designed Thrust Bearing anchored to the Central Foot. This rotation occurs by the means of bolts grouted in Concrete Foundation of rock. These Derrick Crane provide additional stability to the tower, as they are anchored in four locations, rather than just one like a normal crane. This also allows the free movement of cranes. It also allows the tower movement without sacrificing the stability.
The winch assembly consists of special crane duty motors which are connected to the helical speed reducers and reduction gear boxes dipped oil bath. The gear meshed are mated up to a grooved steel drum. The Electro hydraulic brakes are used to place the smooth lifting of weight. The winch assembly rotates on specially designed thrust bearing by mean of multiple step down gears which is built into the winch foot. The Wire rope is of 6 x 37 construction and 16mm in dia. The electric operations are controlled with Push Button Control unit, which is independent from the position of winch assembly. To ensure accident free operation, they also have limit Switches for Rotation Boom lowering lifting & load lowering/lifting.
