A derrick crane is a fixed type of crane having a center coloumn, tie members and a jib Rational structure i.e., boom, Central mast and rafters are made out of Heavy duty structural steel frame work duly stress relived. The base of central mast is fixed to the winch assembly which in turn rotates on specially designed Thrust Bearing anchored to the Central Foot by means of bolts grouted in Concrete Foundation of rock. The winch assembly comprises of special crane duty motor connected to helical speed reducers and reduction gear box dipped oil bath and gear meshed are coupled up to a grooved steel drum. Electro hydraulic brakes are used to central the smooth lifting of weight. The winch assembly rotates on specially designed thrust bearing by mean of multiple steps down gears built into the winch foot. Electric operations are controlled with Push Button Control Unit Independent from the position of winch assembly. Limit Switches for Rotation Boom lowering lifting & load lowering and lifting are provided to ensure accident free operation. We manufacture the Derrick Crane following the industry laid parameters and the demands of our clients.
