hydraulic floor cranes


Our range of Hydraulic Floor cranes, offers an efficient low cost attentive to other material handling equipment. These cranes are strong, robust, sturdy and built to very high standards. Laden,these cranes are easily maneuverable and have a very small turning radius. they are ideal for loading,unloading and shifting of heavy loads.


General construction:

  • The crane structure consists of the chassis, vertical column, derrick (inner and outer boom) and the hydraulic cylinder assembly
  • All models above one ton capacity have a double column box frame made of steel pipes
  • The box frame can take heavy loads its wide bearing on the chassis effectively avoids twisting and damage to the crane under rough and unskilled handling
  • The advantage of this structure is that it diverts the resultant force to the center of the chassis thereby greatly reducing the possibility of imbalance about the longitudinal center of the chassis
  • The derrick consisting of the inner and outer boom is suitably reinforced by the bow structure, welded on to the outer boom for better distribution of forces
  • The inner boom has six locking points, and telescopes into the outer boom. it is fitted with a 360,rotating, forged steel hook
  • The wide bearing of the derrick, on the double column frame reduces the effect of to-provisional forces within the frame
  • The chassis is fitted on four wheels
  • Two wheels are fitted on rigid castors and two are either fitted on swivel castors or into a steering assembly
  • Cast iron wheels are provided as standard. However rubber tread wheels, may be fitted on request
  • The steering assembly has a combination of heavy duty thrust bearing and toper roller bearings
  • The rigid castors wheels are fitted with wheel locks to prevent movement when transfer of load takes pales
  • The chassis is a rugged all steel electrically welded structure. It is this member which differentiates one model from another Two types of constructions are offered, i e ('U' frame type and 'G' frame type

'U' Frame:

  • Here the chassis is 'U' shaped, and the job to be lifted is accommodated within the frame itself
  • The equipment is useful for loading and unloading jobs into trucks and other areas, where the legs can easily slide under obstructions
  • The advantage of this equipment is that, being shorter in length it has a small turning radius and no counterweights are required for balancing moments
