Crane Shed

Crane System

For buildings that require a crane system, DPEB supplies the column or rafer brackets. The crane runway beams for top-running and under huge crane systems will be supplied by DPEB. For mono-rail crane systems the runway beam is supplied by the crane supplier. The customer needs to supply complete crane system details, data and supplier name, for the accurae design and estimaiton of all crane supporting buildings.

Crane Shed

The most common type of overhead crane in PEB'S is the overhead Top Running Crane. Buildings with Top Running Cranes are normally supplied with column crane runway beams and crane brackets. Indepondent crane columns are supplied only when crane capacities are high or id specified by a Customer.

Buildings with Underhung Crane are supplied with crane runway beams, rafter brackets, lateral kicker angles and vertical bracings.

Buildings with Monorail Cranes are supplied with rafter brackets, lateral kicker angles and vertical bracings. The monorail beam is normally designed and supplied by the monorail supplier.

Buildings with Jib Cranes are supplied with cap channels (welded to column flange) and bracings.

Monorail Beams

These are the cheapest form of overhead cranes. Teir limitation is that their hoists carry loads in one direction only. The monorail beam is normally supplied by the supplier of the Monorail system.

Crane Rails

Crane rails are excluded from our supply. in order for us to provide most economical design for crane runway beams and for the supporting building clements, the Customer must provide us with the following crane data.

  • Location of cranes in the buildings
  • Travel length ofcranes
  • C.L to C.L. distance of crane rails
  • Crane hook heightLocation of cranes in the buildings
  • static wheel loads
  • Vertical and horizonatal clearances
  • wheel base & bumper distances of end carriages
  • Type of crane operations (cab or pendant)
  • Type of crane duty cycle (full capacity lifts per hour)
  • No. of cranes operation in single bay.

Jib Cranes

These are suitable for the movement of materials within a limited area that is determined by the cantilevered length of the hook. The maximum economical crane boom distance is normally 3 m.
