Single-Girder Bridge Cranes

Single-Girder cranes are lighter than double-girders. This kind of cranes is suitable for light operations, middle-heavy operations, but also for heavy operations. We manufacture standard single-girder cranes up to 25000 kg with variable span up to sizes given by transporting capabilities of driveways to the place of installation. Girders can be made of box constructions or standard tube-shaped profiles.

Single-girder bridge cranes are designed to create equilibrium between the price and performance. Easy handling and safety at work are our priorities, so if you are looking for the highest level of reliability and performance and the lowest costs for maintenance you are at the right place.

Technical information

  • Maximum load bearing capacity up to: 25000 kg
  • Colour: of a steel construction is RAL 1007, components in the original colour
  • Span: limited by transporting capabilities
  • Hight of lift: up to 15 m
  • Speed of crane trolley drive: normally up to 40 m/min, smooth moving
  • Speed of hoist trolley drive: normally up to 20 m/min, smooth moving
  • Speed of lift: up to 19,2 [m/min]
  • Lift of hooks: two-speed (the main lift and micro lift)

  • We supply standard chain hoists LIFTKET or rope hoists STREET
  • Controlling via hanging button-controllers or via radio remote controllers
  • Power supply of crane: via cable trolleys, via closed trolleys covered by plastic or via energy chains
  • Crane setting: outside and inside


  • Each crane is projected to measure according to customer´s requirements to be adapted to a place and shed´s conditions (or to open space) and still work effectively
  • Lay out of crane weight into two end carriages guarantees safe handling with the load
  • Long-term operation without any incidents and with minimal costs for maintenance
  • Remote control
  • The possibility to place the crane both inside and outside
  • In contrast to double-girder cranes, single-girder cranes are cheaper

Accessories and options

  • In case of remote control, the crane could be equipped with emergency control via the hanging button-controller which could move along the whole crane independently of crab trolley drive or it could be connected to the main switchboard of the crane via connector
  • Crane is equipped with two hoists working either independently or in tandem (at the same time) using just one controller
  • Weighing of transported load with an output to a crane display, to a controller display or to PC
  • Anti-collisional systems in case of several cranes being on one railway
  • Version with a slewing beam, with a grab or with a magnet
