divided into two major types. They are:
1. Single Girder Cranes
2. double girder cranes
Single Girder cranes:
Single girder cranes are designed to cover
a wide range of modern industrial demands, providing excellent
value for money with no compromise on performance. Amsak's single
girder crane has reduced wheel loads, saving costs on new support
structures and increased lifting capacities on existing structures.
Amsak cranes offer various crane beam to end carriage constructions
to ensure optimum use of headroom available. Hoists are offered
as standard in low headroom format running on the bottom flange
of the beam.
Double Girder cranes:
Double girder cranes give a better height of lift in a given
headroom as the hook travels between the beams. They are available
in higher capacities than single girder and for heavy duty applications
they can be supplied with open winch hoists.
Normally double girder cranes have 25 tonnes capacity and also
in higher capacities. One simple advantage of the double girder
design is the possibility to fit a walkway to the crane which gives
maintenance access to many critical parts of the crane and often
to overhead lighting etc.
