STREET JIB CRANES - Slewing Jib Cranes Street slewing jib cranes are available in a wide range of standard formats in capacities from 125kg to 6300kg. Larger specially designed options are available on request. Street Crane offer two formats of jib crane, the pillar or post-mounted jib and the wall or column mounted. Each of these may be equipped with chain hoists or wire rope hoists with the additional options of electric travel and electric slewing gear. The jib arm may be under or over braced to maximise height of lift or travel. Post-mounted jibs can be constructed to provide a slewing angle 360°. Fixed jibs and monorail solutions may be appropriate for other applications.
