Hot Dip Galvanized Cranes

Powered Rotation Hydraulic Lift Stacker Crane

7 ton capacity top running double box girder hydraulic lift stacker crane with 48" load centers as measured from the face of the 8 foot long forks. 

Top Running Double Girder Crane

Shown here is a CMAA Class "D" 40 ton capacity, 71'-4" span box girder bridge. The two outside hoists have a 20 ton capacity and the hoist in the center has a capacity of 40 ton. Trolleys are synchronized using Variable Frequency Drives. Hoists are synchronized using Closed Loop Flux Vector drives. Primary means of control is Radio, with backup traveling push button station.

Under Running Double Girder Crane

This 10 ton capacity bridge features a top running dual girder ultra-low profile trolley hoist. Riding under one of the bridge girders is a 2 ton capacity "javelin". The javelin hoist is used to project product under the runway beam and into the adjacent bay. Controls include collision avoidance systems to limit bridge travel when the javelin is extended between building columns.
