Product Description
75T Overhead Travelling Crane Euro Hoist With Welded Box Girders 3 Phase
Description of Overhead Travelling Crane
Overhead cranes are used to move extremely heavy or bulky loads through the overhead space in an industrial facility. Their use conserves space on the floor and leaves aisles clear, unlike a forklift or other material lifting device. Overhead cranes lift, lower and move a load horizontally, directed by an operator either manually or with wireless controls. They tend to have low maintenance costs comparatively and have the most lifting height for higher vertical stacking and efficient use of space. Operator safety is ensured due to lack of obstacles in the way to run into.
Silence Industries designs and manufactures overhead cranes for all types of applications, from simple work stations to sophisticated custom lifting systems.

Detailed Configuration of Suspension Overhead Travelling Crane
Types of Runways
Runway System using Sister Columns & Tied Back to Building
Building is able to support lateral loads from runway system.
Our standard tieback is a bolted flexible tieback design vs. rigid tiebacks.
Flexible tiebacks allow the tie back to flex.
The runway deflects and vibrates as the crane travels.
Rigid tieback welds are put under repeated fatigue loading.
The bolted flexible tieback is highly recommended for larger capacity systems.
Longitudinal bracing is Standard on all of Silence Crane systems.
Bridge Cranes overhead crane Ace Industries Crane Manufacturing
Runway on Haunches
Haunches or Secondary Columns mount directly on building columns.
Building design must be able to support crane loadings.
Bridge Cranes overhead crane Silence Industries Crane Manufacturing
Free Standing Runway System
Used if building cannot support any loading and footers may be required.
Requires more steel to fabricate vs. a system that can be tied back.
Silence uses Moment Columns vs. A Frame Columns.
Moment Columns use the foundation to support and stabilize the system.
No bracing is needed, more steel in the column than a system tied to building.
A-Frame columns may be less expensive, but take up more space.
Longitudinal bracing is standard on all Silence Crane systems.
