Double girder overhead cranes: - Ss. Cranes double girder cranes when heavy loads and wide spans are required, the ss. Cranes double girder travelling cranes show their strength. They consist of two torsion-free box girders. This makes them especially suitable for lifting and transporting loads over 10 t. Ss. Cranes double girder travelling cranes are available with load capacities upto 50 t. Articulated end carriage joints ensure positive contact of all four wheels with the track. The range of fixing arrangements allows the appropriate integration of ss. Cranes travelling cranes into new buildings as well as into existing buildings. Just as with all other types of ss. Cranes travelling cranes, the profiles of the main girder are optimally produced using computers so that maximum performance with a minimum of deadweight can be achieved. An advantage that has financial benfits. Standard features: - Design: - compact dimensions, low weight, easy to operate and easy to maintain, modular design with direct fits between components. Motors: - ss. Cranes uses sturdy cylindrical/conical rotor pole-changing motors with elegant continuous cast aluminium sections, integrated safety brakes insulation class f, ip54 protection. Gear boxes: - precision flat helical/spur gear units in light alloy housings with case-hardened gears, high-grade surface treatment and permanent oil/grease lubrication. Brakes: - single/dual-disc electromagnetic dc brakes featuring automatic braking on power failure. Environmentally sound brake linings designed for approx.1 million braking operations allow long maintenance intervals. Electrical panel: - modular design, covering a very wide operating range. The systems are designed for ease of installation and maintenance and reliable operation, with fuse less circuitry, ducted wiring and non-screwed terminals. Each drive group is equipped with a motor overload protection device to provide effective protection against inadmissible overloading. Painting: - every component & part is thoroughly scrubbed & painted with two coats of primer before assembly & two coats of synthetic enamel after testing Special features: - Limit switches: - to prevent over hoisting & over lowering of hook. Push button stations: - extra light, handy, easy to operate, aluminium, fabricated from extruded section. Soft starts: - electric/electronic soft start modules electrically coupled to the long travel drives to achieve jerk free, cushioned & smooth starts. Maintenance platform with hand railing: - easy, simple & safe maintenance of the crane extended partially or totally along the girder.
