The era of manually driven cranes has past. Now, crane manufacturers now provide top performance mechanically an electrically with the aid of intelligent drive solutions from NORD gear.
In crane applications, calm movement, high start-up torque and a high level of positional accuracy are all critical specifications. Additionally, traction and lift drives must also be adjusted to crane types, such as the single-arm hook or a gantry crane used in shipbuilding. When using cranes indoors, space consideration also plays an important role. NORD offers a variety of solutions to meet all of these requirements.
Wind, precipitation, temperature fluctuations are just some of the factors that mother nature uses to push envelope for crane and gear drive design. NORD provides a range of products and options to combat these forces. NORD drives are operationally reliable from -25 °F to 100 °F, and offer a number of protective features and coatings for outdoor use. NORD also offers synchronous carriage drives to provide reliable, high power levels for the crane industry.

NORD carriage drives ensure extraordinary straight-running precisions. For example, the shipyard portal crane GOLIATH, has a positional accuracy of 0.08” to 0.20”, even under the most extreme conditions. State of the art frequency inverters like the NORD SK 700E is used to ensure this positional precision. The SK 700E allows soft start-up, and has defined dynamic braking to guarantee GOLIATH will take loads exactly to there intended locations.
NORD’s reducers, motors and frequency inverters all have advantageous design features for the crane industry. With torque capacities up to 885,000 lb-in and 200 HP, NORD is sure to have the single source drive solution for all crane applications.
