MACTON® Freight Rail Products PORTABLE JACKS - HEAVY DUTY LOCOMOTIVE AND RAIL CAR MAINTENANCE EQUIPMENT * * * * * * EASE OF PORTABILITY SAFETY CONSCIOUS RUGGED CONSTRUCTION SIMPLE OPERATION & MAINTENANCE 5 YEAR WARRANTY COMPETITIVE PRICING Macton portable jacks deliver maximum floor space flexibility, transforming any location that can support substantial floor loading into a potential maintenance or repair area. Not only can a portable system be moved anywhere in the shop, but the individual jacking units in the system can also be independently positioned to adjust easily to a variety of support points on a railcar. Macton portable locomotive jacks operate individually or as a set for lifting locomotives or transit cars. When used as a set, the jacks are synchronized to assure safety and uniform travel among the jacks at all times. The electrically powered, machine screw drive system in the Macton jack is continuously self-locking to provide maximum security during lift operation. Locomotive jacks are complete with rubber-tired wheels and are easily moved and positioned under the vehicle. Jacks are available in capacities from 10 to 50 tons per jack with lifting heights to suit customer requirements. Control systems utilize a programmable controller for integration of safety interlocks and warning systems. Electrical features include upper and lower limit switches, load sensors on the jacking pad, motion control, group, pair and individual operation, and remote control operation.
