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.
