Insert gate arm onto adapter sleeve and secure with hardware provided. Provisions may include use of an “extended hold” to maintain the crossing gates down until the second train has arrived, as well as use of traffic signal control. Figure 7 1 2 3
Patent US3964704 Operating mechanism for railroad
When installing the model 95 exit gate mechanism, follow your railroad’s standard operating procedures.
In 1916, the american railway association, predecessor of the aar, formulated and adopted certain uniform standards for crossing warning systems.
Serves to energize the relay and the hold clear coils for gate operation. Models are available for standard highway vehicle crossing locations, sites with pedestrian sidewalks, and asts usa’s four quadrant gate system. National electric gate company is the leading manufacturer of crossing warning protection materials. I had a lot of requests to show how.
I made a follow up to my first video about the backyard railroad crossing video that i installed in the back of my house.
Fitted under a scalefour layout. The model 95 exit gate mechanism is designed to be installed with standard tools. Prevent backfeed of other gate mechanisms at a crossing when performing maintenance on one gate mechanism. Place ratchet wrench with 7/16inch socket over the hexagon shaft (brake side).
Generally, each crossing had four separate gates.
A newly designed hold clear with improved magnetics and mechanical latching is combined with the existing rugged 4 pole, series wound 12. Adjust and loosely tighten 5 locking bolts to align and secure gate arm. Miscellaneous format and editorial changes. The railroad crossing gate assembly 12 commonly used incorporates a gate arm 14 and support arms 16.
The motor shaft rotates in the opposite direction as the main shaft of the gate).
The operating mechanism of a railroad crossing gate employs a variable mechanical advantage connection to transmit force from the drive motor to the gate member to. All gate mechanisms are shipped with a tool kit (n46707001). Includes railroad signaling and grade crossing warning systems. Highway crossing gate mechanism, meet or exceed arema and american association of highway officials’ specifications.
A railroad crossing gate (20) is disclosed having a novel crossing arm (24) which includes a first longitudinal arm (26) member with a telescopically inserted second.
When commanded to raise or when power is lost, the gate raises to the clear or near vertical position. The gates were lowered and raised by means of cables or chains running through underground piping from the gatekeeper's crank base to each individual gate at the crossing. The exit gate is designed to raise the arm in a loss of power condition clearing the exit portion of the crossing. Where a railroad crossing has more than one through track, special consideration must be given to operation of the warning devices and traffic signal when a second train approaches following the passage of the first train.
The electronic gate monitor protects the mechanism from damage.
Once aligned, securely tighten the 5 locking bolt jam nuts. These standards included the painting of crossing gates. Install shear pin and cotter pin per figure 7a. Support arms 16 pivot about shaft 15 and about control assembly 18.
This kit includes allen wrenches for buffer and
