30 (1) One near each side on each end of car, not less than 24 nor more than 30 inches above centre line of coupler, except as provided above, when tread of end ladder is an end handhold.

(2) Side handholds shall be not less than 24 nor more than 30 inches above centre line of coupler, except as provided above, where tread of ladder is a handhold.

Tail rotor drive shafts, flexible couplings, bearings, vibration dampers and bearing hangers

5.3. It must also be possible to couple and uncouple ball couplings when the longitudinal axis of the ball coupling in relation to the centre line of the coupling ball and mounting:

For steering equipment in which the steering forces are provided solely or partly by the muscular effort of the driver the steering control includes all parts up to the point where the steering effort is transformed by mechanical, hydraulic or electrical means; 1.3.2. Steering transmission includes all parts of the steering equipment which are the means of transmitting the steering forces between the steering control and the steered wheels; it includes all parts down from the point where the steering control effort is transformed by mechanical, hydraulic or electrical means; 1.3.3. Steered wheels means the wheels the alignment of whic ...[+++]h may be altered directly or indirectly in relation to the longitudinal axis the vehicle in order to determine the direction of movement of the vehicle (The steered wheels include the axis around which they are rotated in order to determine the direction of movement of the vehicle); 1.3.4. Energy supply includes those parts of the steering equipment which provide it with energy, control the energy and where appropriate, process and store it.

The constant of an output drive is the value of the volume represented by a complete turn of the shaft of this drive ; this value is calculated by multiplying the value of the volume represented by a complete turn of the test element by the transmission ratio of the index counter to this shaft.
