P350 Operation Manual 10
Wheels and tires
The P354 uses the small and medium wheel sets. These can also be ‘doubled-up’ to improve traction in larger pipes.
It’s recommended range is between 4” and 15” (60mm to 305mm). The small wheels are 62mm / 2.5” diameter and
the medium wheels are 110mm / 4.3” diameter.
The P356 uses small, medium and large wheels, which can also be ‘doubled-up’ to improve traction. This allows it’s
use for centralized survey of pipe diameters between 6” and 36” (150mm and 900mm). Above this size you may have
issues with lighting, view or driving ability. The small and medium wheels come with hard or soft tire material options
to suit different grip requirements. The large wheels are 170mm / 6.7” in diameter.
NOTE: although it will work electrically and mechanically, we do not recommend use of a PTZ camera on a P354
Crawler due to the weight and size of the camera
Connecting wheels and tires
Figure 2.2 demonstrates how to attach wheels and tires to the P354 and P356 crawlers (62mm and 110mm only).
The inner hub is located on the crawler’s body. Place the wheel on the inner hub and secure in place using the outer
hub clamp.
NOTE: Ensure the wheel screws fit firmly to the crawler.

NOTE: Item 6 “V-seals” prevent debris ingress into the crawler seals on the medium and large wheel sets. It is
beneficial to check and replace these at regular intervals or ask our service teams to do so. 4x part 04/B1525510
