A remote level gauge is provided through the rubber plug to detect the liquid level in the tank truck. The remote level gauge has an interlocking function, and the interlocking action is to stop the ammonia pump.

[0008] The rubber plug is connected to the exhaust pipe in front of the check valve by a metal hose.

[0009] The bottom of the loading crane pipe is sealed with a concave steel plate with a hole in the center. Three 40mm×50mm rectangular holes are evenly opened around the bottom side of the crane pipe. Their function is to evenly distribute the loaded materials to the surroundings to prevent splashing.

[0010] The clamp is made of 30408 ​​material, has a diameter of 110-120 mm, and a thickness of 5-8 mm.

[0011] The bolt is M16×160 and made of 30408 ​​material.
