The barrel consists of the soul, the ass mainly with unášecím the naked eye, the physical accessibility of airports of the bridge and screwed the barrel. The conclusion is a horizontal wedge. A special feature is the two-piece cradle, which is in the unfolding of the transport is decomposed into two parts. The front part of the cradle to form a whole with the main and BVZ. In the cradle is saved BVZ, which consists of a liquid of the brake (adjusted to three lengths of the zákluzu in connection with the náměrem) and vzduchokapalinového vratníku. Thus in one war the united BVZ with the regulator of the length of the zákluzu enjoyed the Škoda already on their pre-war cannons, for example, already in the howitzer H1, but also with howitzers H3, which is exposed in the VTM in Lešany. Along the sides of the cradle for lafetovým the shield are placed two spring vyvažovače. Top gun-carriage is to be stored pivotovým the pin on your carrier. The elevation is given by hand-wheels located along the sides of the upper carriage and odměrové řididlo it is only on the left side. The lower gun-carriage is formed an upper carriage, where they are fastened lafetová shoulders with a firm rydly and tučky. The remedy is stored kyvně the pin in the carrier of the upper carriage. Howitzer is only partially odpérována using zpruhových bumpers and only when transporting in a single unit. Disk wheels have the tires stuffed mushroom lined. Wheeled brake drum, čelisťová controlled by two independent hand levers on both sides of the howitzer. Protective lafetový shield is made from 5mm neprostřelitelného of sheet metal and fastened on the top was coming. On the left kolébkovém of the pin are restrained miřidla, which forms an independent t-bar sight vz. 38S with periskopickým panoramic dělovým telescope PG and sight for direct fire vz. 52 with binoculars 3 x 8°.

Howitzer could be transported in one unit zapřažená directly behind the towing vehicle or decomposed into two units of two zapřažených in a horse dvojspřeží. Ammunition and equipment are transporting in one unit on the towing vehicle or on the mountain káře drawn dvojspřežím.

For houfnici was envisaged with the soviet auto ammunition for 122mm houfnici vz. 38, mainly grenades gusty, dýmový and průpalný.
