122-mm Howitzer had beendesigned based on fullynew scheme – the howitzerhas three side plates andchassis located on the upperSide.While putting the howitzerinto combat condition oneof three side plates is fullyunmovable and other twocould be moved (pulled) for120° relating to that one).Such construction provideshigh stability while firingand full round firings withoutmoving the side plates.Transportation of the Howitzercould be made by any3 tons vehicle. The constructionof the Howitzeralso allows easy transportationon the aircraft and easydropping from aircraft onthe special platform.To the present days, Armiesof more then 50 countriesin the world use such Howitzer.

working days, per year 250 days
working shifts 2
duration of one working shift 8 hours
Installation of production line for 122 mm Ammunition includes the following stages,
which will be fulfilled by our Company:
1. Supply of main and supporting technological equipment for manufacturing of cases of
122 mm artillery shells.
2. Supply of main and supporting technological equipment for equipping of cases of 122
mm artillery shells.
3. Supply of main and supporting technological equipment for manufacturing of cartridges
for 122 mm artillery shells.
4. Supply of other supporting and engineering equipment.
5. Supply of special accessories and fixtures.
6. Supply of spare parts, required for one year exploitation.
7. Supply of engineering and designing documentation for manufacturing of 122 mm artillery
shells:
• technical description and manuals of main and supporting equipment;
• technical specifications;
• construction documentation for preparation of building project on deployment
of the equipment for manufacturing and equipping of cases for artillery shells;
• technology of manufacturing and equipping of cases for artillery
shells and manufacturing of cartridges for artillery shells;
• technical requirements for buildings, facilities, energy carriers, ventilation
systems and communication means.
8. Fulfillment of contract supervision and commissioning works.
9. Training of technical specialists at the Customer’s country.
On the requirnment of the Customer, the Production Line could be easily converted
into the line for manufacturing of Ammunition of caliber from 70 mm up to 152
mm, just by replacing of some of main and supporting fixtures.
Functions
The following personnel are required to undertake D 30 howitzer overhaul to the required level:
Expertise levels
In order to achieve this trainees will require the following basic skill sets:
Organization of Training
Whilst it is appreciated that the aim is to carry out as much training as possible on an OTJ basis considerations of practicability and safety dictate that some degree of theoretical instruction will be required to bring trainees to the level of competence necessary for them to function effectively on the overhaul line.
In terms of basic qualifications the major requirements for trainees are as follows
For those in this category it is proposed to organize trainees into two groups of 12 individuals and each group will undertake a maximum of four hours of theoretical training or six hours of practical training on any one day. Practical training will commence after trainees have demonstrated an understanding of the theoretical elements.
Theory Training
This will take place in a classroom environment equipped with tables, seating, white-board, and overhead projector.
Documentation will be provided on overhaul and operation of D30 supplemented by illustrative wall posters.
Training will be provided by a combination of short lectures and classroom discussion. Tests on theoretical knowledge will be made on a regular basis to determine candidate’s suitability to proceed to the practical stage.
Practical Training
Practical training will take place on the established overhaul line, the content and structure of which is dealt with in the main proposal.
After completion of the initial five howitzers under close supervision, each group of trainees will undergo practical examination carrying out an independent overhaul of a further three howitzers.
For this purpose an examining committee will be formed, which in addition to the instructor for each discipline will also include customer representatives.
Technicians who successfully pass this practical examination will be nominated as artillery mechanical engineer level 3.
With further on the job training it is anticipated that able individuals will progress to level 6.
Trainees will also take part in post overhaul testing of the howitzer at the nominated firing range in the presence of customer representatives/mentors.
Lathe operators and welders will require additional practical training, which can be provided during the overhaul process. (OTJ)
Training Session Content
Each training session lasts 50 minutes, and the total comprises 292 hours, split between process practical training 212 hours and theoretical 80 hours.
Module 1 – 12 hours
Module 2- Overhaul Fundamentals – 48 hours
Module 3- Process Practical Training – 212 hours
Module 4 – Quality Enhancement and Training of Trainers – 20 hours
