The paper provides description of an approach to calculate main parameters of energy-power block of geokhod computing the hydraulic motor capacity of each end user. The paper determines the effect of geokhod dimensions on capacity consumption by main geokhod systems. The shares of capacity consumed in each geokhod system are calculated.

Abstract. The issue of designing drives, which provide low frequency (max. 1 rotation per minute) rotation with a big moment (min 1 MN m) of large technical bodies utilized in restricted spaces, is a complex and contradictory one. The drives of geokhod propeller, rotor actuators of tunneling machines with overload protection, as well as actuators of other machinery meeting aforementioned requirements are examples of such machines. The paper considers mathematical model developed by the authors which determines the relation of design factors of transmission tooled with hydraulic cylinders to kinematic parameters of output element movement. The paper also provides description of methods to determine pumping unit efficiency for rotary transmission tooled with hydraulic cylinders.
