FIELD: radio engineering. ^ SUBSTANCE: hoisted-masted device that consists in lifting telescopic mast, cable lying mechanism performed by coil spring type, solid platform rigidly connected with lifting mast end step and rotating platform connected to solid platform by rotation axes. Cable laying device is located along longitudinal axis of lifting mast within transport size, solid and rotating platforms are ""-shaped, rotating platform has width not more transport size value in direction of its turn in relation to solid platform. Rotation axes are performed at side supports of platforms located in parallel to lifting mast longitudinal axis with shifts defined by specified dependences upon longitudinal axis as well as transverse axis of lifting mast. ^ EFFECT: increase of portability of hoisted-masted device by means of device arrangement optimisation in transportation position by choosing certain structural ratios. ^ 2 cl, 4 dwg |
