#CMT# #/CMT# The control has a two 24 volt direct current electromagnet coils (4, 5), and compressed air piston controlled by 24 volt direct current electronic switches (2, 3), where the switches are push buttons or rocker buttons. The switches include a 2 ampere fuse (1). One electronic switch is provided in a driver's cab of a concrete mixing lorry and another electronic switch is provided in the rear of the lorry. #CMT#USE : #/CMT# Electro-pneumatic control for controlling a hydraulic pump on a concrete mixing lorry. #CMT#ADVANTAGE : #/CMT# The arrangement of the control facilitates precise controlling of the concrete mixing, ensures easy installation and operation, and reduces maintenance operations and wear out of parts. The control does not freeze, as the control is provided inside the lorry and is inexpensive to fabricate. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of an electro-pneumatic control.'(Drawing includes non-English language text)' 1 : Fuse 2, 3 : Electronic switches 4, 5 : Electromagnet coils. |
