The Shift Protection of Self Loading Mixer Machine

With concrete mixing and transporting in one, the self loading mixer machine is widely used for house building, road construction, slop protection, tunnel, ground consolidation,etc. At present, most self loading transit mixer don’t have shit protection device, therefore, the users are required to stop and shift gears.

To further improve working efficiency, there is an electronically controlled shift protection system, which is not only easy to install, but also can effectively avoid the harms caused by the speed shift of the gearbox.

The shift function of self loading mixer for sale

It uses a hydraulic gearbox with high and low gear options. The gearbox high and low gear ratios are 1.07 and 5.06 respectively. At high gear, the gearbox outputs high speed and low torque, which is used for high-speed transportation; at low gear, the gearbox outputs low speed and high torque, which is used for climbing.

The gearbox shifting principle is to switch the shifting hydraulic oil flow direction on the gearbox by operating the shift solenoid valve button in the cab to realize gear shifting. There is no gear shift protection in this shift system.

The electronically controlled shift protection system

The electronically controlled shift protection system adds speed sensors and signal converters to the original shift system. The speed sensor collects the speed at the output of the gearbox and transmits it to the signal converter. When the output speed of the rotational speed sensor is zero, the signal converter outputs a signal to the shift switch, and the shift switch operation is effective.

Electronic VS Hydraulic control shift protection system

The hydraulic control shift protection is mainly composed of a lock valve and a pressure reducing valve. When the service brake valve is under pressure, it indicates that the vehicle is braking, but the vehicle may not stop immediately at this time. If the driver changes gears at this time, the gearbox still has the risk of gearing.

In addition, The hydraulic control shift protection cost is relatively high, and the hydraulic pipeline is complicated. Through comparison, it can be concluded that the electronically controlled gearshift protection system is better.

As a self loading concrete mixer manufacturer, we can equip the equipment with the electrically controlled shift protection device. Welcome to leave message below to get a quote.
