Maz floor level crane

The Maz floor level crane is used to perform three main functions: Open, hold, close the pressure. Designs may differ, but the principle of operation is built the same.

How does the faucet work?

  1. It is built into the pneumatic system, responsible for the position of the floor, adapting to external circumstances.
  2. The changes cause air to be drawn in or out, keeping the floor balanced.
  3. Together with it, the control of the levers functions, which often poisons the air, creating inconvenience. It should be inspected and maintained periodically.
  4. The crane allows you to adjust the floor level depending on the road surface, hiding irregularities.

This is a fairly simple device, familiar to many truck drivers. The car aligns its position relative to the horizon, responding to an increase or decrease in load.

Which is better: mechanical or electric crane?

Before you decide which Crane floor level Maz to buy, you need to compare the main characteristics.

Mechanical crane

Advantages

  • Low price.

Disadvantages

  • Can not quickly change the level in an emergency.
  • Significant air consumption.
  • Numerous articulations of tubes.
  • Requires calibration.

Electric crane

Advantages

  • Can urgently change the level.
  • Allows you to switch to manual mode.
  • Calibration takes place using a special device.
  • Many craftsmen have adapted to replace expensive components with cheap analogues.

Disadvantages

  • A large number of additional details.
  • High price.

Perhaps, the Maz electric floor level crane has a significant advantage over its mechanical counterpart, except for the price.

Renovations

Any equipment breaks down for any reason. It is important to know the structure of the device and understand what leads to a decrease in functionality.

For example, the floor level tap Maz 5440 can freeze (like any other model). The solution to the problem is quite elementary: remove the condensate and check the eccentric. For a full repair, some experienced drivers recommend a complete replacement of both sensors and calibration.

Much less often there is a control panel or valve block. For example, it is necessary to diagnose the crane floor level Maz 6430. If the indicators of the air suspension do not light up when the ignition is turned on, then first of all check the fuses.

Calibration

The procedure assumes that the unit will remember the readings of the instruments at various positions of the body. The floor level of the MAZ 5440 changes when driving on the road surface, softening irregularities, so it is very important for the integrity of the load and for the comfort of the driver to set the optimal height. In addition, the height of the suspension directly affects the brakes and suspension.

As a result, a couple of tricks from truckers.

  • The pressure gauge attached to the spring terminal correctly shows the axle load.
  • The pressure difference in the axles leads to uneven loading of the truck axle.

It is very important to monitor all vehicle systems to ensure a safe ride.
