Operating conditions during test Mounting of equipment If the crane is equipped with outriggers, they shall be fully extended shall be levelled on its pads in mid position of possible support height Test under load

The mobile crane to be tested shall be presented in its standard described by the manufacturer. The engine power considered for determination noise limit is the nominal power of the engine used for crane motion. be equipped with its maximum permitted counterweight mounted structure

Before carrying out any measurement, the engine and the hydraulic mobile crane shall be brought to their normal working temperature instruction of the manufacturer and all relevant safety-related procedures the instruction handbook shall be carried out If the mobile crane is equipped with several engines, the engine crane’s function shall be run. The carrier engine shall be turned off If the engine of the mobile crane is fitted with a ventilator, it shall test. If the ventilator can be operated at several speeds, the test shall with the ventilator running at the highest speed

The mobile crane shall be measured under the following three ((a) ((a) to (d)) conditions:

For all working conditions the following shall apply: - engine speed at 3/4 of maximum speed specified for crane mode with a tolerance of ± 2% - acceleration and deceleration at the maximum value without movements of the load or the hook block - motions at maximum possible speed as given in the instruction under the conditions given

(a) Hoisting

The mobile crane shall be loaded with a load which creates 50% of rope force. The test consists of hoisting of the load and the immediately lowering to the starting position. The length of the boom shall be chosen full test lasts 15 to 20 seconds

(b) Slewing With the boom adjusted to an angle of 40º to 50º to the horizontal and the upper carriage shall be slewed 90º to the left immediately followed back to the starting position. The jib shall be at its minimum length. The period shall be the time needed to carry out the working cycle Derricking starts with raising the short jib from the lowest working position followed by the lowering of the jib to its original position. The shall be executed without load. The duration of the test shall be at least 20

Telescoping (if applicable) adjusted to an angle of 40º to 50º to the horizontal without load and retracted, the telescoping cylinder for the first section only shall be together with the first section to its full length and immediately retracted the first section observation/determination of resulting sound power level if more than condition is used resulting sound power level is calculated by: telescoping is applicable log (0.4 x 100.1LWAa + 0.25 x 100.1LWAb + 0.25 x 100.1LWAc + 0.1 x telescoping is not applicable log (0.4 x 100.1LWAa + 0.3 x 100.1LWAb + 0.3 x 100.1LWAc)

MOBILE WASTE CONTAINERS

emission standard ISO 3744:2000

Reflecting surface of concrete or non-porous asphalt Laboratory room which provides a free field over a reflecting plane Environmental correction K2A Measurement in the open air

Measurement indoors of the constant , determined in accordance with Annex A to MSA K 2A 3744:2000, shall be < 2.0 dB, in which case shall be disregarded. K2A Measurement surface/number of microphone positions/measuring distance

Hemisphere/six microphone positions according to Part A item 5/r = 3m conditions during test measurements shall be carried out with an empty container

Free shutting down of the lid along the container body To minimise his influence on the measurements, the operator shall back side of the container (hinge side). The lid shall be released by prevent warping during its fall The measurement is carried out during the following cycle, repeated - initially, the lid is raised vertically - the lid is released forward, if possible without giving an the operator at the back of the container, unmoving until - after complete shutting, the lid is raised to its initial position Note: If necessary the operator can move temporarily to raise the lid.

Test No 2: Complete opening of the lid To minimise his influence on the measurements, the operator shall back side of the container (hinge side) for the four-wheel containers, side of the container (between microphone position 10 and microphone for the two-wheel containers. The lid shall be released by its middle possible to its middle. To prevent any moving of the container, wheels shall be locked during the two-wheel containers, and to prevent any bounce of the container, can maintain it by placing his hand on the top rim

The measurement is carried out during the following cycle: - initially, the lid is opened horizontally - the lid is released without giving an impulse - after complete opening, and before a possible rebond, the its initial position Test No 3: Rolling of the container over an artificial irregular track For this test, an artificial test track, simulating irregular ground is track consists of two parallel strips of steel mesh (6 m long and 400 fastened in the reflecting plane approximately every 20 cm. The distance between the two strips is adapted according to the type in order to allow the wheels to roll all over the whole length of mounting conditions shall ensure a flat surface. If necessary, the track the ground with resilient material to avoid emission of parasitic noise Note: Every strip can be composed of several 400 mm wide elements together An example of adequate track is given in Figures 39.1 and 39.2

The operator is situated at the lid hinge side The measurement is carried out while the operator draws the container artificial track, with a constant speed of approximately 1 m/s, between B (4.24 m distance - see Figure 39.3) when the wheel axle, for a 2-wheel or the first wheel axle for a 4-wheel container, reaches point A or procedure is repeated three times in each direction During the test, for a 2-wheel container, the angle between the container track shall be 45º. For a 4-wheel container, the operator shall ensure contact of all the wheels with the track.

Period(s) of observation/determination of resulting sound power level one operating condition is used and 2: Free shutting down of the lid along the container body and opening of the lid the measurements are carried out simultaneously at the six microphone Otherwise, the sound levels measured at each microphone position will be increasing order and the sound power levels are calculated by values at each microphone position according to their row

A-weighted single-event sound pressure level is measured for each of the 20 the 20 openings of the lid at each measurement point. The sound power shutting and opening are calculated from the quadratic mean of the LWA values among those obtained Rolling the container over on artificial irregular track of observation shall be equal to the duration necessary to cover the T between point A and point B on the track. power level rolling is equal to the mean of six values differing by L WA If this criterion is not fulfilled with six measurements, the cycle is as necessary resulting sound power level is calculated by: log 1/ (100.1LWA shutting + 100.1LWA opening + 100.1LWA rolling)
