In this automatic type, when when the revolving load is applied to the hydraulic motor in a particular direction, the oil in the hydraulic motor is confined (oil block) to produce braking force in the motor. But, in the case of revolving load in the reverse reverse direction, an oil block is impossible which will not permit to stop the hydraulic motor under the half way loading condition. Therefore, the controllable direction of the load is restricted.

The relief relief valv valve es on the the hydrau hydrauli lic c motor tor (co (control ntrol appa apparatus ratus valve valve bloc lock) are provided in order to t o pr pr otect tect the t he hydrauli hydraul i c mac machi hinery nery and equipment from over load. The reli relie ef valv valve es in the hydra hydrauli ulic c circ ir cuit are are provid provide ed to prote protec ct the the hydraul i c pump pump ove overr l oad.
CAUTION
OPERATION
Never rotate the adjusting screw of the valve which is set a proper oil pressure at our shop.
I n cases cases where the oi oi l pressure applie appli ed to the chambe chamberr [P] [P ] is i s bel bel ow the t he set set pressure, oi oi l pressure in each ach chambe chamberr of [P ] and [P 2] has the same level to maintain this condition. Therefore plunger is contacted with seat by force of spring [B] and pressure in chamber [P 1]. When the pressure in [P] chamber and in [P 2] chamber rises and the pressing force to the poppet becomes greater than the force of spring [A] (that is set pressure), the poppet is opened to release the oil from [P 2] to [R]. At this time, [P 2] chamber is connected to [P] chamber by orifice [A] and [B] ; thus, the oil passing through the orifices [A and B] is pressured and the pressure in [P 1] bec become omes lo l ower than t han the t he pressur pressure e in [P] [P ] to push up the t he plunger. The press pressure ure balanc alance betwee tween [P] and and [P1] is i s los l ostt and the plunge pl ungerr i s ope opened to release the oil from [P] to [R]. I n cases, cases, where the pressure pressur e i n [P] [P ] beco become mes s lower, the t he pressure pressure i n [P 2] also becomes lower to close the poppet and the pressure in [P] is same as the pressure in [P 1]. Then, Then, the plunge plunger is pre press sse ed back ack to the seat seat and and set set to the close lose positio position. n.

Then, operate each motion carefully at no load, confirming normal motion and sound. 6. The deck crane has a long pause and is always exposed to sea breezes and sea water, so electric parts are apt to cause some, troubles. Therefore check before operation, and regular intervals. 7. In case of cargo handling for powdered materials, fit the air filter(option) to air inlet side of the crane. 8. During maintenance maintenance,, refer to the
