Operation And Use Explain Of Putzmeister Concrete Pump Truck With VOLVO

August 8, 2022

In order to ensure the safety of the concrete pump truck operation and avoid personal or equipment accidents, the following safety operation procedures must be strictly observed.

Safety Inspection before operation

Before work or preparing to work, the driver should check the following points and make sure that:

（1）The machine is placed on even, compact ground, which satisfies the loading requirements.

（2）The working area is sufficient for extending the outriggers and telescopic boom.

（3）The surrounding area is free from dangerous objects such as electric cables, explosive & combustible materials, etc.

（4）The switches & levers used to control boom, outrigger and pump are in non-working position.

Note:Emergency button should be released, otherwise, the machine.

（5）The meters for engine speed, water temperature, engine oil pressure, etc, are in normal working range.

（6）The pressure gauges (control pressure, accumulator pressure) of pumping system and suction & returning line are in normal working range.

（7）Joint of each boom section should be greased.

（8）There is not any serious wear in the concrete pipe and the thickness satisfies conveying requirements.

（9）Other parts of the vehicle satisfy performance requirements.

Operation of Outriggers And Boom

（1）Open the mechanical locks of all outriggers.

（2）Put the selected switch “ Panel / Remote” on the control panel to “Panel” position.

（3）Make sure that nobody except the operator is in the working area of the machine, then control the outrigger levers on both sides of the machine according to the indication on the lever.

（4）Extend the front and rear outriggers successively, until they swing to Max. limit position.

（5）Using the proper pad according to ground conditions, lower two front outriggers until the front wheels leave the ground, then lower the two rear outriggers until the rear wheels leave the ground（The ground clearance should be about 50 mm）.

（6）Adjust the height of front & rear outriggers, so that the whole machine is level. （ Max.inclination must be less than 3°）.

（7）Finally, confirm that all the outrigger control levers are returned to the neutral position. When pumping is finished, before retracting outriggers, please ensure that the boom is placed on the boom collar properly, then retract outriggers in reverse sequence of the extending procedures. Carefully operate the lever before the outriggers are fully retracted or fully extended to avoid impaction.

Operation Of The Boom

（1) USE AND MAINTENANCE MANUAL Rotate the “Panel/Remote” switch on the control panel to “Remote” position.

（2）Use horn to give warning. (horn should be used intermittently during boom moving.)

（3）Open boom successively according to the indication on remoter. For differe machines, boom opening sequences may vary according to different folding types. Basic folding types are “R” type and “Z” type. Extending procedures are as follows.
