Use caution boom is very important in the construction of which preferred to choose the ground flat surface, and surface soil should not be too soft, if the operation is not smooth pavement construction sites, then use an equal area of ??wood or other things put flat in order to maintain a balance of concrete placing booms. In the boom time job, to use steel and oil wire rack strong and tensioning device, generally like tubing plant in Kyushu and other boom manufacturers do not provide these. Mainly with shelf stable steel boom, and then the oil silk strong hove tight. Once again to check the presence of sodium and calcium matrix lubricant is injected into each lubrication point, in order to maintain the normal use of the boom. Like electric boom, when in use in order to maintain balance boom must be in the latter two counterweight box added five hundred to eight hundred kilograms of weight to maintain their balance, boom installation is completed to a comprehensive examination under base and cable wind rope whether both safe and reliable. Kyushu pump Pipe Manufacturing Co., after ten years of manufacture of the boom have a very comprehensive insights on the material when washed with fresh water through the pump delivery tube ten minutes, in the concrete slowly into soil material feeding, injection The water slowly reduced to an appropriate amount of time can be a normal construction work. Kyushu tubing plant technical staff to remind you that the manual boom in the use of time, usually two people to pull the boom is operated, a pull of a release the boom slowly rotating, if one direction, then yanked, It would boom out of balance causing unnecessary losses.
