Children's play is based on the engineering excavator excavator works with the design and development of an educational play equipment, all the parts for export standard engineering durable parts, using international advanced technology, has been successfully applied for national patents, elegant simplicity, workmanship, electric hydraulic excavators for the whole simulation. Operation, function and engineering excavator same can be rotated. Suitable for indoor and outdoor playgrounds in parks, squares, scenic areas and other places. Child psychology experts confirmed that growth and development of children should have more contact with hands-class recreational facilities, intellectual development of children up to exercise children hands-on brain coordination. Can be 60 degrees, 90 degrees rotation free exchange, and to be based on the size of your site to adjust the rotation angle. Business diversification, operating experience, contests, also according to the digging of the award, participate in interactive games, appearance, * strong attendance advantages, since the market by the majority of users of all ages and praise. Product: Children's play toy excavator excavator is a full simulation, have dug deep down, 360 degrees, 180 degrees, or 90 degrees of rotation, through his open hands to experience the fun of the excavator is the most amusement park project Good choice. ? Help First, the machine steady expansion bolts in place using a solid flat surface, and the installation of the fence, the fence nearest distance itself should be more than 1.5 meters. Second, this machine uses 220v AC power, use with leakage protection switch and ground power supply voltage in order to ensure stable and reliable power supply line should be 3 * 2.5 square copper, 2 meters away from the main power supply. Third, before use of hydraulic oil filling, it is recommended to use the brand of hydraulic oil, the oil must be counted among the 80-90 level. Fourth, work equipment joints should be filled with oil. Five consecutive starts for the first time the boot should stop more than three times, and the empty run over five minutes to eliminate gas pipeline in ??. (Winter temperatures below 0 degrees before starting the day idling five minutes preheat) before six, machine debugging appearances are normal, moderate speed, the speed to be adjusted as described below, refer to: 1. hydraulic valve control device above the speed can be adjusted The pressure regulator, clockwise to increase pressure, counter-clockwise to reduce the pressure (for the whole pressure) 2. Adjust the speed of a single action, adjustable hydraulic valve in the middle of the control valve, the corresponding work for every single action turn it clockwise to reduce the pressure, counterclockwise rotation as the pressure increases, the amount of rotation because of need. ? ?? 3 Fence Installation: 1.4 * 1.5 meters on both sides of the protective net 2 and a height of 1.5 meters, after the ???????? 0.75 * 1.5 m protective net, previous 0.6 * 1.2 m Protection Network 2 and the upper side is flat, the next leak yellow iron, 0.6 * 1.2 m protective net and machine pedal at M5 bolts connected by serial number with M5 * 5 cm bolt connected. History of the development of children's play in Japan and South Korea and other developed countries excavator has been popular for several years, has just started in China, the introduction in 2011 of production (currently the only manufacturer), into the market response is good, the majority of users of all ages . ?
