摘要： PROBLEM TO BE SOLVED: To provide a slope maintenance method of a good economical efficiency for a skiing ground, which minimizes melting snow to the least by an artificial snowfall machine while a sufficient amount of snow is secured at an opening time.
SOLUTION: The slope maintenance method for the skiing ground is provided with the first process of spraying artificial snow of a mountain shape on the skiing slope 2 by using the artificial snowfall machine 1 and heaping up a plurality of the artificial snow mountains 3 on the skiing slope before the time of opening the skiing ground, the second process of compacting the snow mountains by applying pressure to make hard compacted lumps 5 and keeping them on standby just before the opening of the skiing ground and furthermore the third process of loosening the compacted snow lumps 5 right before the opening of the skiing ground and spreading the snow over the whole slope as well as compacting it almost evenly so that the skiing slope is prepared and ready for skiing.

SOLUTION: A press plate 22 formed of a wear-resistant flexible material to abut on the snow surface is mounted to the front face lower edge part of a bucket 18 of a work manipulator 4. A workbench is divided in a front workbench 2 liftably supported to a front part on a traveling truck 1 through a lifting means 11, and a rear workbench 3 integrally fixed to a rear part on the traveling truck 1. The work manipulator 4, an operator's seat 12 and an operation box 13 are mounted on the front workbench 3. An engine, a travel driving pump and a manipulator driving pump driven by the engine, and heavy equipment such as a fuel tank, in operating oil tank and a counterweight are placed on the rear workbench 2 being arranged to make the center-of-gravity position of the whole traveling type working machine as low as possible.

摘要： PROBLEM TO BE SOLVED: To provide a course-grooming vehicle having a rear tool carrier capable of uniformly grooming a course without requiring a lot of experience in a role of an operator. SOLUTION: At least one sensor is provided for direct or indirect detection of an actual state of a surface of a course to be groomed by a course-grooming device, and the sensor is connected to a control unit. The control unit comprises a memory for storing at least one characteristic diagram regarding course surfaces of a variety of compositions and attendant nominal set values for height and/or angle of the rear course-grooming device, and an evaluation circuit which compares an actual value detected by the sensor with a corresponding nominal value of the characteristic diagram and actuates the minimum of one adjusting element accordingly as a function of an evaluation result.

摘要： PROBLEM TO BE SOLVED: To provide a snow falling machine capable of producing good quality artificial snow easily and efficiently even though outside air temperature is relatively high. SOLUTION: A static mixer 30 is housed in a downstream region of a confluence portion between a water pressure feed passage 11 and an air pressure feed passage 12 of a nozzle main body 10 which combines water and air supplied under pressure and jets the mixture. As compressed air mixed in is jetted into outside air and the pressure is released, adiabatic cooling and parting of water droplets are carried out thereby cooling fine water droplets, and part of them grows to cores made of ice particles and cooled water droplets stick to the cores thereby growing the ice particles.
