摘要： PURPOSE:To make the whole of equipment more compact and easily handlable by constituting the equipment with a box body, a base frame, drum frame and roof body, providing a projected portion at the center of roof body, locating flat attaching surfaces at both sides of the projected portion, and providing suspending fittings on the attaching surfaces. CONSTITUTION:The box body comprises 3 elements of a base frame 1, a drum frame 2 of a cubical shape placed on this base frame 1, and a roof body installed on the drum frame 2. The roof body has a projected portion 4 swelled in a circular arc form upwardly at the center, has horizontal attaching surfaces 5, and suspending fittings 6 are placed on the attaching surfaces 5. A transformer 12 for circuit and a load switch 13 are housed inside the drum frame 2. The roof body forms a space 14 inside by the projected portion 14, thereby making the arrangement of built-in air ventilator and instrument transformer 15 effective and easier. Mounting position of suspension fittings 6 is lower than the projected portion 4 and thus does not project out from the outer shape of the whole of equipment so that does not disturb carrying or the like. By doing this, the whole of the cubicle high voltage equipment can be made smaller and handled more easily.

摘要： PURPOSE:To reduce the fatigue of a worker by reducing work in a half-sitting posture and to safely and efficiently perform painting work. CONSTITUTION:A jib A having a triangular cross section for a crane formed by mutually integrally connecting three main frames 1a, 1b, 1c by auxiliary frames 2... is received by the receiving seats of jib receiving stands B at four places near to the connection flanges 11 of both ends of the jib in the longitudinal direction thereof in such a state that two main frames 1b, 1c positioned above one main frame 1a floated with respect to the ground mutually become the same level to be supported on the jib receiving stands B. In this state, the surfaces of the main frames 1a, 1b, 1c and the auxiliary frames 2... are painted.

摘要： PURPOSE:To shorten downtime by emitting a failure signal when power failure to a crane remotely controlled is sensed, actuating a confirming means on the crane body side, by making sure how the failure is, and by initiating repairing procedure immediately. CONSTITUTION:Outputs from a voltage setting device 16b and a voltage sensor 16a incorporated in a power failure sensing means 1 are compared at a comparing means 27. The leak current is sensed by a current sensor 17a and compared with the set value of a current value setting device 17b at another comparing means 28. When the result from comparison is greater than a specified value, it is judged that either voltage or leak current is not proper, and a power failure alarm means 2 is informed of it to actuate alarm means 2a, 2b, twinkle a light 24, and inform a confirming means 4. An operator turns a confirming switch 3 to make sure the condition with power failure. This accomplishes making sure the power failure in a short time, which permits immediate initiation of repairing work, and thus the downtime is shortened.

摘要： PURPOSE: To reduce the number of signal wires by outputting a wave motion signal from a transmission means of a lifting device to a receive means by a drive stop signal through a mast from an operation control part to open and close a door when a lifting device main body moves to a predetermined story. CONSTITUTION: A signal wire 28 is attached along a mast 1, and one end thereof is connected with an operation control part installed on the ground and the other end thereof is connected with a transmission means 21 on a load carrying platform 2 of a lift. Moreover, a receive means 23 and a transmission means 24 are arranged on a floor 10 of a building in opposition to the transmission means 21 on the load carrying platform 2 of the lift and a receive means 22. When a detection means L1 detects that the load carrying platform 2 of the lift moves to a predetermined story, the operation control part sends a drive stop signal to the transmission means 21, sends an optical signal to the receive means 23 from the transmission means 21, drives a motor 18 to open a front door 17, and drives a motor 16 through the transmission and receive means 24, 22 after confirming it to open a door 15. Consequently, the installation of a signal wire in a floor duct is not required, the number of signal wires can be reduced, and construction term can be shortened.
