For balance, the safety frame 105 extends long to the rear of the carrier 100, but the safety frame 9 or safety frame 9' of the present invention has a "spring-up position" 9b or 9'b.
It does not extend to the rear of the carrier 1 or 1' for a long time, and also prevents it from falling in the direction of the arrow 18b from the "spring-up position" 9b or 9'b.

Further, since the spring type flip-up device 14 has a spring cover 33 fitted over the spring 32, it prevents the clothes of the passengers from getting caught.

(c) Effects of the invention The lift with a safety frame of the invention has the following advantages over conventional ones.

By being equipped with a spring-type flip-up device,
Since it is not necessary to balance the weight at the center of rotation of the safety frame, the safety frame can be made smaller, and the weight and size of the carrier in the direction of travel of the carrier can be reduced.

By reducing the weight of the carrier and the dimensions of the carrier in the direction of travel, it is possible to reduce the space for motive equipment such as prime movers and garage lines or side tracks installed at the foot of the mountain or at the summit terminal of the automatic circulation cableway. .

The spring-type flip-up device has a mechanism that allows the flip-up force to be adjusted, so even if other equipment such as a footrest frame is attached to the safety frame, the same spring-type flip-up device can be used. A spring cover is placed over the spring to prevent passengers' clothes from getting caught.

The carrier frame bulges out on both sides near the backrest, making it easy to get on and off the vehicle.

In view of the above-mentioned points, the present invention can provide a carrier with a safety frame for a lift that allows safe riding and is economical in equipment cost.
