个人觉得：很便宜的弯管铬钼钢或锰钢滚笼，对于塌方这种事救大量人命，重伤变轻伤，轻伤变皮肉伤？如果能有专业检验刚性/拉伸的结构车检，mot inspection对于滚笼/自动灭火器（俄Celica车友Feudor搞的潜艇钛合金发动机+自动传感灭火器简单有效，一直佩服。当然电车就不要想灭火器了，灭火器对EV或者说锂镁钠之类根本无效，泼水都不降温反而引发H2O=氢气大爆炸）这类理应尽量放松，毕竟钢管结构极为优化想搞砸也难。有意见说缩小空间出来较慢。。。那完好的人出来得要努力一些，总是怎么也比肉泥出不来强多了吧。
更老猴年马月老图：全速冲撞了泥石流塌方，俩人屁事儿没有爬出来。
像我这种自己从淘宝海运来4130钢管（1-3/4" OD，0.100"超厚，一个人单枪匹马3个月DIY焊完，大概区区～$400-500）手焊的30年老破，外加自己接线主断路器+一切手动无助力+车内和发动机舱2台灭火器备用，要是遇到这种塌方事件，便宜老破车能救命吧？
Ah pauper's dillema, I really love manual bender always thinking buy or make one, but pauper as pauper... Anyway some practical cost info here, hope helps:
45mmOD, *2.5mm thick 4130, 30m, 1700CNY=8700baht delievered
(1 3/4" * 0.100" AISI 4130 seamless that is 100ft=240USD)
38mmOD, *1.5mm thick 4130, 3m, 120CNY=800baht delievered
(1.5" * 0.060" AISI 4130 seamless that is)
24cubic meter argon, 2800baht
Miscs tubings, 304 and cold roll plates, ~1000baht
1.6mm & 2mm 309L, 2kg, 100CNY=500baht
1 broken 46mm Milwaukee holesaw 430baht.
Oxygen, LPG, Electricity etc, maybe 100-200baht?
ginder supplies, maybe ~600baht
plus my ol friend notcher jig 350CNY=1750baht, but those served me longtime doesn't count into budget of this cage
TOTAL 15000baht=411USD( oops made a mistake, edit corrected ), Oh, btw. This INCLUDES tubular frontend. So 411USD=makeshift cage+tubular frontend
