Chad,

I was thinking suitable in appearance and use for a residential garage door. With hydraulics, you can lift / move almost whatever you want to.

About 3 months ago at one of the twin condo towers I was inspecting they brought in a 300 ton rated hydraulic crane to lift into place a large metal covering for a covered passenger loading ares between the two towers. As I recall it had two hydraulic cylinders which raised and lowed the boom, and had 7 axles. Like this, except 300 ton instead of 130 ton and two more axles: QAY130 All Terrain Crane Payload 130 Ton - Yancheng Goldhorse Tractor Sale Co., Ltd
