Adjustable locating heavy-load elevator

The invention discloses an adjustable locating heavy-load elevator. According to the elevator, translation adjustment is conducted on a front-arranged wheel or a rear-arranged wheel of a carrier through adjustment caterpillar bands; non-straightness of the carrier body or an oblique carrier is corrected; and the carrier faces an exit directly and pulls out smoothly. Driving is conducted through aroller motor, the power is strong, and space is saved; and meanwhile, bidirectional flexible rapid response can be made. Friction with tires can be increased through a friction layer; sudden braking when the carrier enters is convenient; and the tires do not slip. Through structural blocks, mechanical performance of the adjustment caterpillar bands can be increased and adjusted better, and bearingof heavy type carriers is convenient. Through a supporting assembly, the carrier can be better prevented from being overweight; and the situation that the middle of the adjustment caterpillar bands collapses and deforms is ad
