Multi-link automotive alignment lift

摘要

An automotive lift comprises a pair of runway sections. Each runway section comprises a deck portion, two pairs of legs, and a pair of elongate sliding members. The pairs of legs are pivotally coupled with the deck portion. The elongate sliding members are pivotally coupled with the pairs of legs and are slidable relative to the deck portion. A hydraulic cylinder assembly is coupled with the deck portion by a clevis and with the elongate sliding members by a piston and piston block. The hydraulic cylinder assembly is operable to translate the elongate sliding members relative to the deck portion, thereby pivoting the pairs of legs relative to the deck portion to lift the deck portion relative to the ground. A hydraulic system is operable to synchronize lifting of the runway sections. A braking mechanism is configured to restrict descent of the runway sections.

主权项

1. An automotive lift, comprising:
(a) a first runway section, wherein the first runway section comprises:
(i) a deck portion,(ii) a first pair of legs, wherein the first pair of legs comprises a first leg and a second leg,(iii) a second pair of legs, wherein the second pair of legs comprises a third leg and a fourth leg,(iv) a first elongate member comprising a first end and a third end, wherein the first end is pivotally coupled with the first leg, and the third end is pivotally coupled to the third leg such that the first elongate member extends from the first leg to the third leg, and(v) a second elongate member pivotally coupled with the second and fourth legs,wherein the first and second elongate members are slidable relative to the deck portion; (b) a second runway section, wherein the first and second runway sections are operable to engage a vehicle, wherein the first and second runway sections are configured to raise and lower a vehicle relative to the ground; and (c) a hydraulic system operable to selectively raise and lower the first and second runway sections relative to the ground.
