Part 6 Cranes, Hoists and Lifting Devices

Section 112 Safety standards

Section 112(a)

ANSI Standard ANSI/ALI ALCTV-2006, American National Standard for Automotive Lifts – Safety Requirements for Construction, Testing and Validation, lists requirements for the construction, testing and validation of automotive lifts that are

(a) manually driven,
(b) power driven,
(c) stationary, or
(d) mobile.

The lifts can be installed “in-ground” or at the surface (see Figures 6.46 through 6.50 for examples). The Standard does not cover lifts that are moveable, designed to tilt the superstructure, or are not “automotive vehicle service lifts”.

Figure 6.46 Two post, wheel or axle engaging, moveable piston, in-ground lift

Figure 6.47 Single post, frame engaging, in-ground lift

Figure 6.48 Two post, frame engaging, clear floor, surface mounted lift

Figure 6.49 Roll-on, scissors, surface mounted, hinged lift

Figure 6.50 Four post, surface mounted lift

The Standard describes the installation, operation, inspection and maintenance instructions that must accompany each hoist. These include:

(a) design specifications;
(b) installation instructions;
(c) safety instructions;
(d) operating instructions;
(e) inspection and maintenance instructions; and
(f) identification of vehicle lifting points.

The Standard describes labelling requirements for

(a) safety warnings and instructions,
(b) components,
(c) electrical safety,
(d) product identification, and
(e) third-party certification.

The third-party testing, evaluation and certification of these vehicle lifts must be conducted by a laboratory that is accredited by the U.S. Occupational Safety and Health Administration.

Section 112(b)

ANSI Standard ANSI/ALI ALOIM-2000, Automotive Lifts – Safety Requirements for Operation, Inspection and Maintenance, lists requirements for the operation, inspection and maintenance of installed automotive lifts.

Section 4.1 of the Standard describes operator qualifications which include

(a) a demonstrated ability in written or oral communication,
(b) a demonstrated ability to understand the mathematical, mechanical and electrical principles of automotive lifts, and
(c) a demonstrated physical ability to carry out operator responsibilities in a safe manner.

Section 4.4 of the Standard describes operator responsibilities which include:

(a) using all safety features and operating the lift in accordance with the manufacturer’s instructions;
(b) maintaining the lift in a clean and orderly manner;
(c) conducting a daily inspection for and of:

(i) operational controls;
(ii) deformation and excessive wear of structural components, hoses, wires, drive chains, cables, screws, lift contact points; and
(iii) evidence of hydraulic and pneumatic leaks, unusual noises or movements, cracked or loose concrete around anchor bolts.

Part 5 of the Standard describes the requirements for periodic, documented inspections that must be carried out in accordance with the manufacturer’s instructions and in no case less than annually. Periodic inspections must be carried out by an inspector with:

(a) knowledge of personal safety practices;
(b) the ability read and understand manuals, drawings, parts lists;
(c) knowledge of the function of all components, devices, accessories;
(d) a working knowledge of the principles of the following as applied to the operation and components of the lift:

(i) electrical and electronic control circuits,
(ii) mechanics,
(iii) hydraulics,
(iv) pneumatics, and

(e) knowledge of the types, styles, uses and limitations of lifts.

Periodic inspections must include, but not be limited to, the following:

(a) presence of required labelling;
(b) confirmation of adequate clearances;
(c) examination of structural components such as electrical components, lift controls, runways including runway stops, swing arms including swing arm restraints, fastening devices, exposed surfaces and edges, lift adaptors;
(d) operation of the lift through its full cycle;
(e) lowering speed when carrying a representative vehicle;
(f) operations of synchronization or equalization systems;
(g) working platforms, railings, stairways;
(h) operation of up over-travel shutoff switch;
(i) all chains and cables including checking for tracking and level winding;
(j) potential pinch points;
(k) presence of water in pits or enclosures; and
(l) lift system checks for hydraulic lifts, mechanical lifts, hydraulically-driven mechanical lifts and pneumatic lifts.

Part 6 of the Standard describes requirements for preventive maintenance and repair maintenance.
