overload: a load that exceeds the rated capacity of the
PALL).
PALD: any one of the various types of portable automotive lifting devices listed in the scope of this Standard.
pawl: a pivoted component that, when engaged with the teeth of a ratchet, prevents undesired movement.
pneumatic power source: a device that utilizes compressed air as the force transmitting medium.
port able: not permanently fixed in one location and able to be moved from one work place to another.
proof load: a load, greater than the rated capacity, applied centrally to the lifting or attaching points of the PALD to confirm the integrity of the structure.
qualified personnel: md iv id uals with characteristics or abilities gained through training or experience or both, as measured against established requirements, such as standards or tests, that enable them to perform a required function.
raised height: the distance from the ground to the top of the saddle at the full extension of the PALL).
ratchet: a toothed member for engagement with the pawl. rated capacitii: the maximum published operating load that the PALD is designated to lift, support. or transport throughout its range of travel.
repair: the process of rehabilitation or replacement of parts that are the same as the original for the purpose of ensuring performance in accordance with the applicable requirements.
saddle: the portion of the PALL) which comes in contact with and/or engages the vehicle or vehicle component.
stability: a measure of resistance to tipping while under load.
supplier: a company that controls the performance spedfication and/or design of the products distributed to the general public.
travel: linear extending or retracting movement of the PALD.
3-3 SAFETY MARKINGS AND MESSAGES
The following are examples of safety markings and messages.
3-3.1 Safety Markings
Safety markings shall conform to the ANSI Z535 series of standards.
(a) Study, understand, and follow all instructions before operating this device.
(b) Do not exceed rated capacity.
(c) Use only on hard level surface.
(d) Lock mounting plate rotating mechanism before applying a load.
(e) Assure load is centered and secured to mounting attachments.
( Failure to heed these markings may result in personal injury and/or property damage.
3-3.2 Safety Messages
Additional safety messages include the following.
(a) Off-center loads may make the load and handle rotate in either direction when the rotational locking device is released.
(b) Release rotational locking devices slowly and carefully.
(c) No alterations shall be made to this product.
(d) Only attachments and/or adapters supplied by
the manufacturer shall be used.
3-4 DESIGN QUALIFICATION TESTING (0
3-4.1 Proof Tests
For each design or design change that may affect the stand’s ability to meet this Standard, sample stands built to design specifications shall be proof tested. The load shall be positioned a minimum of 14.5 in. (368 mm) from the mounting plate and as close as possible to the rotational axis of the mounting plate. To conform with this Standard, the stands shall perform to design specifications and no functional damage shall occur, nor shall operational characteristics be detrimentally affected.
3-4.1.1 Mobility Test. The stand, while loaded to rated capacity, shall be moved in any direction for which the stand was designed. The stand shall, while loaded as above, be moved at 1.5 ft/sec (457 mm/s) to 2.0 ft/sec (610 mm/s) across a 0.5 in. (12.7 mm) high, 15 deg slope rise in the floor, and a 0.5 in. (12.7 mm) drop to the floor, at an approach angle that will bring only one caster or wheel at a time in contact with the rise and drop. The stand shall traverse the rise and drop without loss of load or tipping over.
3-4.1.2 Stability Test. The stand, while loaded to rated capacity, shall be moved at 1.5 ft/sec (457 mm/s) to 2.0 ft/sec (610 mm/s) against a 2.0 in. (51 mm).
