Abstract

A weld splatter removal system for a boom includes at least one wear pad and at least one scraper. The at least one wear pad is securable to one of an outer boom and an inner boom. The at least one scraper is secured to each wear pad of the at least one wear pad. The at least one scraper is operable to contact a surface of the other of the outer boom and the inner boom and remove weld splatter from the surface in response to extending and retracting the inner boom with respect to the outer boom.

Claims (20)

1 . A lift device comprising: a chassis; and a boom assembly movably secured to the chassis, wherein the boom assembly includes, a first telescopic boom, a second telescopic boom disposed within the first telescopic boom; wear pads disposed between the first and second telescopic booms; and scrapers disposed on the wear pads and operable to remove weld splatter from a surface of one of the first and second telescopic booms in response to extending and retracting the second telescopic boom with respect to the first telescopic boom.
2 . The lift device of claim 1 further comprising magnets disposed on the wear pads, wherein the magnets are operable to collect the weld splatter upon removal of the weld splatter from the surface.
3 . The lift device of claim 1 , wherein the surface is a lower surface of an upper panel of the first telescopic boom.
4 . The lift device of claim 1 , wherein the wear pads and scrapers are disposed on a top surface of an upper panel of the second telescopic boom.
5 . The lift device of claim 1 , wherein the first telescopic boom is an outermost boom of a plurality of telescopic booms.
6 . The lift device of claim 1 further comprising shims disposed between the wear pads and one of the first telescopic boom and the second telescopic boom.
7 . The lift device of claim 1 further comprising fasteners securing the scrapers to the wear pads.
8 . A weld splatter removal system for a boom comprising: at least one wear pad securable to one of an outer boom and an inner boom; and at least one scraper secured to each wear pad of the at least one wear pad, wherein the at least one scraper is operable to contact a surface of the other of the outer boom and the inner boom and remove weld splatter from the surface in response to extending and retracting the inner boom with respect to the outer boom.
9 . The weld splatter removal system of claim 8 further comprising at least one magnet disposed on the at least one wear pad, wherein the at least one magnet is operable to collect the weld splatter upon removal of the weld splatter from the surface.
10 . The weld splatter removal system of claim 8 , wherein the surface is a lower surface of an upper panel of the outer boom.
11 . The weld splatter removal system of claim 8 , wherein the at least one wear pad and the at least one scraper are disposed on a top surface of an upper panel of the inner boom.
12 . The weld splatter removal system of claim 8 further comprising at least one shim disposable between the at least one wear pad and one of the outer boom and the inner boom.
13 . The weld splatter removal system of claim 8 further comprising at least one fastener securing the at least one scraper to the at least one wear pad.
14 . The weld splatter removal system of claim 8 further comprising an adhesive securing the at least one scraper to the at least one wear pad.
15 . A method of removing weld splatter from a boom system comprising: securing an auxiliary wear pad having a scraper secured thereto to one of an inner boom and an outer boom at a location that is between the inner boom and the outer boom such that the scraper contacts a surface of the other of the inner boom and the outer boom; and extending and retracting the inner boom relative to the outer boom such that the scraper scrapes the surface of the other of the inner boom and the outer boom removing the weld splatter therefrom.
16 . The method of claim 15 further comprising removing a primary wear pad from the location that is between the inner boom and the outer boom prior to securing the auxiliary wear pad to one of the inner boom and the outer boom at the location.
17 . The method of claim 16 further comprising collecting the weld splatter upon removal of the weld splatter from the surface.
18 . The method of claim 15 further comprising placing shims between the auxiliary wear pad and one of the inner boom and the outer boom to position the scraper such that the scraper is in contact with the surface.
19 . The method of claim 15 further comprising removing the auxiliary wear pad and the scraper from the boom system subsequent to removing of the weld splatter from the surface.
20 . The method of claim 19 further comprising securing the primary wear pad to one of the inner boom and the outer boom at the location subsequent to removing the auxiliary wear pad and the scraper from the boom system.

Description

TECHNICAL FIELD The disclosure relates to lift devices that are operable to handle materials, elevate work platforms, etc. BACKGROUND Lift devices may include material handlers, platforms, or other components that may be elevated relative to a corresponding base structure. SUMMARY A lift device includes a chassis and a boom assembly. The boom assembly is movably secured to the chassis. The boom assembly includes a first telescopic boom, a second telescopic boom, wear pads, and scrapers. The second telescopic boom is disposed within the first telescopic boom. The wear pads are disposed between the first and second telescopic booms. The scrapers are disposed on the wear pads and are operable to remove weld splatter from a surface of one of the first and second telescopic booms in response to extending and retracting the second telescopic boom with respect to the first telescopic boom. A weld splatter removal system for a boom includes at least one wear pad and at least one scraper. The at least one wear pad is securable to one of an outer boom and an inner boom. The at least one scraper is secured to each wear pad of the at least one wear pad. The at least one scraper is operable to contact a surface of the other of the outer boom and the inner boom and remove weld splatter from the surface in response to extending and retracting the inner boom with respect to the outer boom. A method of removing weld splatter from a boom system includes securing an auxiliary wear pad having a scraper secured thereto to one of an inner boom and an outer boom at a location that is between the inner boom and the outer boom such that the scraper contacts a surface of the other of the inner boom and the outer boom. The method further includes extending and retracting the inner boom relative to the outer boom such that the scraper scrapes the surface of the other of the inner boom and the outer boom removing the weld splatter therefrom.
