Beyond
heavy lifting: loaders perform a variety of tasks from material
handling to primary demolition
Recycling Today,
Nov, 2004 by Deanne Toto
The loaders employed at recycling facilities and at construction
and demolition recycling sites perform a variety of material handling
tasks, but their usefulness goes far beyond loading processing
equipment and outbound trucks.
It's this versatility that many manufacturers are keeping in
the forefront as they design the next generation of material handling
equipment, whether they be wheel loaders or skid-steer loaders.
Faced with these choices, selecting the right mix of equipment
for a particular recycling yard or demolition job can be somewhat
intimidating. However, determining the right loader typically
starts with the material to be handled and the level of production
required.
IN THE SHOWROOM "A few key considerations that affect
equipment selection would be the size of the job, the type of
material being removed and the height of the structures,"
Rusty Schaefer, marketing manager for Case Construction Equipment,
Racine, Wisc., says. "Additional considerations include dust
control, sound restrictions and lift capacities of the equipment."
Schaefer adds that demolition contractors should also consider
their project deadlines in order to determine the number of pieces
of equipment needed and the way in which the machines will be
used.
Kelly Moore, product manager for Gehl, West Bend, Wisc., says
that while compact equipment may be more suitable for jobs with
space restrictions, he suggests that choosing the largest loader
a site will allow enables the contractor to increase his productivity
by getting more done in less time.
"Large equipment allows for more production on open projects,"
Lance Mathern, marketing manager for Bobcat Co., West Fargo, N.D.,
agrees. However, he adds that compact equipment, like skid-steer
loaders, is often less expensive, easier and quicker to transport
on and off site, can fit into tight spaces and can operate a variety
of attachments.
Nell LeBlanc, senior marketing consultant for Caterpillar Inc.,
Peoria, Ill., says that in the highly competitive demolition field,
a contractor is most concerned with machine versatility, durability
and dependability.
"All machines working at a site are often needed to perform
multiple tasks. Various work tools, properly applied, are the
key to success," he says.
As far as durability and reliability are concerned, Leblanc says,
"Machines and work tool designs must afford for maximum up
time when utilized in harsh environments.
With this information in mind, selecting among the variety of
wheel loaders and skid steers available should be a bit easier,
though both machines offer different strengths that may be more
suitable for a given job.
FREE WHEELING "In demolition, the wheel loader most
often supports the primary demolition tool, the excavator,"
Jack Bolton of Volvo Construction Equipment, Asheville, N.C.,
says. "The loader can set barricades and set steel plates
with a set of forks or a material handling arm. When equipped
with a broom, the loader can clean dust and debris blown out from
the demolition site. Of course, when the loader has a bucket,
it can load tracks and clean large debris from haul roads,"
he adds.
Leblanc says wheel loaders are often used to move bulk quantities
of demolition debris, such as crushed concrete, blocks and wood,
in primary and secondary demolition applications. "Staging
materials and loading trucks are a common requirement," he
says.
"In terms of demolition, a wheel loader is primarily a tool
carrier because of its ability to change attachments," David
Morice, heavy-range equipment manager for JCB Inc., Pooler, Ga.,
says.
When equipped with hydraulic couplers, which allow for quick
attachment changes, Case's Shaefer points out that wheel loaders
can be equipped with forks, scrap grapple buckets and brooms,
increasing their versatility and utilization.
SKIDDING ALONG "Overall, skid loaders are probably
more predominant in recycling or demolition because of their versatility,"
Gehl's Moore says. "For overall purposes, whether it is any
kind of recycling or demolition application, the skid loader is
really going to be the best performer and producer that a contractor
can look for," he says, crediting the machine's versatility.
Dan Rafferty, compact equipment product manager for JCB Inc,
Pooler, Ga., says that skid steers offer small to midsize recyclers
the versatility needed to handle multiple tasks thanks to the
machines' quick-taches and auxiliary hydraulics.
LeBlanc also finds skid steers to be the most versatile equipment
in recycling and demolition applications. "Their compact
size, lightweight, nimble maneuverability, ease of operation and
endless array of work tools allows the SSL (skid-steer loader)
to perform many functions."
Additionally, compared to a wheel loader, Moore says a skid loader's
cycle time is going to be considerably faster.
"In demolition, skid-steer loaders are typically used for
interior demolition or exterior flatwork" Bobcat's Mathern
says. "For example, they can be equipped with a breaker,
drop hammer, wheel saw or planer attachment to demolish concrete,
asphalt, etc., and then switch to an industrial fork or bucket
grapple to remove material."
Mathern continues, "In recycling operations, SSLs play the
cleanup role. SSLs equipped with an industrial fork or bucket
grapple typically remove debris from the immediate demolition
area, particularly from tight places." Additionally, skid
steers are often used to cleanup around processing equipment,
removing any debris that may fall off conveyors or from the machinery
itself and to remove the processed material, he says.
For many, the benefit of skid steers lies in their maneuverability
and versatility.
"The real benefit of skid steers in any application is their
maneuverability in confined areas," Schaefer says. "When
used with hydraulic couplers and a vast array of attachments (shears,
hammers, scrap grapple buckets, pallet forks, brooms) skid steers
can be highly utilized machines."
Clearly, versatility remains a key consideration when selecting
loaders for use in recycling applications and in demolition applications,
particularly. Manufactures are doing their best to deliver durable,
dependable equipment that is up to the challenge.
"Any machine and tool combination that can improve productivity
and minimize manual labor--demolition contractors are very concerned
about skilled labor shortages in their industry--is a priority,"
Leblanc says. "Equipment versatility will help to ensure
that a contractor remains competitive for years to come."

ROLL ON
Because of the rigors of demolition environments, contractors
may wish to consider solid or foam-filled tires for their loading
equipment in order to reduce downtime resulting from flats and
wear.
Kelly Moore, product manager for Gehl, West Bend, Wisc., says,
solid tires are the best choice for demolition environments in
terms of wear and puncture resistance, though they provide a harder
ride. "If they are traveling longer distances at higher ground
speed, some customers might prefer to go to severe-duty ties that
can be air inflated or poly inflated. With the poly material,
you still get the same softness as when you have air in the tire."
Jay Barth of JCB Inc., Pooler, Ga., says steel-belted, severe-duty
mining tires have good characteristics in these applications.
He says these tires may be a bit easier to change than the foam-filled
tires, which can be difficult to dismount.
