Group 7's project focuses on site dumpers. Site dumpers are open vehicles used to carry bulk materials on construction sites. They have the load skip in front of the driver and can tip the skip to dump loads. The group evaluates several common site dumper models from manufacturers like Nu-Star, Terex, Wacker Neuson, and MZ Imer. These dumpers have payloads from 2,200 to 13,000 pounds and are powered by diesel engines. Proper training and safety precautions are needed when operating site dumpers to prevent overturning, which is a major cause of accidents.

3.  A dumper is a vehicle designed for carrying bulk
material, often on building sites.

4.  Dumpers are distinguished from dump trucks by
configuration: a dumper is usually an open 4-
wheeled vehicle with the load skip in front of
the driver, while a dump truck has its cab in
front of the load. The skip can tip to dump the
load; this is where the name "dumper" comes
from. They are normally diesel powered. A
towing eye is fitted for secondary use as a site
tractor. Dumpers with rubber tracks are used in
special circumstances and are popular in some
countries.

7. 2:TerexTA6Site Dumper
Designed as dedicated
haul-and-dump vehicles, the 6-ton Terex site
dumpers (models TA6 and TA6s) have a power
train that combines a 74-horsepower Tier 4-
Final JCB EcoMAX engine with hydrostatic drive

8. 3:WackerNeuson1501Site Dumper
New 1501 articulated site dumper has 3,307
pounds payload capacity and 1.05-cubic-yard
bucket capacity. New 1501 articulated site
dumper from wacker neuson has 3,307 pounds
payload capacity and 1.05-cubic-yard bucket
capacity. Powered by a Yanmar 3-cylinder, 22.8-
horsepower diesel. Folding ROPS protects and
can be folded down for transporting.

9. 4:MZImerSite Dumper
The four-wheel drive MZ 2000 HD site dumper
carries 4,400 pounds of payload, heaped to 1.85
cubic yards, on a rigid front axle and oscillating
rear. Compact Excavator, importer of IHI brand
skid steers and mini excavators, now markets
the MZ Imer site dumper in North America. The
MZ 2000 HD carries 4,400 pounds of payload,
heaped to 1.85 cubic yards, on a rigid front axle
and oscillating rear.

10. Wacker Neuson brings three new articulated
site dumpers to the U.S. market with material-
moving capacities of 2,205 (model 1001), 6,614
(model 3001) and 13,227 pounds (model 6001).
Their dump bodies swivel 180 degrees for
dumping to either side of the machine. Wacker
neuson brings three new site dumpers to the
U.S. market, with material-moving capacities of
2,205 (model 1001), 6,614 (model 3001) and
13,227 pounds (model 6001).

12. The main manufacturers of dump trucks are :
AUSA
Barford
Bell Equipment
Caterpillar Inc.
Doosan
Hinowa
Hitachi
Hydrema

13. Modern dumpers have payloads of up to 10
tons (11 short tons; 9.8 long tons) and usually
steer by articulating at the middle of
the chassis (pivot steering).
They have multi-cylinder diesel engines, some
turbocharged, electric start and hydraulics for
tipping and steering and are more expensive to
make and operate.
An A-frame known as a ROPS (Roll-Over
Protection) frame, may be fitted over the seat
to protect the driver if the dumper rolls over.

14. dumpers have FOPS (Falling Object Protection)
as well. Lifting skips are available for discharging
above ground level.
Dumpers with rubber tracks are used in special
circumstances and are popular in some
countries.

15. Managers play a key role in ensuring the safe
use of compact dumpers.
Managers need to ensure that safe vehicles are
provided and that safe systems of work are
planned and put into practice.
Managers should ensure that all site vehicles:
Are capable of safely performing the tasks they
are expected to perform.
Are operated and maintained according to the
manufacturers instructions.
Are driven by competent drivers.

16. Site dumpers are involved in around a third of
construction transport accidents, causing many
deaths and serious injuries, particularly to
drivers. The main causes of dumper accidents
are:
overturning on slopes and rough ground and at
the edges of excavations, embankments etc.
travelling when a high-lift skip is in its raised
position.
Incidents where a pedestrian is run over by the
front wheels of the dumper.

17. Driver thrown from vehicle while travelling over
rough ground.
Driver error due to lack of experience and
training, e.g accidental operation of controls

18. Managers should:
Ensure that all vehicles are properly maintain
and safe to operate. undertake regular
maintenance and vehicle checks in accordance
with the manufacturer’s recommendations;
operate an effective system for reporting, and
taking any required action on, any defects that
occur.

19. Of the 7 fatal accidents involving site dumpers in
the 5 years to 2010 in Ireland, 6have been
related to dumpers overturning. Always ensure
that adequate precautions are taken to prevent
a dumper overturning or overrunning an edge,
when tipping or driving near, excavations,
embankments, earthworks, water or to any
lower area. Simple control measures such as use
of chocks and stop blocks can prevent these
accidents
