it’s already a given that extended schedules cause 3. Heightened Exposure to Accidents & Liability. Here’s
one to pay more for general requirements (GR) - one we recently had happened to us on a project,

4. Loss and Disruption of Future Work Opportunities.
A stark reality for most contracting firms is that
their company resources are (more or less) finite.
That is - regardless of size of scale – any particular
company model is built around a relatively static
number of employees in the field and a known
quantity of ancillary resources (i.e. equipment) that

which your mechanic is exposed while he/she is working on
the crane.
Question 5: I lease a crane to a construction contractor. I do
not provide an operator for the crane, nor do I have anyone
inspect or repair the crane while it is on the site. Do I have any
responsibilities under the standard?
Answer 5: No. An employer who leases (or sells) a crane but
does not send any employees to the worksite where the
crane is used is not subject to the standard. However, as
noted in Answer 2, the lessee is responsible for the condition
of the crane and may ask you to produce written records of
past crane inspections or to provide other information about
the crane.
Question 6: I am a contractor on a construction site. Another
contractor is using a crane on the site. None of my work
involves the crane. Do I have any responsibilities under the
standard?
Answer 6: Yes, because your employees may be exposed
to hazards caused by the crane’s operation. For example,
if a crane collapses due to being overloaded, employees
working elsewhere on the site can be killed or injured. And if,
for example, a crane makes electrical contact with a power
line, any employee touching or even near the crane can be
electrocuted.
Even though you are not operating the crane, you must
be aware of potential crane hazards and are responsible
for protecting your employees against hazards you can
reasonably foresee. You must take reasonable steps to
protect your employees. For example, if you are concerned
with a crane’s stability due to potential overloading, unstable
barge conditions, or high winds or wave action, you must
satisfy yourself that the crane is stable before allowing your
employees to work where they would be in danger if the
crane collapses. One way is to ask the company operating
the crane or the controlling contractor on the site whether all
necessary precautions are being taken to ensure the crane’s
stability. Also, you have a duty to train your employees in the
hazards associated with their work, including those that might
arise from working near a crane.
Question 7: What training must I provide to my employees?
Answer 7: Training that must be provided under the standard to
equipment operators, signal persons, competent and qualified
persons, maintenance and repair workers, and workers who
work near the equipment can be found by reading O.S.H.A.
Section 1430. Additional training requirements are specified
in other provisions of the standard. In addition, 1926.21(b)
(2) requires employers to train construction workers how to
recognize and avoid the hazards associated with their work
and, depending on the circumstances, may require training
in topics not listed in the cranes and derricks standard. n

SHEET PILE DRIVER FROM NPK

NPK's excavator-mounted sheet pile driver is
a modi ed design of industry leading plate
compactors, adapted to direct powerful
vibration forces downward, optimizing driving
of sheet pile. Durable, shock-absorbing rubber
mounts protect the excavator's boom and stick
from vibration and shock loading. The mobility
and maneuverability of NPK sheeting drivers
permit operation in many areas previously
inaccessible: under low clearance obstructions
(bridges, etc.), around bridge piers, and next
to walls. This makes picking up, moving and
aligning the sheeting easy and stress-free
when driving and/or extracting. Designed for
excavators from 16,000 lbs. to 100,000 lbs.

• 180° free rotation allows precise alignment and positioning of the sheet
pile without having to reposition the machine. When not needed the swivel
can be locked into place; either parallel or perpendicular to the boom.

• Dedicated top mounting brackets, designed to OEM bucket speci cations,
provide a full range of motion when picking up the sheeting from the
ground.

• Simple operation means that any excavator operator can easily drive and
extract piling.

• Clamp tted with a hydraulic cylinder lock to prevent slippage.
• Shock-absorbing rubber mounts isolate vibration and reduce noise.
• Heavy duty, high e ciency gear motor.
• Integrated ow control and pressure relieving valves protect from

excessive ow and pressure.
• Oil splash lubrication eliminates routine greasing of the bearing.
