| If you are looking for an alternative to the
OEM's for design changes, capacity upgrades or engineering support, then
Simmers is that alternative. We won't try to sell you a new crane or component
unless you absolutely need one or it is the best of all alternatives. Simmers
has been performing capacity analysis and engineering design services since
1958 on various crane manufacturers equipment including but not limited
to: Alliance Machine, Bedford, Browning, Cleveland, Crane Manufacturing
and Service, Demag, DeShazo, Ederer, Gaffey, Harnischfeger (P&H), Kranco,
Kone, Landel, Manning Maxwell & Moore, Mecomatic, Morgan, Northern, Paceco,
Reading, Stanspec, Virginia, Zenar. Our engineering staff consists of electrical,
mechanical and civil engineering personnel, many of which are Registered
Professional Engineers.
Capacity Analysis:
Calculations are performed to verify existing lifting capacity or an
increase in lifting capacity due to process changes or crane application.
Calculations are performed according to nationally recognized specifications
( CMAA, AISE, AGMA, etc) in order to assure compliance with codes and
adequate mechanical, structural or electrical design.
Runways:
When increasing crane lifting capacity or adding a crane to an existing
building, the runway and its support structure must be evaluated for
the increase in loading. Girders, rail, columns, tie backs and foundations
are inspected and analyzed per AISE, AISC and BOCA specifications and
codes.
Respans:
Relocating an existing crane may require a change in span. Changing a
crane span requires more than just cutting and splicing girders together.
An engineered cut is located at the least stressed point in each girder
and is geometrically configured such that the integrity of the weld
is sufficient for years of proper operation.
Specifications:
Long term crane performance begins with a well defined specification
with the enhancements you desire. The most common crane problems occur
when a crane is misapplied to the application. Simmers can help you
identify the application and the proper duty cycle and crane classification
whether it is CMAA Class A, B, C, D, E or F or an AISE TR#6 Service
Classification I, II, III, or IV. We also recommend enhancements to
certain classification in order to provide you better value or identify
your specific preferences.
Engineered Lifts:
OSHA specifies when and engineered lift can be performed and at what
intervals. Simmers can help you execute such infrequent lift requirements,
thus avoiding a complete capacity upgrade.
Modernizations:
If your workforce desires to perform the field work, our engineering
staff will provide design and coordination services to assure proper
component selection, code compliance and installation supervision,
assuring you the job will be done right the first time. Unforseen problems
that usually arise during any modernization can be resolve quickly
and efficiently by having an on-site qualified person at your side.
Re-engineering:
Having problems obtaining obsolete components or just can't wait for
the OEM to respond in a timely manner? Simmers is your answer. We will
design replacement drums, wheel assemblies, sheaves, end trucks, gearing,
girders, frames, shafting, couplings, hooks, etc. Engineering calculations
will be performed to support our designs. |
