MOTIVATION
CHECKERBOOM PORTABLE
GANTRY CRANES
INTRODUCTION
PROVEN DESIGN
Motivation Industrial Equipment has been designing and
manufacturing gantry cranes and lifting equipment continuously
since 1968. Thousands of Checkerboom gantry cranes, pedestal
cranes, floor cranes and jib cranes are in regular service, many
at some of the largest manufacturers, utilities, government and
military establishments in North America. All design, engineering
and fabricating is done by Motivation in Motivation's own
facilities.
SAFETY
Motivation's goal has always been to design and manufacture
quality equipment to industrial standards. Motivation gantry
cranes are designed to meet applicable sections of CSA S16-1969
standard and CMAA specification No. 74-1987. The maximum
calculated deflection does not exceed (span/600) where the span
is given in inches. Material for all gantry cranes shall conform
to CSA G40.21-87 Structural Quality Steels, minimum grade 44W
steel. All Motivation gantry cranes are welded in accordance with
CSA W47.1-1983 and CWB W59-1989. Motivation is certified to CSA
W47.1. CASTERS ARE DESIGNED TO TAKE THE FULL RATED CAPACITY OVER
ONE A-FRAME. The included safety factor provides a margin of
strength to allow for variations in the properties of materials
and manufacturing and is not intended to provide authorization or
protection for users to load the crane above the rated capacity.
Standard equipment is designed for industrial use, not for
lifting of human cargo.
STABILITY
For optimum stability of the gantry, the ratio of the height
under the beam to the overall width of the base is 2:1. This
ratio must be maintained when adjusting adjustable height
gantries.
QUALITY AND PRICE
Although Motivation Gantry cranes are very competitively priced,
quality has not been sacrificed. Competitive pricing and quality
results from Motivations specialization in gantries, jib cranes,
and related products, all in regular production, with facilities
expressly geared to this production. Welders and fitters are
second to none in experience and workmanship. All material is
thoroughly checked before fabrication and all welds are closely
inspected. Dimensions and weights shown are approximate. In the
continued search for product improvement, Motivation reserves the
right to change specifications without notice. General
arrangement drawings showing critical dimensions are available
upon request.
WARRANTY
Every Motivation crane is inspected before shipment and is
guaranteed against defects in workmanship and materia1 for a
period of twelve months from the date of shipment.
