MAST
TYPE JIB CRANES
|
|
|
|
 |
|
THE
ECONOMICAL 360° SOLUTION |
|
|
|
The
MT Series Crane is floor supported, top stabilized,
and is capable of 360° rotation via a top and bottom
bearing assembly. |
|
|
|
Three
key requirements must be met before deciding
on a Mast Type Jib Crane: |
|
|
|
1.
An adequate structural support to stabilize the crane
at the top of the mast must exist. If the
jib is installed
underneath an overhead crane runway or building
truss, then the deflection of the supporting
member
may not exceed 1/2 inch. |
|
2.
Clearance overhead for the pivot assembly must exist. |
|
3.
Clearance overhead for the boom to rotate must exist. |
|
|
|
AVAILABLE
IN TWO STYLES |
|
1)
MT400 FULL CANTILEVERprovides for maximum
amount of lift where full use of available
headroom is
desired. |
|
2)
MT450 DROP CANTILEVERjib boom can be
placed at a specific height to clear
overhead
obstructions. |
|
|
|

|
MAST
TYPE JIB CRANES ADVANTAGE
|
|
|
|
ECONOMICAL |
|
Simple, efficient design that usually requires no special foundation
makes
the Mast Type Cranes the most cost effective of
the 360° rotation jib styles. |
|
|
|
EXERTS
LESS FORCE ON BUILDING STRUCTURE |
|
Exerts the least amount of force of any jib on its supporting
structure. |
|
|
|
SAFETY |
|
Utilizes a self-aligning radial bushing at the top which cannot
be displaced,
and an identical self-aligning radial bushing
at the bottom which, used in
combination with an oil-impregnated bronze
thrust washer, provides ease
of movement. |
|
|
CHART
1B - Boom Data |
|
|
Pre-Engineered for use with powered hoists. A factor of 15%
of the jib crane
capacity is allowed for the hoist and trolley
weight with an additional 25%
of the capacity allowed for impact, thus giving
maximum capacity use of the
jib. |

PRODUCTIVE |
|
Allows full utilization of the working area with 360° rotation. |
|
|
|
MAXIMUM
TROLLEY TRAVEL |
|
Mast/beam connections eliminate the need for tie rods or knee
braces found
on competitive designs, thus permitting maximum
trolley travel. |
|
|
|
OPTIONAL
POWER ROTATION |
|
(Features are shown below) |
|
|
|
|
|
 |
|
 |
|
The
diagram left details the
thrust and pull forces that the
jib crane applies to the
supporting structure when
a load is lifted. It is essential
that a structurally adequate
wall or column exists to
support the jib crane.

and pull forces. |

FEATURES
OF MOTORIZED CONTROL PACKAGE |
|
|
|
|
|
|
 |
|
|
Variable Frequency Drive (VFD) is standard. |
|
|
|
The
Variable Frequency Drive can be used in single or multiple speed
applications. |
|
|
|
|
|
|
|
Variable Frequency Drive provides the ultimate in load control.
|
|
|
|
The
VFD provides the ultimate in load control and positioning from
the
slowest possible creep speed up to maximum speed. The VFD is
up to
25 times smoother than ballast resistor controls, does not produce
extensive heat, and enables precise starting and stopping. |
|
|
|
|
|
|
|
Easily adjustable speed control. |
|
|
|
Through
a simple keypad on the VFD, the acceleration rate,
deceleration rate and rotation speed can be adjusted to fit
your application.
This allows you to customize the performance of the jib to your
exact
requirements. |
|
|
|
|
|
|
|
Designed for indoor and outdoor use. |
|
|
|
When
being used outdoors, the cranes are designed to operate in
winds of 15 mph or less, based on a maximum load surface of
16 square
feet. Consult us for applications exceeding these standards. |
The
direct drive powers the rotation
of the Free Standing Crane. A speed
of 1/2 RPM is standard. |
|
|
|
|
|
|
|
Standard NEMA 4X Controls Enclosure. |
|
|
|
 |
|
|
Standard
controls enclosure meets the requirements for NEMA 3R,
12, 4 and 4X environments. Optional enclosures are available
for other
environments. |
|
|
|
|
|
Low maintenance costs. |
|
|
The
VFD eliminates the need for magnetic reversing contractors,
reduces the number of wearable components in the panel, and
reduces
long-term maintenance costs. |
