Specifications -
- The crane structure is manufactured from
material according to IS
2062. Designed to withstanding all imposed loadings, with a maximum deflection of
1/750th of the span.
- The crane
is driven by a matching pair of
braked motors the drive
being transmitted through a direct, live axle, maintenance free, gear box via
hardened and ground helical gears in a sealed oil bath. Operation is via a single
reversing contactor type controller, with an automatic slow to fast speed timing
device to provide smooth acceleration and a balanced tandem operation with no
skidding or crabbing of the crane in any load permutation.
- A 600mm
wide access walkway with gate is
provided along one girder.
(Double girder cranes only).
- The
proprietary series built, hoist unit
would be selected from our
extensive range of units which have a world wide reputation for reliability, modern
design, safety and the very latest manufacturing techniques. The modular design
forms a very efficient, compact & visually aesthetic unit. The hoist
transmission
train is a direct drive type with no coupling. The rope drum is mounted in
maintenance free bearings. Located within the hoist bearer frame. The drum is
accurately machine grooved to accommodate the hoisting rope in one layer. And is
designed to leave a minimum of 3 (three) turns on the drum when maximum lift height
is reached.
- A rope
guide is provided to prevent slack
rope and to smoothly guide
the rope onto the drum. The rope is securely attached to the drum with 3 (three)
rope clips.
- The bottom
hook block is of the safety
type, having fully guarded
deep grooved sheaves, running in sealed ball bearings. The hook is a forged steel
single point "C" Type, mounted on a ball thrust race and fitted with a spring return
safety catch.
- The special
non-rotating hoist rope is
manufactured from high
strength galvanised steel, the standard construction is 6x36+SES with a minimum
factor of safety of 5:1. Over-hoist/over-lower limit switches, are provided located
within the hoist control panel. The electromechanical overload devise prevents the
accidental lifting of loads over the safe working load whilst still allowing
lowering.
- The Hoist
&
Travel drive motors with
integral brake are totally
enclosed, fan cooled, squirrel cage induction type, having class "F" insulation with
"B" temperature rise, tropicalised and climate proof with a minimum electrical
protection of IP55. The motors are specifically designed for crane applications for
use in aggressive environments, without the need for anti condensation heaters.
- The heavy
duty totally enclosed, fail
safe, disc brakes are
automatically and instantaneously applied when the power supply is interrupted.
Brake linings are asbestos free. Electrical control of the complete crane would be
from floor level via a heavy duty, weatherproof pendant control station fully mobile
across the crane span to allow operation of the crane at a safe distance from the
load.
- Galvanised
tension relief cables to
prevent damage to the electrical
connections support the pendant. Robust hold-to-run, control buttons, one for each
crane function, provide positive operation of all motions. An Emergency stop Button
is also provided.
- A
watertight control panel would be
mounted at one end of the crane
bridge containing the complete control systems, comprising. A pair of electrically
and mechanically linked contactors for each crane motion.
- Main and
control circuit fuses, control
circuit transformer c/w the
necessary protection devices to provide reduced operation of the control circuits.
The contactors are AC 4 duty for high inching & plugging duty.
- A main
current supply system, would
provide the power supply along
the length of the runway. Consisting off a special galvanised 'C' type track systems
with sealed ball bearing cable trolley's carrying special flat Neoprene cables type
NYNJ. All necessary fittings and supporting brackets to connect to the runway are
provided.
- A high
level terminal box would be
provided at one end of the system,
together with the necessary vertical cable, terminating in a low level, lockable
Isolator switch, for mounting 1500 mm above grade, complete with a suitable gland to
accept your incoming supply cable.
- Prior to
packing & protected for
transportation, the crane would
be assembled in our workshops & fully inspected & tested, according to our
standard testing procedure, which would include full dimensional and functional
tests of all crane operations including limit switches.
