metric ton lifting capacity
1. Eyebolt suspension.
Self-alignment: An eyebolt suspension is used with motorised and
plain trolleys. Unlike rigid suspensions, it allows the hoist to
pivot and align itself to the direction of the load pull, which
decreases the risk of component failure and improves load chain
and guide wear.
clutch for asset protection. The overload clutch is factory set
to limit Quantum from lifting loads in excess of 150% of rated hoisting
capacity. This protects all your assets – the hoist, your plant
structure, and, most importantly, your operator.
3. Gear case.
Smooth operation, extended service life: Double or triple-reduction
steel alloy gears are precision cut and hardened for reduced friction
and longer life. A helical/spur gear combination provides “grab
free” movement and quiet, reliable operation. Optimum lubrication:
Gears are lubricated with a semi-liquid grease instead of oil, which
is less likely to leak, eliminates oil level checks and clings to
the gears even after long idle periods. Quantum will even work upside
4. Chain guide
and wheel. Proactive alignment: A “floating” chain guide precisely
feeds chain onto a machined-matched five-pocket chain wheel. This
system insures smooth, jam resistant operation and extends load
chain, guide and wheel chain life.
load chain. Quantum load chain is precision formed from Grade 80
alloy steel, case hardened and zinc plated. The plating is an “infusion”
process, which forms a molecular bond with the alloy. The result:
premium-quality chain that attracts and retains lubrication and
resists corrosion and fatigue. Controlled elongation: Quantum chain
is engineered to elongate a minimum of 10%. This ability to stretch
reduces the possibility of catastrophic failure under sudden loading.
Any “chain chatter” is a clear indication to check and/or replace
6. Motors. High
starting torque: Quantum motors are a totally enclosed non-ventilated
(TENV) squirrel cage design. The H4 duty classification of three
phase model allows 300 starts and 30 minutes “on time” per hour.
Class F insulation allows a total thermal rating of 145°C at a 1.0
service factor, instead of the more common Class B insulation of
120°C. Quantum motors can take the heat! Phased to your needs: Single
phase motors are available as 115 or 230 volt. Because single-phase
motors are subject to low voltages that create higher motor temperatures,
these Quantum hoists are equipped with “klixons,” bimetal heat switches
that prevent motor burnout. Three phase motors are available in
230, 380, 460 and 575 volts, single and dual speeds. The 230/460
volt, single speed motors are field reconnectable. Dual speed motors
feature 4, 5, or 6 to 1 high to low speed ratios instead of the
typical 3 to 1 ratios. The advantages are unsurpassed load control,
reduced cycle time and improved productivity. The overload clutch
and Class F insulation eliminate the cost of “klixons”.
7. Brake. Metal
discs stack up against wear: Quantum has a state-of -the-art AC
motor brake employing all-steel discs. Multiple stacking significantly
increases braking surface area, reducing wear and extending life.
This system eliminates breakage common with fibre discs and the
heavier springs and DC solenoids they require. Unlike fibre discs,
steel discs create no brake dust or residue that can gum up electrical
parts and make lubricants abrasive. Quantum brake discs-guaranteed
for the life of the hoist.
controls. Safety first pendent: Quantum’s safety-first pendent control
handles are comfortable and fit securely in the operator’s hand.
Each low voltage (42 volt) control handle integrates a large, red
emergency stop button. Operating buttons are clearly marked with
high contrast arrows, feature soft push action and are horizontally
aligned for easier operation. Emergency shut-off: Activated from
the pendent handle, the mainline contactor disconnects power to
the hoist and trolley motor providing “shut-off protection” in an
emergency situation. Easy accessibility: Quantum enclosures are
weatherproof, NEMA 3R rated. Removal of just four fasteners (slot-head
on the electrical parts cover and allen-head on the mechanical parts
cover) reaches components. Since electrical and mechanical components
can be accessed separately, service is quick and clean.
9. Limit switches.
Fail-safe limits: Quantum limit levers are recessed in the hoist
enclosure. This clean, obstruction-free assembly virtually eliminates
accidental activation of switches. Upper and lower switches are
activated by the hook and endstop, eliminating time-consuming adjustments.
