As a Master Distributor
for R&M, there is a wide variety of hoists available
from electric / manual chain hoists up to 5 ton capacities
and wire rope hoists up to standard 20 ton lifting capacities.
Larger sizes can be custom built.
For electric wire rope applications,
standard configurations include normal headroom, low
headroom and double girder trolley designs. Three hoist
frame sizes (in both short ton and metric ratings) are
available to meet a variety of application requirements:
· ½ ton - 10 ton (500
- 10,000 kg) capacities
· 19'8" - 78'8" (5.9 - 24m) heights
· Lift speeds 20/3 - 62/10 fpm
· 2.9 - 24 HP (2.2 - 18.0 kw) hoist models
· 208, 230, 460, 575/3/60 or 380/3/50 supply
An innovative design that includes a large drum diameter
gives Spacemaster SX hoists the lowest headroom and
best wheel loads in the industry, while providing near
true vertical lift, with exceptional hook approaches
and heights of lift.
Unique features include new maintenance-free,
lifetime-adjusted, sealed brakes; a two-speed hoist
motor; and trolley inverter control. A NEMA 4 control
enclosure is also standard. Spacemaster SX hoists are
designed to meet and exceed ASME H4 duty (FEM 2m &
3m) ratings and provide the ultimate in easy load handling,
safe operation and lasting, trouble-free performance.
Ease of Operation
Large-diameter hoist drum means easy
positioning, closer approaches.
The larger rope drum diameter provides nearly true vertical
lift with a single reeved hoist -- only 1/8" drift
per foot of lift. The result is exceptionally smooth
movement and fast load positioning. This innovative
design also means a shorter frame length, allowing closer
Hoist and trolley motors designed for
space savings and productivity.
Standard two-speed hoist motor (6:1 ratio), designed
specifically for hoisting applications, offers high
starting torque and ensures precise and reliable load
This motor is class F insulated, 30
minute rated (60% effective duty), thermally protected
and totally enclosed.
The trolley motor's standard inverter
control offers two-step or infinitely variable speed
control for smooth acceleration and deceleration; minimal
load swing; fast, efficient handling; and accurate load
Safety features others don't offer--or
offer at extra cost--are standard.
An electromechanical load limit switch prevents the
lifting of loads that are in excess of 110% of rated
capacity. The 4-position hoist limit switch includes
a new phase mismatch protection circuit that prevents
the block from running up and damaging the hoist in
the event of phase reversal.
Durable, lifetime-rated, adjustment-free
brakes, hardened ground gears, thermal motor protection,
exceptional rope life and ergonomic hook block design
with sturdy safety latch contribute to the hoist's safe
operation and increased reliability.
Innovative gearbox provides dependable
operation and extends equipment life.
The innovative gear case design reduces
stress on drum bearings, reducing the need for maintenance
while extending component life. It features hardened
and ground internal reduction gears driving an external
drum gear located on the inner surface of the rope drum.
The gearbox's semi-fluid grease lubrication also helps
to extend its working life. With no load brake, the
gear case runs cooler and more efficiently.
Larger hoist drum minimizes rope
wear and enhances cooling.
A drum/rope diameter ratio of approximately 40:1 minimizes
rope flex, reducing wear and extending rope life. The
drum's large capacity also contributes to a reduction
in frame size and weight, reducing wear on hoist components
and enabling the use of more cost-effective crane girders.
The unique placement of the hoist motor inside the drum
provides directed airflow through the drum for optimal
motor cooling. This design also makes the motor and
brake more easily accessible.
