The Spacemaster® SX Electric Wire Rope Hoists from R&M Materials Handling represents a revolutionary new generation of exceptionally reliable electric wire rope hoists, featuring advanced technology and cutting-edge performance.
An innovative design that includes a large drum diameter gives Spacemaster® SX hoists the lowest headrooms and best wheel loads in the industry while providing near true vertical lift with single reeved hoists, and both exceptional hook approaches and heights of lift.
Advantages:
- New low maintenance, sealed brakes, a two-speed hoist motor, and trolley inverter control.
- Standard hoist nameplate will carry a CSA c/us rating as well as a NEMA 3R rating for electrical enclosures.
- Two-component epoxy paint is standard.
- Designed to meet and exceed either ASME H3 or ASME H4 duty (FEM 1Am, 2m, or 3m) ratings.
- Provides the ultimate in easy load handling, safe operation and lasting, trouble-free performance.
Standard electric wire rope hoist configurations include normal headroom, low headroom and double girder trolley designs. Hoists in short ton ratings (ASME) or metric ratings (FEM) meet a wide variety of application requirements:
- 1/2 - 80 ton (500 - 80,000 kg) capacities.
- Lifts starting at 13ft (4m) to 320ft (100m) and beyond
- Lifting speed range 10/1.5 to 62/10 fpm (3/0.5 - 19/3 m/min)
- 208, 230, 460, 575/3/60 or 380/3/50 power supply
- Single-reeved or double-reeved.
EASE OF OPERATION
- Large-diameter hoist drum means easy positioning, closer approaches.
- Larger drum diameter provides near true vertical lift with a single reeved hoist — only 1/8" drift per foot of lift.
- Exceptionally smooth movement and fast load positioning.
- Innovative design also means a shorter frame length, allowing closer end approaches.
- Hoist and trolley motors designed for space savings and productivity.
- Standard two-speed hoist motor (6:1 ratio), designed specifically for hoisting applications.
- Hoist motor is class F insulated, 30 minute rated (60% effective duty), thermally protected and totally enclosed.
- Trolley motor's standard inverter control offers two-speed multi-step or infinitely variable speed control for smooth acceleration and deceleration.
- Minimal load swing, fast, efficient handling and accurate load placement.
SAFETY
- Electromechanical load limit switch prevents the lifting of loads that are in excess of 110% of rated capacity.
- 4-position hoist limit switch includes an innovative phase mismatch protection circuit.
- Sealed brakes, hardened ground gears, thermal motor protection, exceptional rope life and ergonomic hook block design with sturdy safety latch.
LESS MAINTENANCE
- Sealed brakes mean long-term value.
- Sealed dust-proof brakes on the trolley.
- Trolley design reduces wear on components.
- Hoist motors require little adjustment for over a million cycles and will last the life of the hoist under normal use.
- Trolley drive is totally enclosed, grease lubricated and is designed to be maintenance-free.
- Trolley wheel bearings are permanently lubricated.
- Automatic disc brake and inverter control help extend the life of the motor and other components.
- Less maintenance, less downtime, lower repair costs – and reduced cost over the lifetime of your hoist equipment.
LONG LIFE
- Innovative gearbox provides dependable operation and extends equipment life.
- Innovative gear case design reduces stress on drum bearings.
- Hardened and ground internal reduction gears driving an external drum gear located on the inner surface of the rope drum.
- Gearbox's semi-fluid grease lubrication also helps to extend its working life.
- Gear case is designed to run cooler and more efficiently than those equipped with a mechanical load brake.
- Larger hoist drum minimizes rope wear and enhances cooling.
- Drum/rope diameter ratio of approximately 40:1 minimizes rope flex.
- Drum's large diameter also contributes to a reduction in frame size and weight.
- Unique placement of the hoist motor inside the drum provides directed airflow through the drum for optimal motor cooling.
