• Easy trolley mounting attachment meets various application requirements. Slot in top 
  of hoist body allows easy changeover of top hook, push trolley or motorized trolley mountings.
• Crown tread wheels standard on push and motorized trolleys, for use on standard 
  I-beams and wide flange beams.
• Plug-in push button pendant with E-stop for quick replacement is standard.

* Hoist gearboxes: LM1: AGMA 10, LM05 & LM10: AGMA11 and LM16/25: AGMA 12.
   Traveling gearboxes: AGMA 10.

REDUCED MAINTENANCE
Quality keeps your hoists on the job long past the pay-off point

LoadMate^® hoists are designed to run cool and maximize the life of gears, brakes and motors. 
Longer hoist component life means less maintenance, less downtime and lower repair costs.

• Sealed brake keeps out lubricants.
• The hoist brake and load limiter are both adjustable and adjust independently of each other.

SAFETY Meets or exceeds industry safety standards All R&M electric chain hoists are statically and dynamically tested with a minimum of 125% rated load prior to shipping. All hoist models are equipped with a torque-limiting device for hoist overload protection. The electromagnetic disc brake-clutch combination is designed for efficiency, safety, easy access and adjustment. The friction-type torque limiter is integrated with the brake (LM1, LM05, LM10) to ensure that the load is always stopped when the control button is released. Upper / lower limit switches stop the hoisting motion when the hook reaches the top or bottom limit of travel, providing safer operation and longer equipment life. Low-voltage controls enhance operator safety. 115-volt control voltage is standard; 48-volt control is an option (standard with 380 volt) for all electric chain hoists. Hoist control panel and pushbutton enclosures both meet NEMA type 3R (IP-55) protection classification. Load hook is forged alloy steel for strength and durability and is provided with a spring return safety latch. Emergency stop button and built-in mainline contactor are standard. (Except LM1.) CSA certification on all models.
LONG LIFE Built for tough duty and lasting performance Every feature of the LoadMate® hoist assembly includes rugged, high-performance materials and quality engineering for longer service life and less downtime. Thermal protection of hoisting motor prevents damage due to over heating. A 2-speed hoist motor is available, offering more precise load handling and longer motor life due to less wear on the brake and contactor. Hoist body is constructed of pressure-cast aluminum for light-weight and easy handling, epoxy-painted for corrosion resistance, and ribbed for better heat dissipation. 5-pocket chain sprocket (6-pocket on LM16) is heat-treated and machined to a high tolerance, providing exceptionally smooth lifting and reduced chain wear. Load chain is electro-zinc plated, heat-treated, and has a high tensile strength. Chain is also specially designed for chain hoist use. Chain guide ensures precise alignment of chain with load sprocket, reducing wear and prolonging chain life. Chain container for hoist is provided as standard.	Push Button with E-stop
ADDED VERSATILITY Variable Frequency Drive option enhances motorized trolley operation TMU's Variable Frequency Drive offers: 2-step multi-speed or stepless control method Flexibility in speed settings Dynamic braking Minimum and maximum speed settings can be defined to provide easy and precise load placement, reduced load swings and less wear on equipment. The sealed brake is incorporated into the motor design. The dynamic braking provided by the variable frequency drive allows for smooth stops and extended brake life.
