EM/EMP SERIES 3-PHASE MINI ELECTRIC CHAIN HOISTS
EM Mini Electric Chain Hoists with Hook Suspension
The EM Series three phase mini electric chain hoists were designed with a state-of-the-art control system using Solid State Relay (SSR) technology and a microcontroller (MCU) to increase the longevity of the hoist and provide superior safety functions. These high quality, low-headroom, full-featured hoists provide reliable performance in medium- to heavy-duty industrial settings, rental and repair shops and garages.
EMP Mini Electric Chain Hoists with Push Trolley
The EM series three-phase mini electric chain hoist can be paired with our PT push trolley when you need to move material distances. This combination is ideal for workstations and occasional moves.
Features and Benefits
UL® Listed
Certified and listed to UL 1340 “Standard for Hoists” and CSA 22.2
No. 33 “Construction and Test of Electric Cranes and Hoists.”
High Performance Motor Brake
Fast acting and durable current driven electromagnetic brake.
5 year warranty.
Unique Chain Guide
Discharges chain from the side of the host body preventing tangling
when winding up slack chain. Heat treated for durability.
Forged Carbon Steel Hooks
Under excessive loads will open gradually and not fracture. Ball bearings
produce smooth rotation. Bottom hook will swivel 360°. Heavy-duty hook
latches are standard
Solid State Relay Board
Has no mechanical contacts for extended lifetime and microcontroller provides protection from fast reverse,
phase loss and reversal, overcurrent, overtemperature, and overvoltage. Includes electronic overload limiter and
an LED error indicator.
Sleek Rounded IP65 Body
Compact and rugged die-cast aluminum body with no sharp edges. Superior ingress protection makes it suitable
for both indoor and outdoor applications.
Friction Clutch
Rotor integrated friction clutch outside of the load path provides consistent performance over a
wide temperature range.
Grease-Packed Gearbox
For demanding industrial applications.
Nickel-Plated Load Chain
Grade 80, super strength load chain with superior corrosion resistance.
Chain Container
Optional black canvas chain container designed with two secure attachment points.
