SEM/SEMP SERIES SINGLE PHASE MINI ELECTRIC CHAIN HOISTS

SEM003L

SEM Mini Electric Chain Hoists with Hook Suspension

The SEM series single phase mini electric chain hoists are designed for areas that offer only single phase power. Built for durability and safety with 
Solid State Relay (SSR) technology and a microcontroller unit (MCU), this hoist delivers reliable operation in places with limited space.

SEMP Mini Electric Chain Hoists with Push Trolley

The SEM Series single-phase mini electric chain hoist can be paired with our PT push trolley to transport material from one location to another. This combination is the best choice for work that requires infrequent moves in an 
area that has single phase power available.

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

SEMP003L

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.
