How Do Electric Hoists Work?
An electric hoist operates by utilizing electrical power to lift heavy loads safely and efficiently. Firstly, the hoist is securely fixed onto a suitable anchor point, such as a jib crane or gantry crane, capable of supporting the weight of the load. Once in place, the chain or wire rope is lowered from the hoist and attached to the load, often using lifting accessories like slings to ensure even weight distribution.
With the load properly secured, the operator initiates the lift using a handheld remote control. It's crucial to pause momentarily once the load is just clear of the ground to perform a test lift, ensuring stability and security before continuing the ascent. This precaution minimizes the risk of accidents or injuries during the lifting process.
Electric hoists typically incorporate various safety features to enhance operational safety. These may include safety catches on hooks to prevent accidental disengagement, clutch systems that slip at preset torque levels to prevent overloading, and mechanisms that automatically engage the chain if the hoist is overloaded. Additionally, newer models may feature emergency cut-off switches for added safety in critical situations.
What Sets Our Electric Chain Hoists Apart?
Electric chain hoists are indispensable tools in a wide array of industries, providing powered assistance for the vertical movement of heavy loads. Cheng Day's electric chain hoists are distinguished by their exceptional functionality, safety features, and versatility, making them the preferred choice for discerning buyers.

SH D8
ELECTRIC CHAIN HOIST
Legendary in performance, professional riggers around the world have come to rely on the Black Bear SH series for the most demanding and challenging applications. This hoist is available from 250 kg to 2 ton.
SH D8+
ELECTRIC CHAIN HOIST (DIRECT TYPE)
The SH D8+ electric chain hoist, the friction clutch is not in the load path when chain hoist is disconnected from power supply. Acts as a precise overload device; and design factor is 10:1 with a double brake installed. The SH D8+ is in accordance with the VPLT Code of Practice.

VPLT.VPLT.Standard SR2.0-Special engineering requirements
- 1Bm = 400 operating hours under full load in normal use.
- Rated load = load during operation. The sum of the load plus the dynamic forces.
- A friction clutch is permitted if it is not within the load path when the electric chain hoist is disconnected from the power supply. Underload monitoring with a collective shut-down facility is required for guided loads and system loads.
- Overload shut-down/overload monitoring.
