Product Overview


The Single/Double Speed Suspended Type Heavy Duty Lifting Electric Chain Block (model: TP-EHA) is a high-performance lifting device designed by TOP LIFT INDUSTRIES CO., LIMITED, tailored for heavy duty industrial applications such as manufacturing, construction, and warehouse operations. This electric chain hoist significantly reduces operational downtime and maintenance costs, thanks to its robust structure and low-upkeep design. It can effortlessly handle loads ranging from 500kg to 5000kg, making it ideal for both light and heavy lifting tasks.


As a CE certified electric chain hoist, it meets international safety and quality standards, ensuring compliance in global markets. The hoist supports both single-phase and three-phase power supplies, offering flexibility for diverse industrial setups. Additionally, its IP54 dust-proof & water-proof protection enables stable operation in harsh environments—whether dusty workshops or damp outdoor areas. For brands seeking personalized solutions, TOPLIFT OEM service is available, allowing custom logos and specifications to match brand identities.


Product Appearance


The TP-EHA electric chain block features a compact, space-saving design that excels in areas with limited headroom. Its key visual and functional components include:

FEC JAPAN load chain: A high-strength, corrosion-resistant chain that is visible along the hoist’s core, ensuring durability and smooth lifting.

24V safety push button: A ergonomic, low-voltage controller located on a handheld pendant, designed for safe operation and to prevent electrical hazards.

High-tensile safety hooks: Heavy-duty hooks at the top (suspension) and bottom (load) with a sleek, industrial finish—these hooks are tested to withstand extreme tension without breaking.

Dust-proof & water-proof casing: A rugged metal enclosure that covers the motor and electrical components, marked with the TP-EHA model and CE certification for easy identification.

Compact motor housing: A streamlined motor unit that reduces the hoist’s overall size, making it easy to install in tight spaces like factory ceilings or narrow workstations.

Mechanism Design


The TP-EHA electric chain block’s mechanism is engineered for efficiency, safety, and long-term use, with core design features including:


High-Efficiency Motor System

A high-efficiency motor with heat protection forms the heart of the hoist. The motor’s thermal protection device prevents overheating during prolonged use—critical for long working hours in industrial settings. It operates quietly and consumes less energy compared to traditional pneumatic or manual hoists, aligning with energy-saving goals.


Safety Limiting Devices

Two key safety mechanisms reduce accident risks:

Limit switch: Stops the hoist when the load reaches maximum or minimum lifting height, preventing chain overstretching or motor damage.

Limit load device: Shuts down the motor if the load exceeds the rated capacity, protecting both the hoist and the lifted goods.


Smooth Transmission System

The hoist uses a precision gearbox that connects the motor to the FEC JAPAN load chain. This transmission system ensures smooth, consistent lifting speeds (single or double) and minimizes wear, extending the chain’s lifespan. For double-speed variants, a dual-gear setup allows operators to switch between fast (for quick positioning) and slow (for precise placement) modes.


Tensile Hook Design

The high-tensile safety hooks are forged from high-grade steel and undergo rigorous testing to withstand 1.5 times the rated load. Their open-and-close latch design ensures the load stays secure during lifting, even in unstable conditions.


Standard Parts


Every TP-EHA Single/Double Speed Suspended Type Heavy Duty Lifting Electric Chain Block comes with pre-installed standard parts that meet global quality standards. These parts include:


Core Functional Parts

FEC JAPAN load chain: High-strength, wear-resistant chain (7.1mm diameter) for reliable load bearing.

24V push button controller: Low-voltage pendant with easy-to-use up/down/speed buttons, ensuring operator safety.

High-tensile safety hook set: One top suspension hook (for mounting) and one bottom load hook (for securing goods).


Protective & Auxiliary Parts

IP54 electrical enclosure: Sealed casing for electrical components, blocking dust and water splashes.

Heat-protected motor cover: A metal shield that insulates the motor and prevents contact with hot surfaces.

Load chain guide: A plastic or metal guide that keeps the chain aligned during lifting, reducing friction and noise.


Documentation & Certifications

Each unit includes a CE certification document, user manual (with installation and maintenance guidelines), and a part list for future replacements—supporting easy setup and after-sales service.


The Single/Double Speed Suspended Type Heavy Duty Lifting Electric Chain Block (TP-EHA model) combines durability, safety, and flexibility, making it a top choice for industrial lifting. Whether for OEM projects or direct purchases, TOPLIFT ensures consistent quality and global compliance.
