Product Overview

This crane features a lightweight design, higher lifting capacity, and an optimized structure for enhanced performance.
Model Overview:
CD1 Electric Hoist: Offers single-speed operation for general lifting applications.
MD1 Electric Hoist: Provides dual-speed control (normal and low), enabling precise tasks such as fine loading, sandbox molding, and machine maintenance, making it suitable for a wider range of uses.
HC Series: For heavier lifting demands, we produce large-tonnage electric hoists such as the HC type.
General Features:
The CD/MD series electric hoist is a compact and lightweight lifting solution known for its robust construction, small footprint, and easy operation. Key advantages include:
High mechanical efficiency and extended service life when equipped with a hardened gear surface reducer.
Conical rotor brake motors with integrated upper and lower safety limiters.
Stable and accurate lifting, especially with the MD type’s dual-speed control.
Modular design for easy access, disassembly, and maintenance, minimizing downtime.
Key Components:
Motor: High-torque conical rotor brake motor (supplied by Nanjing Special Motor Factory), capable of frequent starts with a maximum torque 2.4–3 times the rated value.
Gear Box: Features specially treated, wear-resistant gears and ball/roller bearings for smooth, low-friction operation.
Wire Rope: Complies with export standards, with a safety factor of 6 based on nominal breaking strength.
Rope Drum: Grooved, seamless drum that winds rope in a single layer to minimize abrasion, supported by ball bearings.
Control System: Includes contactor box, control switch, and limiters, operating at 380V, 36V, or 24V (safety voltage).
Rope Guide: Reinforced two-part design fully enclosing the drum to prevent uncoiling.
Hook: Tested to 150% of full load; sheaves are guarded and run on ball bearings, with thickened, durable pulleys.
Customization & Special Applications:
We can also produce customized wire rope hoists with capacities up to 16–20 tons, lifting heights of 30–100+ meters, and configurations such as single/double drums or hooks. Modifications to motor voltage are available per client requirements.
Explosion-Proof Models:
For hazardous environments where explosive mixtures may be present, we offer explosion-proof electric hoists. These feature:
Wire ropes and components made of aluminum bronze, beryllium bronze, or H62 copper alloy.
Gears treated for high temperature and wear resistance.
Compact, lightweight design with low pulling force, suitable for chemical, marine, and other flammable or explosive settings.

Application Scenario

The HB type flame-proof hoist is designed for operation in hazardous environments containing combustible materials and explosive dust, ensuring safety in high-risk industrial applications.

Standard Models: CD1 & MD1 Wire Rope Electric Hoists
These compact and versatile hoists are widely used to improve efficiency and working conditions across various sectors, including factories, mines, harbors, warehouses, cargo storage areas, and shops. They can be installed on single beam, bridge, gantry, and arm cranes, and with slight modification, can also function as winches. Specifically, the CD1 model offers single-speed operation, while the MD1 model provides both normal and low speeds for more precise handling tasks.

Flexible Installation & Integration
CD and MD type hoists can be mounted on straight or curved I-beam tracks of single-girder cranes. They are also commonly integrated with double-girder gantry cranes and slewing cranes, making them a prevalent lifting solution in industrial and mining enterprises, railways, wharfs, and storage facilities.

Explosion-Proof Electric Hoist Applications
The explosion-proof electric hoist serves as a portable manual lifting device, often paired with an explosion-proof manual monorail trolley to form a complete lifting and transport system. It is essential in high-risk environments such as petroleum, petrochemical, chemical, power, mining, electronics, and railway facilities, where flammable or explosive atmospheres may be present.

Safety Design
These hoists are engineered to prevent mechanical sparks from friction or impact during operation, significantly reducing the risk of fire and explosion. This ensures the protection of both personnel and assets, making them a critical tool for equipment manufacturing and maintenance in hazardous conditions.
