HsHd-Type European Standard Wire Rope Electric Hoist; HsHd-Type New-Style Electric Hoist

Low-clearance design: Featuring a compact enclosure design, the hoist body is 30–50% shorter than the traditional CD1 model, allowing for greater effective lifting height under the same factory ceiling clearance. It is particularly suitable for retrofitting low-ceilinged factories and optimizing ceiling clearance in new factory buildings.

Core components imported from Germany: The hoisting motor and gear reducer are manufactured by the German brand ABM, with an IP55 protection rating and Class F/H insulation. Operating noise is ≤70 dB(A), significantly lower than the ≤80 dB(A) of traditional hoists, thereby improving the workshop working environment.

Two-speed + Inverter Speed Control: The hoisting speed is adjustable with two speeds (fast-to-slow ratio of 5:0.8 to 3:0.5), and the travel speed is variable from 5 to 20 m/min via a variable-frequency drive. Starting and stopping are smooth and shock-free, meeting the dual requirements of precision equipment hoisting and efficient material handling.

Dual Braking Safety System: Equipped with dual brakes (self-brake + safety brake) as standard, providing an additional layer of safety redundancy compared to the traditional CD1-type single-cone brake, ensuring that heavy loads can be reliably suspended in the air.

Long maintenance cycle: Maintenance interval of 1,000 hours (compared to 500 hours for the traditional CD1 model), with a long maintenance-free period that reduces total cost of ownership over the product’s lifecycle. Dual electronic and mechanical limit switches ensure precision and reliability.

The operating principle of the HsHd-type European-style electric hoist is based on a compact, enclosed hoisting mechanism combined with an FEM-optimized transmission design:

① Hoisting Drive: The German ABM hoist motor is directly connected to the gear reducer via a flange, eliminating the spline sleeve and coupling found in traditional CD1 models, resulting in a shorter power transmission path and higher efficiency. When the motor is energized, it drives a three-stage helical gear reducer, which ultimately drives the drum to rotate.

② Two-speed switching: Two-speed hoisting is achieved by commutating the motor windings—the high speed (5–12 m/min) is used for rapid lifting and lowering of an empty hook and for long-distance transport, while the low speed (0.5–1.2 m/min) is used for precision positioning and installation work; the transition between speeds is smooth and shock-free.

③ Variable-frequency operation: The drive motor uses variable-frequency speed control, providing stepless speed adjustment within the range of 0–20 m/min, ensuring smooth starts and stops and minimizing swaying of the load. The variable-frequency drive is built into the control cabinet, reducing the need for external wiring.

④ Dual-Brake Principle: The motor is equipped with a built-in tapered rotor brake (first-stage braking), and a safety disc brake is installed on the high-speed shaft end of the reducer (second-stage braking). When power to the motor is cut off, both braking systems engage simultaneously, with a braking response time of ≤0.2 s.

The HsHd-type European-style electric hoist consists of the following core components:

ABM Hoist Motors (Germany): Imported brand, tapered-rotor braked asynchronous motor (two-speed), protection rating IP55, insulation class F/H. Equipped with a cooling fan and thermal protection device.

ABM Gearboxes from Germany: Three-stage helical gear reduction; gears undergo carburizing and quenching followed by gear grinding, with a precision grade of 6. The housing is made of high-strength cast iron, with an IP55 protection rating.

Reel Assembly: Made of high-strength steel plate that is rolled and welded into shape, the drum grooves are precision-machined to guide the steel wire rope into an orderly arrangement. The drum diameter has been optimized; despite being smaller than that of the traditional CD1 model, it provides a greater lifting height.

Steel Wire Rope: Anti-rotation wire ropes (35×7 or 18×7 construction) are used to reduce hook rotation and twisting. The wire rope has a safety factor of ≥5 (FEM standard).

Hook Assembly: Forged hook with smooth rotation and a safety latch. The hook is made of forged and normalized material, with a safety factor of ≥4.

Safety Brake: Disc-type safety brake on the high-speed shaft end of the reducer, spring-applied and electromagnetically released, with a braking torque of ≥1.5 times the rated torque.

Control Box: IP55 protection rating, with built-in inverter, contactor, electronic limit switch, and mechanical flame-out limit switch for dual protection.

Push-button Switch: It can be operated using either a wired controller or a wireless remote.

Precision Manufacturing Workshop: The two-speed + variable-frequency control ensures smooth starting and stopping, and, when paired with a European-style overhead crane, meets high-precision lifting requirements such as precision machine tool assembly and mold replacement.

Automobile Assembly Line: The low-head design is suitable for compact factory buildings, and the German ABM motors operate quietly (≤70 dB(A)), making them ideal for modern production lines that require low noise levels.

Food Processing/Pharmaceutical Production Facilities: IP55 high protection rating, dustproof and waterproof, suitable for cleanrooms.

Logistics and Warehousing: Lifting speed of 5–12 m/min for fast, high-efficiency material handling; variable-frequency operation ensures smooth movement and reduces cargo sway, thereby improving warehouse operation efficiency.

Renovation of Old Factory Buildings: With its low headroom and lightweight design, this solution provides greater lifting height and load capacity without requiring structural modifications to the factory building, making it an ideal choice for factory upgrades and renovations.

Working Conditions: Ambient temperature: -20°C to +40°C; relative humidity: ≤85%; altitude: ≤1000 m. Power supply: three-phase 380 V/50 Hz. Not suitable for use in environments with explosive or corrosive media, or for hoisting molten metal.

Pre-Operation Checks: Check the wire rope for broken strands, wear, and kinks (the safety factor for European-style hoist wire ropes must be ≥5); check whether the dual brakes are operating normally; check whether the variable frequency drive panel display is normal; confirm that the limit switches are sensitive and reliable.

Operating Procedures: Before lifting, verify that the load does not exceed the rated capacity; use the low-speed setting for precise positioning and installation; use a variable-frequency drive to ensure smooth acceleration and deceleration, avoiding load sway caused by rapid starts and stops; do not lift loads at an angle or in a skewed manner, and do not allow loads to pass over personnel.

Maintenance: Maintenance interval of 1,000 hours (approximately 6 months of normal use), which is significantly longer than the 500-hour interval of the traditional CD1 model. Check the condition of the reducer lubricant every 1,000 hours and replace the gear oil every 2,000 hours. Check the brake wear every 500 hours (disc brake pad thickness ≥ 3 mm). For the electrical components, clean the inverter heat sink quarterly.

German Technology + Domestic Costs: The core components of the HsHd European-style electric hoist feature German ABM lifting motors and gearboxes (imported). The frame is designed and manufactured in-house, and the entire unit is assembled on-site. Its performance matches that of imported electric hoists, yet it costs only 60–70% of the price of fully imported products (%).

Experts in Low-Clearance Solutions: The compact enclosure structure, designed in-house, reduces the height of the hoist body by 30–50%, allowing for a greater effective lifting height under the same factory ceiling clearance. We have provided European-style low-clearance solutions for numerous retrofit projects involving older factory buildings, enhancing lifting capacity without the need for new construction.

End-to-End European-Style Quality Control: From the inspection of motors imported from ABM in Germany and individual run-in tests of gear reducers to full-load commissioning of the complete unit, the entire process is conducted in accordance with FEM standards. Each HsHd hoist undergoes a 2-hour full-load test before leaving the factory, and key data—such as braking distance, noise level, and temperature rise—are recorded and archived.

Q: What is the difference between the HsHd European-style electric hoist and the traditional CD1-type electric hoist?

Answer: The HsHd European-style electric hoist is designed in accordance with the FEM European standard. The main differences from the CD1 model are: ① Low headroom design (hoist height is 30–50% lower); ② 20–30% lighter self-weight (1TP–3T); ③ Core components imported from ABM, Germany; ④ Dual-brake safety system (CD1 type has a single brake); ⑤ Operating noise ≤70 dB(A) (CD1 type ≤80 dB(A)); ⑥ Maintenance interval of 1,000 hours (CD1 type: 500 hours); ⑦ Protection rating IP55 (CD1 type: IP44). In terms of price, the HsHd model is approximately 1.5–2 times the price of the CD1 type for the same tonnage.

Q: What standards do HsHd European-style electric hoists comply with? Are the core components imported?

Answer: The HsHd series of European-style electric hoists comply with FEM (European Federation of Material Handling) standards, as well as the requirements of GB/T 3811 “Code for Design of Cranes” and JB/T 9008.1 “Wire Rope Electric Hoists.” Key Components: The hoisting motor and gear reducer are imported from the German brand ABM, while structural components such as the frame, drum, and hook assembly are designed and manufactured in-house. The entire unit is assembled in China, and we can provide certificates of origin and customs declaration forms for the imported components.

Q: What is the approximate price of the HsHd European-style electric hoist?

Answer: The HsHd European-style electric hoist is priced higher than the traditional CD1 model of the same tonnage because it contains a high proportion of imported core components (German ABM motor and gear reducer). Approximate price ranges: 1–3.2 metric tons: approximately 6,000–15,000 yuan; 5–10 metric tons: approximately 15,000–30,000 yuan; 16–20 metric tons: approximately 28,000–60,000 yuan. If you require configurations such as a variable-frequency control system, wireless remote control, or non-standard lifting heights, the price will be calculated separately based on your customization needs.
