CD1/MD1 Hoist Model Parameters at a Glance
The core parameters of the CD1 single-speed and MD1 two-speed wire rope electric hoists are compared below. The CD1 covers lifting capacities from 0.5 to 20 t (standard range 1–20 t), while the MD1 standard range is 1–20 t. Lifting heights for all capacities can be selected from 6 to 30 m. The CD1 offers a lifting speed of 8 m/min (7 m/min for hoists above 10 t), while the MD1 provides two-speed hoisting at 8/0.8 m/min (7/0.7 m/min above 10 t). Travel speed for both models is 20 m/min. CD1-0.5t: wire rope diameter 5.1 mm / motor 0.8 kW / dead weight 120 kg, CD1-1t: 7.4 mm / 1.5 kW / 155 kg, CD1-2t: 8.7 mm / 3.0 kW / 235 kg, CD1-3t: 11.0 mm / 4.5 kW / 310 kg, CD1-5t: 13.0 mm / 7.5 kW / 525 kg, CD1-10t: 15.0 mm / 13 kW / 1,010 kg, CD1-16t: 17.5 mm / 18.5 kW / 780 kg.
At the same capacity, the MD1 uses a two-speed motor configuration (fast/slow power ratings) and has a slightly higher dead weight than the CD1: MD1-1t: 1.5/0.2 kW / 185 kg, MD1-2t: 3.0/0.4 kW / 265 kg, MD1-3t: 4.5/0.4 kW / 350 kg, MD1-5t: 7.5/0.8 kW / 580 kg, MD1-10t: 13/1.5 kW / 1,080 kg.
CD1 vs. MD1 Price Reference and Cost Factors
Electric hoist pricing is influenced by lifting capacity, lifting height, whether a remote control is included, special voltage requirements (e.g., 380V/220V/440V/660V), explosion-proof construction, and two-speed configuration. The following are Kelude's reference price ranges for a single CD1/MD1 wire rope electric hoist (excluding the trolley): CD1-1t approx. $450–$900, CD1-2t approx. $600–$1,200, CD1-3t approx. $740–$1,500, CD1-5t approx. $1,200–$2,200, CD1-10t approx. $2,200–$4,500, CD1-16t approx. $3,700–$7,400, CD1-20t approx. $5,200–$10,400. The MD1, with its two-speed motor and electrical system, costs 20–30% more than the CD1 at the same capacity. A complete set including the electric trolley travel mechanism adds approximately 15–25% to the base price. Adding a remote control (e.g., F21 series) costs an additional $75–$300.
Under China's Special Equipment Catalog (State Administration for Market Regulation Announcement No. 57 of 2020), a CD1/MD1 electric hoist sold or used as a standalone unit is not classified as special equipment and does not require inspection. However, when the hoist is mounted on an overhead crane or gantry crane with a rated lifting capacity of ≥3 t, the complete crane must be managed as special equipment and must undergo installation supervision inspection and obtain a use registration certificate. Kelude provides a complete Factory Acceptance Test Report and installation documentation upon delivery to assist users with the inspection application process.
Structural Differences: CD1 Single-Speed vs. MD1 Two-Speed
The CD1 uses a single-speed conical-rotor brake asynchronous motor with one rated power and one output speed. When the hoisting motor starts, the conical rotor moves axially under electromagnetic force, compressing a spring to generate braking torque—this is the conical-rotor braking principle. Its advantages are an extremely simple structure (no independent brake), low cost, and easy maintenance. The drawback is that hoisting is limited to a single speed, making precision positioning more difficult.
The MD1 adds a slow-speed winding to the CD1 design, creating a two-speed conical-rotor brake asynchronous motor. The fast-to-slow speed ratio is fixed at 8:0.8 (7:0.7 for hoists above 10 t), with the slow speed at approximately one-tenth of the fast speed. Operators can use the fast speed for rapid lifting of no-load or light loads, then switch to slow speed for precise positioning as the load approaches its target—significantly improving safety and operating accuracy during installation work. The MD1's motor size and dead weight are approximately 10–20% greater than the CD1 at the same capacity, and the electrical control system requires a two-speed contactor or VFD.
Application Scenarios and Selection Recommendations
CD1 single-speed applications: Routine material handling in factory workshops, warehouse loading and unloading, production line loading and unloading, occasional dock lifting, and power station equipment maintenance. Ideal for general-purpose use where precision positioning is not required and where economy and maintenance convenience are priorities. The CD1-0.5t to 5t models suit light-duty conditions, while the CD1-10t to 20t models handle medium-capacity routine lifting. The CD1 is the most cost-effective wire rope electric hoist option.
MD1 two-speed applications: Machinery installation and alignment (positioning accuracy within ±5 mm), mold changes, precision assembly stations, steel structure erection and splicing, and maintenance work requiring accurate load placement. The MD1 costs 20–30% more than the CD1, but the time saved and reduced risk of load collision more than justify the price difference. If budget allows or positioning accuracy is critical, the MD1 is the recommended choice.
Selection recommendations: ① Select the rated lifting capacity based on the heaviest load to be lifted (a 15–20% margin is recommended). ② Determine the lifting height based on workshop height and application needs (standard heights: 6 m, 9 m, 12 m; special heights up to 30 m). ③ Verify I-beam compatibility with the crane rail type (e.g., CD1-1t fits I20a-56b, CD1-5t fits I25a-63c). ④ The CD1/MD1 hoists are most commonly paired with MH-type single-girder gantry cranes or LD-type single-girder electric overhead cranes. ⑤ For use on the main girder of a large-span overhead crane, a complete package with an electric trolley is required.
