5t Electric Hoist Technical Parameters & Selection Guide
The 5t electric hoist is the most commonly used lifting device in industrial factory buildings. It features a 13mm wire rope diameter, operates on I-Beam rails from 25a to 63c, and is powered by a 7.5kW motor (CD1 model) or a 7.5+0.8kW motor (MD1 model). The reference price for the CD1 model ranges from $560 to $810. This article provides a complete parameter guide across five key dimensions—wire rope specifications, I-Beam selection, motor power, installation wiring, and price comparison—to help procurement and engineering professionals quickly access the critical data needed for proper hoist selection.
5t Electric Hoist Specifications & Key Parameters
The 5t electric hoist is the most widely used capacity class in industrial applications, commonly found in factory hoisting, warehouse loading/unloading, equipment installation, and maintenance operations. Per the JB/T 9008.1-2014 standard, the main configurations for a 5t electric hoist include: the CD1 single-speed model (lifting speed 8m/min), the MD1 two-speed model (8/0.8m/min), and the HC series square box hoist (VFD/multi-speed adjustable). When selecting a hoist, key factors to evaluate include wire rope diameter and length, I-Beam rail size, motor power, power supply requirements, work duty classification, and budget. Below is a comprehensive parameter comparison and selection guide organized across five critical dimensions.

5t Electric Hoist Wire Rope Specifications
Key parameters for 5t electric hoist wire rope selection: CD1 models use 13mm wire rope, MD1 models also use 13mm, with a 6×37+FC multi-strand fine-wire construction. Nominal tensile strength is 1670MPa, with a safety factor per ISO 4301 Crane Design Standard of ≥5 (M4) or ≥5.6 (M5). Wire rope length is calculated by lifting height × pulley ratio: 6m lifting height requires approximately 22–25m (including 3–5 wraps of drum reserve and rope-end fixing allowance), 12m requires 35–40m, and 18m requires approximately 55m.
Wire rope replacement is determined per GB/T 5972-2016: replacement is mandatory when broken wires within one lay length reach 10% of the total wire count (M4), when rope diameter wear or corrosion exceeds 7% of the original diameter, or immediately upon kinking, crushing, flattening, or arc damage. A visual inspection of the wire rope is required before each shift, with a comprehensive inspection performed monthly.
5t Electric Hoist I-Beam Rail Selection
I-Beam rail options for 5t electric hoists: CD1/MD1 models suit I25a–I63c (hot-rolled I-Beam per GB/T 706), with flange widths of 116–134mm; HC models (square box hoist) suit I28a–I45c, with flange widths of 122–150mm. Material is Q235B (≈S235JR). Rail selection guidelines: spans ≤9m use I25a (lower flange 116mm), 9–12m use I28a (flange 122mm), and spans above 12m use I32a–I45c.
Rail installation accuracy requirements: overall levelness deviation ≤L/1000 with a maximum of 10mm, rail joint misalignment ≤1mm, and joint gaps of 2–4mm (adjusted per working temperature). Polyurethane or Spring buffers must be installed at rail ends. For further installation details, refer to the rail installation section of the Complete Electric Hoist Selection and Installation Guide.
5t Electric Hoist Motor and Power Supply Parameters
The CD1 5t electric hoist has a 7.5kw Hoisting Motor, the MD1 two-speed version uses 7.5/0.8kw (10:1 speed ratio), and the HC model (square box hoist) uses a 7.5kw variable-frequency motor. Travel motors are 0.8kw × 2 units (one for the trolley and one for the Crane Bridge). Power supply standard: three-phase 380V/50Hz, with voltage deviation ≤±10% (lifting speed drops noticeably below 340V). The Conical-Rotor Brake Motor applies automatic Braking on power loss (spring-applied, electromagnetic release), with Class F insulation rated for a maximum working temperature of 155°C and Protection Rating (IP) IP44 (splash-proof).
Electrical wiring requirements: verify correct phase sequence on the main circuit (reversed phases cause the hoist to lower when lifting is commanded — swap any two phase wires to correct). The control circuit operates at 36V safety voltage. Overall Insulation Resistance ≥1MΩ (measured with a 500V Megohmmeter (Insulation Tester)), and Grounding Resistance ≤4Ω. The grounding wire must be ≥2.5mm² yellow/green twin-color cable.
5t Electric Hoist Price Guide
5t electric hoist pricing varies significantly based on model, lifting height, configuration, and brand. Reference price ranges: CD1 5t-6m approximately $560–$810, 5t-12m approximately $740–$1,070, 5t-18m approximately $920–$1,300; MD1 5t-6m approximately $770–$1,110 (20%–30% more than CD1); HC (square box hoist) 5t approximately $890–$1,480. A complete package (including trolley, electrical control box, and Remote Control) costs approximately 30% more than the hoist unit alone.
Price variation factors: brand premium (imported brands like DEMAG and Konecranes run 2–3× domestic pricing), Explosion-proof models cost 50%–100% more than standard units, and Low-Headroom versions run 15%–25% above conventional models. For reference standards, see the Crane Standards FAQ. We recommend confirming a Warranty Period of ≥12 months and requesting the Type Test Certificate at the time of purchase.
Frequently Asked Questions
Q: What size wire rope does a 5t electric hoist use?
A: The 5t electric hoist uses 13mm wire rope for both CD1 and MD1 models, with a 6×37+FC construction and 1670MPa Tensile Strength. A 6m lifting height requires approximately 22–25m of rope, and 12m requires 35–40m. Per GB/T 5972-2016, the rope must be replaced when broken wires within one lay length reach 10% of the total count or when diameter wear exceeds 7%. All Kelude wire ropes come with a Factory Certificate and traceable batch records.
Q: What size I-Beam is needed for a 5t electric hoist?
A: CD1/MD1 5t electric hoists use I25a–I63c I-Beam (flange 116–134mm), while HC square box hoists use I28a–I45c (flange 122–150mm). Spans ≤9m use I25a, 9–12m use I28a, and spans above 12m require I32a or larger. Material is Q235B with rail levelness ≤L/1000. Before installation, verify the lower flange Flatness and Welding quality of the I-Beam, with joint misalignment ≤1mm.
Q: What's the difference between CD1 and MD1 5t electric hoists?
A: The CD1 is Single-Speed (8m/min) with a simple design and economical pricing, ideal for general Factory building Hoisting. The MD1 is Two-Speed (8/0.8m/min) with a 10:1 fast/slow ratio, suited for precision Assembly and mold handling. The HC (square box hoist) offers Work Duty / Classification M5–M7 with a compact design and low Wheel load, making it suitable for frequent operation and export projects. Pricing: MD1 runs 20%–30% higher than CD1, and HC runs 30%–50% higher.
Q: Is a 5t electric hoist classified as special equipment? Does it require inspection?
A: A 5t electric hoist purchased as a standalone unit is not classified as special equipment. However, when installed on a complete crane with Lifting Capacity ≥0.5t, the complete crane must comply with TSG (Special Equipment Safety Technical Regulation) Q7016-2016: supervisory Inspection for new installations, periodic inspection every 2 years for units in service, and annual checks. Kelude Heavy Industry supplies full Factory Certificates and Type Test Certificates with every 5t electric hoist, and assists customers with equipment registration and filing procedures.
