ความแตกต่างระหว่างกว้านไฟฟ้าและรอกไฟฟ้าคืออะไร?

The biggest difference between electric winches and electric hoists is that electric winch are heavy-duty, โหลดมาก, อุปกรณ์ยกระยะไกล, while electric hoists are light-duty lifting equipment. This article comprehensively analyzes the differences between the two from various aspects such as functional differences, structural design, application scenarios, and technical parameters.

Definition and core functions

Comparative item	Electric winch	รอกไฟฟ้า
Core functions	Vertical lifting or inclined towing (long distance, large load)	Vertical lifting (short distance, precise lifting)
Main action	The drum retracts and unwinds the wire rope to lift heavy objects or pull horizontally	Motor-driven wire rope lifts and lowers heavy objects vertically
Typical scenario	Construction site hoisting, ship anchoring, bridge construction	Factory workshop handling, warehouse stacking, equipment maintenance

Structure and design differences

Comparative item	Electric winch	รอกไฟฟ้า
ส่วนประกอบหลัก	Large drum, clutch, long wire rope (100 meters level)	Compact drum, hook, limiter, dual braking system
วิธีการติดตั้ง	Fixed on the ground or large bracket, requires independent anchoring	Suspended on I-beam track or fixed beam
Wire rope length	Usually longer (50 meters to more than 300 เมตร)	Shorter (generally ≤30 meters, suitable for vertical lifting height)
Power characteristics	High-power motor, emphasizing continuous traction	Small and medium power motors, emphasizing start and stop accuracy and stability

Comparison of application scenarios

Typical uses of electric winches

• Electric winch for construction engineering: tower crane-assisted hoisting, long-distance lifting of prefabricated concrete parts;
• Electric winch for ship port: large cargo towing, anchor chain retracting and releasing;
• Electric winch for mine rescue: underground equipment traction, personnel lifting;
• Electric winch for special operations: bridge cable stay installation, wind turbine component hoisting.

Typical uses of electric hoists

• รอกไฟฟ้า for industrial manufacturing: production line material lifting, mold assembly;
• Electric hoist for warehousing and logistics: high-level shelf cargo access, container loading and unloading;
• Electric hoist for building construction: installation of light steel structures, vertical transportation of tools and materials;
• Electric hoist for maintenance scenarios: disassembly of machine tool components, lifting of automobile maintenance engines.

Differences in technical parameters between electric winch and electric hoist

พารามิเตอร์	Electric winch	รอกไฟฟ้า
โหลดอันดับ	1 ton~100 tons (mainly traction/lifting force)	0.1 ton ~ 50 ตัน (mainly vertical lifting force)
ความเร็วในการทำงาน	Low speed type: 3-8 เมตร/นาที (large load stability is preferred)	Medium speed type: 5-12 เมตร/นาที (balance between efficiency and accuracy)
วิธีการควบคุม	Mainly controlled by handle, some support remote control	Handle, รอกไฟฟ้าพร้อมรีโมทคอนโทรล, automation integration (frequency conversion speed regulation)
Safety device	การป้องกันการโอเวอร์โหลด, emergency braking, clutch decoupling	ระบบเบรกคู่, limit switch, anti-overroll device

How to choose electric winches and electric hoists?

Electric winch: long-distance lifting/traction, large-load operations (such as bridge construction, mine rescue). Pay attention to the wire rope capacity, continuous working ability, and outdoor protection level (such as IP65).

รอกไฟฟ้า: requires frequent vertical lifting and precise positioning (such as workshop assembly lines, warehouse stacking). Pay attention to the lifting height, speed regulation performance, and track adaptability (such as I-beam model).
