Wire Rope Winch Iran

wire rope winch

A tirfor is a versatile manual pulling and lifting tool. Its nominal pulling capacity ranges from 0.8 to 9 tons across different models. Tension is applied via a dual-pawl lever-operated mechanism. It uses a galvanized steel cable with 6x36 construction and 1770 N/mm² tensile strength. The internal locking mechanism is made from hardened steel with automatic braking. This system allows one-way pulling and load locking in any position. The standard cable length is 1.5 meters, extendable up to 20 meters. The unit weight for a 1.5-ton model is approximately 11 kg.

The tirfor is designed for horizontal, vertical, and angled pulling in tough conditions. The cable has a minimum safety factor of 5:1, and the overall device factor is 4:1. It operates reliably in temperatures from -40°C to +150°C. The body is high-strength cast steel with an electrostatic anti-corrosion coating. Its handles are steel with non-slip polymer coating for enhanced safety. Periodic inspection of the cable, jaws, and lock mechanism every 100 operating hours is essential. Monthly lubrication of moving parts with heavy-duty grease is recommended in dusty environments.

A chain hoist utilizes a gear mechanism and an alloy steel chain, Grade 8. The chain has a minimum tensile strength of 800 N/mm². Standard lifting capacity ranges from 250 kg to 10 tonnes. The gear reduction ratio is typically designed between 1:15 and 1:30. This ratio multiplies the manual input force 15 to 30 times. The housing is made from cast or forged steel with a yield strength of 350 MPa. The hook is manufactured from alloy steel with precise load rating. Each hook undergoes magnetic particle non-destructive testing. This process detects any surface-level flaws.

An automatic load brake with an integrated pressure disc design is used. This brake engages automatically when input force stops. Ideal load positioning accuracy is within ±3 mm. Unit weight for a 1-tonne model is approximately 15 to 20 kg. Periodic lubrication with Lithium-based grease EP-2 is essential. Safety standards like ISO 9001 and DIN 15020 govern its production. An epoxy coating enhances scratch and corrosion resistance. This device is ideal for precise and controlled lifting operations.

The Tiffor is a mechanical tool used for lifting and moving heavy loads in industries, workshops, and construction sites. The Tiffor typically has a load capacity ranging from 0.5 to 10 tons, and it is designed to lift loads to a specified height. The body is made of wear- and impact-resistant alloy steel with heat treatment, and the surface is coated with galvanized or epoxy paint to ensure long-term resistance to corrosion and wear.

Structurally, the Tiffor consists of a steel body, gears, tensioning rod, and attachment hook used to connect to a wire rope or chain. The gear mechanism design ensures that manual effort is effectively converted into lifting power, allowing for smooth load movement with minimal effort. This tool is optimized for heavy industries, workshops, repair shops, and construction, manufactured according to DIN 15307 and ISO 9001 standards to ensure safety and long-term performance.

Electric winch is used in both chain type and towing wire type. Towing winches are often used as construction hoists and to pull loads on surfaces, while chain winches are often used in marine and shipping industries and in connecting ships anchor chains.
Electric winch in low tonnage up to 2 tons is produced in single phase and works with domestic and municipal electricity at 220 volts. The construction of the electric winch is very simple and uses a braked electric motor connected to a gearbox and finally a drum. The use of a braked electric motor in the connection of the electric winch is to lock the system at the moment of power failure and keep the load at a certain height.
