VT 3-ton Chain Hoist

China supplier Baiyi manufacture’s VT 3-ton chain hoist is a high-efficiency, lightweight lifting device with a rated load of 3 tons. Its core components are made of high-strength alloy steel,Make it extremely sturdy and durable.The core working principle is to repeatedly pull the bracelet to drive the lifting sprocket,Furthermore, it drives the load chain to increase and decrease the load. Due to its compact size, convenience, and entirely manual operation, it is particularly suitable for lifting operations without power supply, requiring precise positioning, or operating in confined spaces.

Product Description

The VT 3-ton chain hoist is operated manually,Pull the chain to drive the internal gear set,Realize chain transmission for lifting, lowering, towing, or fixing heavy objects.The name 3 tons refers to the maximum safe working load of the crane being 3000 kilograms.This type of crane is lightweight, portable, and does not require a power source,Suitable for both industrial and household use.

Data:

Parameter Item	Typical Specification /Description
Rated Lifting Capacity	3 tons(3000 kg)
Standard Lifting Height	3 meters(common specification,customizable according to needs)
Test Load	Usually 1.5 times the rated load (4.5 tons)
Hand Pull Force	≤350 N(approx.35.7 kgf),specificallydepending on transmission efficiency
Lifting Chain	Material:High -strength alloy steel(e.g.,G80 grade)Number of strands:Usually single -strand or double- strand Specification:Such as Φ7mm or Φ8mm
Hand Chain	Material:Alloy steel,with anti-rust surface treatment Specification:Usually φ5mm or Φ6mm
Main Material	Shel:High -quality alloy steel Gear:High -quality alloy steel,heat -treated
Net Weight	Approximately 15-25kg (specifically depends on the model and lifting height)

Basic Operating Steps:

1.Inspection: Check the hoist's overall structure for integrity and deformation. Check whether the chain and hook are rusted and deformed,And verify the reliability of the brake.Ensure that the load weight is less than or equal to 3 tons.

2.Suspension:Hang the hook safely on a sturdy and stable support point,Ensure that the support can withstand the total load.Use appropriate rigging to securely connect the lower hook to the lifting point of the load.

3. Lifting and Lowering: Stand on one side of the hand chain and pull it evenly and smoothly; the load will rise accordingly. Do not pull the chain at an angle.

Alternatively, gently pull the other side of the hand chain while simultaneously pressing the release lever or unlocking the mechanism to lower the load slowly and evenly.

4. Positioning and Securing: Once the VT 3-ton chain hoist load reaches the desired position, stop pulling. The ratchet self-locking device will automatically lock to prevent the load from sliding down.

5. Unloading and Storage: After operation, unload the load, clean the hoist, apply rust-preventive oil, and store in a well-ventilated, dry place.

VT 3T chain hoist comparison table with electric hoists：

Comparison Item	VT 3 - ton Hand Chain Hoist	3 - ton Electric Hoist
Power Source	Manual labor (via hand chain)	Electricity (driven by electric motor)
Operating Speed	Slow, dependent on the frequency and physical strength of the operator, typically 0.5 - 2 m/min	Fast, constant speed, typically 4 - 10 m/min or higher
Work Efficiency	Low, high labor intensity, not suitable for high - frequency and long - term operations	High, suitable for frequent, continuous and long - distance lifting operations
Working Height	Limited by manual labor, generally not exceeding 12 meters	Almost unlimited, depends on the length of the chain/wire rope
Precise Control	Excellent, can achieve micro - movement, accurate positioning	Average, requires inching control, accuracy is slightly poor when inertia is large
Dependence Conditions	No power supply required, strong environmental adaptability	Stable power supply (three - phase/single - phase) must be provided
Installation and Movement	Extremely simple, can be hung at a fixed point at any time, excellent portability	Requires fixed tracks or I - beams, complex installation, inconvenient to move
Maintenance Cost	Low, simple structure, convenient maintenance	Relatively high, involves electrical and mechanical systems
