VT Series Manual Chain Block: The Ultimate Guide to Safe & Efficient Lifting

The Powerhouse of Industrial Lifting: A Deep Dive into the VT Series Manual Chain Block
In the world of heavy industries, precision and safety aren't just requirements—they are the backbone of every successful project. Whether you are operating in a bustling construction site, a high-tech shipyard, or a remote mining facility, your equipment must be as resilient as the structures you build.
Enter the VT Type Manual Chain Block. Known for its rugged durability and ergonomic design, the VT series has become a global benchmark for manual lifting solutions. In this guide, we’ll explore why this specific model from Tieshou Lifting stands out in a crowded market.

What is a VT Type Manual Chain Block?
The VT Type Manual Chain Block is a portable lifting device operated by a hand chain. It is designed to lift, pull, and tension heavy loads with minimal manual effort. Unlike standard hoists, the VT series incorporates advanced gear geometry and high-grade materials to ensure smoother operation and a longer service life.

Key Specifications at a Glance:
Capacity Range: 0.5 Tons to 20 Tons.
Standard Lift: 3 meters (Customizable lengths available).
Material: High-strength alloy steel housing and G80 load chain.

Top 5 Features That Define VT Series Excellence
When selecting a hand chain hoist, it’s the internal engineering that counts. Here is what makes the VT series a leader:
1. Premium G80 Alloy Steel Load Chain
Safety starts with the chain. The VT series utilizes G80 (Grade 80) heat-treated alloy steel chains. This ensures the hoist can withstand extreme stress without deformation, providing a high safety factor for overhead lifting.
2. Double-Pawl Braking System
Redundancy is key to safety. The VT type features a double-pawl braking system that provides instant and secure braking. If one pawl encounters an issue, the second ensures the load remains locked in place, preventing accidental slips.
3. 360° Swivel Hooks with Safety Latches
Maneuverability is crucial in tight spaces. Both the top and bottom hooks are drop-forged and designed to rotate a full 360 degrees. Equipped with heavy-duty safety latches, they ensure the load stays hooked even during complex shifts.
4. Impact-Resistant Gear Cover
Industrial environments are harsh. The VT series is encased in a thick, impact-resistant steel shell that protects the internal gear mechanism from dust, debris, and physical knocks.
5. High-Precision Friction Discs
The braking surface is made from asbestos-free friction discs, ensuring a smooth, wear-resistant grip that meets international environmental and safety standards.

Applications Across Industries
The versatility of the VT manual chain block makes it indispensable across various sectors:
Construction: Lifting steel beams and positioning heavy machinery.
Mining: Installing equipment in confined underground spaces where electricity is unavailable.
Manufacturing: Precise positioning of molds and heavy components on assembly lines.
Marine & Offshore: Withstanding corrosive environments thanks to its specialized coating options.

Maintenance Tips for Longevity
To get the most out of your Tieshou VT Chain Block, follow these simple maintenance steps:
Daily Visual Check: Inspect the chain links for nicks, gouges, or stretching.
Lubrication: Keep the load chain and gear shaft well-lubricated with industrial-grade grease.
Avoid Side Loading: Ensure the lift is always vertical to prevent unnecessary wear on the chain guide.
Annual Load Test: Conduct a professional load test once a year to verify braking efficiency.

VT Series Manual Chain Block FAQ

Q1: What is the difference between a VT type and a standard chain block? 

A1: The VT type typically features a more compact design and upgraded gear materials, offering higher mechanical efficiency and better durability in heavy-duty cycles compared to "economy" models.

Q2: Can I use the VT chain block for horizontal pulling? 

A2: While primarily designed for vertical lifting, it can be used for tensioning. However, for dedicated horizontal pulling, a lever hoist (come-along) is often more ergonomic.

Q3: Is the VT series compliant with international standards? 

A3: Yes, all VT series hoists from Tieshou Lifting are manufactured to meet CE and ISO safety requirements, ensuring they are fit for global industrial use.
