VG-B Spark Resistant Lever Hoist
Product Overview
The VG-B Spark Resistant Lever Hoist is developed from JENTAN's VG heavy-duty lever hoist platform for lifting, pulling and load positioning in hazardous or spark-sensitive working environments.
Compared with a conventional industrial lever hoist, the VG-B uses specially treated components to reduce the risk of mechanical sparks while retaining the compact structure, efficient gearing and controlled free-chain operation of the VG series.
It is designed for industrial maintenance, chemical processing, oil and gas facilities, storage areas and other applications where additional spark resistance is required.
The VG-B provides an alternative solution for customers who require a robust explosion resistant lever hoist based on a modern industrial lever hoist platform.
Product Features
Spark-Resistant Configuration
Selected external and contact components receive spark-resistant treatment for applications where mechanical spark generation needs to be minimised.
VG Heavy-Duty Platform
The VG-B is based on the proven VG lever hoist structure, combining a compact steel body with reinforced internal components for demanding industrial use.
Clutch Hand Wheel Design
The clutch hand wheel allows convenient free-chain adjustment when the hoist is unloaded, helping operators position the load chain quickly before lifting or pulling.
Operation Without Minimum Preload
The mechanism allows the hoist to engage without requiring significant initial load, providing more convenient operation during installation and positioning work.
Caged Roller Bearings
Caged roller bearings help improve mechanical efficiency and provide smooth lever operation under load.
Double Load Chain Guide Rollers
The dual chain guide structure helps maintain stable chain engagement and reduces the risk of chain misalignment during operation.
Precision-Machined Gearing
High-precision internal gears provide efficient force transmission and stable operation for lifting, pulling and tensioning applications.
Forged Alloy Steel Hooks
Upper and lower hooks are manufactured from forged alloy steel and rotate through 360 degrees for flexible load connection.
High-Strength Load Chain
The VG-B can be equipped with high-strength load chain suitable for industrial lifting applications and different market requirements.
Optional Overload Protection
An overload protection system can be supplied where additional load control is required.
Application Scenarios
The VG-B Spark Resistant Lever Hoist is suitable for lifting, pulling and positioning applications in:
• Oil and gas facilities
• Chemical processing plants
• Petrochemical maintenance
• Fuel and material storage areas
• Industrial plants with flammable materials
• Marine and offshore maintenance
• Equipment installation
• Hazardous or spark-sensitive work areas
Because a lever hoist can operate vertically, horizontally or at an angle, the VG-B is particularly suitable for maintenance and installation work where precise load positioning is required.
