Explosion Proof Manual Chain Hoists Product Introduction
Explosion proof manual chain hoists are specially designed for explosive environments (ATEX explosion-proof certification) to ensure safety and reliability in high-risk environments. Aluminum bronze and beryllium bronze are used as blanks, and the shell is made of H62 copper alloy material. Its rotating geaexhibits high wear resistance after high-temperaturere heat treatment. Friction and collisions during operation will not produce mechanical sparks, and gas will not detonate in flammable or explosive areas, effectively preventing fires.
Spark resistant manual chain hoists are manual lifting machinery that is easy to use and easy to carry. It has low tensile strength and a light weight, is easy to carry, has a beautiful appearance, is compact, and is durable. In addition to standalone use, the explosion-proof hand-pulled chain hoist can be used with a hand-pushed monorail to enable left-right walking to lift heavy objects. The installation and disassembly of the explosion-proof chain hoist are very convenient, safe and fast.
Explosion proof manual chain hoists are suitable for petroleum, petrochemical, oil stations, oil depots, gas extraction, chemical industry, military industry, electric power, mining, electronics, railways, etc. In hazardous environments with potential fire and explosion, as well as lethal gases.
Explosion Proof Manual Chain Hoists Features
- Accord with EC machinery directive 2006/42/EC ATEX Directive 2014/34/EU/EN13157.
- Equipment classification Gas ATEX Explosion Protected II 2G EX h IIB T3 Gb (zone 1).
- Equipment classification Dust ATEX Explosion Protected II 2D EX h IIIB T200°C Db (zone 21).
- Unique Hand Wheel Design – This feature enables the hand chain to successfully feed directly into the wheel sprocket from many directions and angles. Thus, the operator can use the hoist while standing to the side of, or even above the load without fear of the hand chain jamming.
- Fully Enclosed Gearing – This protects the gears from contamination and debris.
- Coating Load Chain — Providing a durable, oil-free, spark-resistant coating.
- Fully Machined Lift Wheel – This feature perfectly accepts the chain allowing for a smooth long lasting operation.
- Lifting or Pulling – This hand hoist can be used for lifting or pulling which makes for a more flexible and versatile tool.
- Weatherproof Load-Holding Brake – Chain hoists have a weatherproof brake that holds the load throughout operation. The hoists are also equipped with a unique twin pawl design.
- All Gears and Shafts Run on Roller Bearings – This feature provides smooth, controlled operation and maintenance-free lubrication.
- Explosion-proof copper-coated bottom hook to prevent sparks from the contact point.
Compatible Monorail Trolley Options
Explosion proof manual chain hoists can be used independently or combined with a hand-pushed monorail trolley to enable horizontal movement while lifting heavy loads. The following two trolley configurations are available:
Brass Explosion Proof Manual Trolley
- The chain is made of H62 brass, providing higher strength and preventing sparks caused by friction.
- The housing cover is made of H62 brass with thickened construction, offering excellent impact resistance.
- The cover adopts interlocking and rolled-edge processing, ensuring a compact structure, small installation size, convenient operation, and easy maintenance.
- With a simple structure and easy operation, this lightweight lifting accessory is driven by a hand chain to lift loads. It can be combined with manual chain hoists or electric chain hoists to form a lifting transport trolley.
- It can run smoothly along the lower flange of I-beam tracks, including tracks with a certain curvature radius, and can be installed on straight or curved monorail overhead transport lines, as well as manual single-girder cranes, bridge cranes, and jib cranes.
Stainless Steel Explosion Proof Manual Monorail Trolley
- In addition to all the characteristics of standard manual trolleys, this model offers excellent corrosion and rust resistance.
- The entire product is made of 304 stainless steel, featuring compact dimensions and easy installation.
- The chain and housing cover are made of 304 stainless steel, providing higher strength. Precision welding at the joints ensures reliable performance even under sudden overload conditions.
