Hand Chain Block EN 13157

The EN 13157 standard refers to safety requirements for manually operated hoists, including hand chain blocks, used for lifting and lowering loads.

Hand chain blocks are designed for lifting and lowering loads manually using a chain mechanism.

Commonly used in construction, warehouses, workshops, and maintenance operations.

Design and Construction: Hoists must be durable, safe, and resistant to damage from normal usage.
Load Capacity: Clearly marked with the rated load (e.g., 1 ton, 2 ton).
Safety Mechanisms: Includes braking systems to prevent unintentional lowering or free fall of loads.
Chain Quality: Load chains must meet specific material and strength requirements.
Testing: All devices must undergo load testing before being certified.
Markings: Essential information, including manufacturer's details, rated capacity, and compliance with EN 13157, must be visibly marked on the equipment.
Safety Considerations:
Regular inspection and maintenance are essential to ensure the equipment remains compliant.
Operators should be trained in safe hoist use.
Avoid exceeding the hoist's rated capacity.

Lever Hoist EN 13157

The EN 13157 standard specifies safety requirements for manually operated hoisting devices like lever hoists. It ensures these devices are safe and reliable when used for lifting or pulling loads.

Scope

Covers manually operated hoisting devices designed for lifting and lowering loads. Applicable to lever hoists used in various industries, including construction, manufacturing, and maintenance.

Safety Requirements

Load Capacity: Must clearly state the maximum load capacity and have safety factors in design to prevent failure.

Materials: Requires durable, high-quality materials resistant to wear, corrosion, and deformation.

Mechanism: Includes provisions for safe load handling, such as secure load brakes to prevent unintended load descent.

Chain: Specifies the use of load chains that comply with relevant strength and durability standards.

Design and Ergonomics

Devices should be easy to operate with minimal physical effort.

Handle designs should reduce operator fatigue and provide a firm grip.

Marking and Documentation

Must include clear markings with:

Manufacturer’s name or logo.

Load capacity.

Unique serial number for traceability.

H-LIFT G80 G100 FORGED LIFTING HOOKS AND LINK EN 1677

Grade 8 & Grade 10 Forged Lifting Hooks and Links EN 1677

EN 1677 is a European standard that specifies requirements for forged steel lifting components used in chain slings and other lifting assemblies. These components are designed for safe handling of heavy loads and are used in industries such as construction, manufacturing, and offshore operations.

Material:

Components are made of alloy steel, which is quenched and tempered for high strength, toughness, and durability. Forged steel is preferred for its structural integrity and resistance to deformation under stress.

Components Covered:
EN 1677 includes specifications for various forged steel components, such as:

Hooks (e.g., eye hooks, clevis hooks, swivel hooks).

Links (e.g., master links, connecting links).

Shackles.

Coupling Devices (e.g., clevis pins, locking mechanisms).

Grades:

Components are commonly produced in Grade 8 (G80) and Grade 10 (G100)

The grade determines the Working Load Limit (WLL) and safety factor.

Safety Factor:

A safety factor of 4:1 is standard, meaning the component must withstand four times its rated load before failure.

Design Requirements:

Components must have smooth surfaces to reduce stress concentrations and prevent fatigue cracks. Dimensions must allow compatibility with chains, ropes, and other lifting equipment.
