ABOUT US

The most demanding lifting operations and adverse environmental conditions combined with durability, safety and ease of maintenance: For loads to be lifted, weighing between 500 and 150,000 kilograms!


For over 80 years, more than 500,000 lifting clamps sold by the American lifting clamp pioneer J.C. RENFROE have met these requirements worldwide. It is therefore not surprising that Renfroe lifting clamps are among the most reliable and market leading clamps worldwide.


More than convinced of the advantages and customer benefits of RENFROE products, RUD Ketten, as the world‘s prevailing
manufacturer of lifting and lashing technology, founded a sales subsidiary specialising in this product area for the European market. The resulting HanSol GmbH benefits from its parent company‘s huge expertise and experience in the field of lifting technology and load handling equipment and, with its comprehensive sales network, enables it to be even closer to its customers.


The standard product range on offer includes the most common lifting clamps with different lifting capacities for vertical and horizontal lifting operations. But the HanSol team of experts is also at your disposal for very special or particularly heavy loads.


In close cooperation with the J.C. RENFROE engineers, we develop solutions for our customers‘ highly individual requirements.


Just give us a call, we look forward to hearing from you:

RENFROE LIFTING CLAMPS

Founded in the USA in the 1930s, Caldwell Inc. acquired JC Renfroe in 2013. Perfectly complementing its product range, a new giant for load handling equipment „Made in USA“ was created.


The innovative strength that has been further boosted as a result has so far resulted in over 50 different types of clamps. Quality and variety. All from a single source.

CLASSIFICATION

When classifying clamps in the USA, a distinction is first made between two categories: „design category“ and „service class“.


These are defined according to the safety standard ASME B30.20-2018 and the design guideline ASME BTH-1, which in turn are the counterpart to DIN EN 13155.

2-FOLD
SAFETY FACTOR (WLL 2:1)

 

  • For predominantly identical loads

  • Number of lifting operations are  approximately known

  • No difficult or extreme ambient conditions

  • For slow lifting operations and minimal shockloads

DESIGN CATEGORY

The DESIGN CATEGORY indicates both the safety factor of the clamp and the respective area of application for which the clamp is designed in
this context.

3-FOLD
SAFETY FACTOR (WLL 3:1)

  • For varying loads

  • Number of lifting operations are not known

  • Unknown or difficult ambient conditions

  • For fast lifting operations and  dynamic WLL

6-FOLD
SAFETY FACTOR (WLL 6:1)

  • For varying and very heavy loads

  • For forging and forming work

  • Unknown and very difficult ambient conditions

  • For fast lifting operations, many shock and dynamic WLL

 
Renfroe HanSol_Broschuere_Klemmen_EN_eBook-5A copy.jpg

The clamp classification always consists of a letter (A, B or C) and a number between 0 and 4.


Even if US standards are not applied everywhere, leading global manufacturers use this classification for quick and easy information on the area of application, safety factor and guaranteed load cycles.

The SERVICE CLASS indicates how
many load cycles the manufacturer
must guarantee for the corresponding
clamp type when used correctly.

SERVICE CLASS
