Overview

The current Kromer balancer generation (types 8228 to 8261) neutralises the weight of tools and loads so the operator can guide them with almost no effort. Light and medium types use impact-resistant plastic housings, while the 8241 to 8261 heavy-duty types use cast aluminium housings and drums. Most sizes are offered with or without a lock, and the 8230 and 8235 families also come in rust-free, ATEX and ESD editions.

Infinitely variable load setting via endless (worm) screw
VarioLink rotating and swivelling safety hook and SpringProtector on the 8230/8231 family
Cable wedge for adjusting the working cable length; easy cable replacement
Variants without lock or with ratchet / manual lock to park the load at height
Spring fracture safeguard and safety chain for overhead use
Rust-free edition with stainless cable, NSF H1 lubricant and AquaGuard drain
ATEX edition (II 2G / II 2D) and ESD edition to DIN EN 61340-5-1
Dual-cable 8248 acts as fall protection if one cable breaks
