SafeLift Crane Aid has commissioned the first rebuilt set of 35t Demag hoists, specifically two 15t P Series units, in Northern Manitoba, Canada.
The company used Unique Group’s WaterWeights system for proof-load testing, enabling performance validation without the logistical challenges of solid test weights.
The hoists were rebuilt and reinstalled, then subjected to controlled load tests to confirm safe operation and compliance with industry standards.
The use of WaterWeights, sourced from SafeLift’s rental systems in Saskatoon, enabled rapid deployment for the verification process, which is required for the commissioning, inspection, and certification of cranes and hoists.
WaterWeights provided SafeLift with an alternative method for commissioning and post-rebuild validation, reducing logistical complexity and supporting adherence to regulatory requirements.
SafeLift Crane Aid operations manager Bradley Sliedrecht said: “When rebuilding high-capacity hoists like these Demag P Series units, proper post-installation load testing is not optional—it is essential to verify brake performance, overload protection, structural integrity, and safe return to service.”
Unique Group said: “Great to see our Water Weights in action. Well done to the team and proud to support SafeLift Crane Aid on this project.”
SafeLift Crane Aid operates as a division of Venter Cranes, delivering inspection, maintenance, repair, and modernisation services for overhead cranes and hoists throughout Canada.
The company serves clients across mining, manufacturing, processing, and infrastructure.
In February this year, SafeLift Crane Aid began designing a double-girder crane intended for deployment at a mining site in Canada.
The crane will be manufactured using galvanised materials to meet the corrosion-resistance and durability requirements of mining operations.
