In case the degraded wire or chain breaks,
the HEIWA Lactor does not fall more than
25 mm (according to our test results).
The HEIWA Lactor uses two rails. This structure makes the Lactor less likely to shake while it is moving up or down, providing the unloader main unit with increased stability. It also provides smooth motion, giving longer service lives to failure-prone components, such as the bearing.
When the scaffold makes it difficult to take out or load
a structural component, you can turn the box up to
120 degrees by pulling the lever (four-step turning).
The aluminum boxes have increased the maximum
allowable load to 160 kg for chain hoisting.
The HEIWA Lactor allows four or five workers to perform construction work that usually required 10 workers! This increases the velocity, leading to increased profitability. The Lactor is for rent, eliminating the great expense required to purchase unloaders.

Mini winch (8 kg)
Hoist mounting bracket (18 kg)
However, an unloader may become dangerous equipment when used wrongly. We require you to attend a lecture class provided by us before you use the Lactor if you will use it for the first time. We would like you to adhere to the correct usage so that you can use the Lactor safely and quickly.
Through the manufacture and sale of temporary equipment for building and civil engineering,
we have been making efforts to meet the diverse needs of our customers.
Now, we live a new era of technology, where the building techniques are becoming more and more advanced and diversified.
In step with these advanced and diversified techniques,
we are also focusing our efforts on developing higher-quality products and making environmentally-friendly products.
We think about people and the environment to make proposals toward the future.
