The Application
Efficient Tank Truck Cleaning with Precisely Controllable Hoists
Cleaning tank trucks that transport chemicals or food requires precisely controllable spray nozzles, which can be operated using J.D. Neuhaus hoists. The sensitive maneuverability ensures even distribution of the cleaning solution in hard-to-reach areas of the tank. This removes residues, enhances transport safety, and minimizes environmental and health risks. In addition, the flexible control of the spray nozzles allows the cleaning process to be adjusted according to the type of cargo and specific requirements.
High humidity and the use of strong cleaning agents place special demands on the hoists. Consequently, J.D. Neuhaus hoists play a crucial role in the efficiency and effectiveness of tank truck cleaning.

The solution
Customized Hoist Solution for Demanding Cleaning Processes
For this specific application, special load sleeves, a stainless steel chain, and a cable control were manufactured to enable precise positioning of the spray nozzles using JDN hoists. Additionally, ATEX certification is essential due to the explosion risk posed by chemical residues. Given the consistently high humidity and the use of strong cleaning agents, the durability of the hoists is an absolute necessity, as is ease of maintenance to keep downtime to a minimum.
