  • C.1 GENERAL REQUIREMENTS FOR ALL ELEVATOR …

    7. When a sump pump is necessary on hydraulic elevator installati ons, it must be designed with a sump pump oil sensing control system to allow water to be pumped out without pumping oil/hydraulic fluid from the elevator hoistway pit. The sump pump control system must include an audible alarm and visual indicators for water and oil.

  • Boom stability control: A new solution to reduce - Eaton

    In operation, as the boom is maneuvering and pumping concrete, the tip can oscillate 4 to 6 feet (1.5 to 2 meters). To manage the oscillation, additional workers are typically required to hold the boom tip hose, and concrete pumping speed may also be decreased. This reduces machine productivity and increases the potential risk to workers.

  • Concrete Pumping - How to Pump Cement - Concrete Network

    Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
