    Sammanfattning : The aim of this thesis is to quantify the consequences of a fire in Kalmar Globals Heavy Electric Forklifts and Electric Reachstackers as well as what actions can be taken to reduce the effects of an ongoing fire and what preventing measures can be made by Kalmar Globals customers to create a safe environment and reduce the probability of a fire breaking out. This thesis builds on information gathered during a literature study and a complementary interview study. LÄS MER

    Sammanfattning : This thesis proposes a deep learning anomaly detection pipeline to detect possible anomalies during the operation of a fleet of batteries and presents its development and evaluation. The pipeline employs sensors that connect to each battery in the fleet to remotely collect real-time measurements of their operating characteristics, such as voltage, current, and temperature.

  4. 3. Evaluation of Traction Control Systems for an Electric Forklift Truck

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mattias Karlsson; Sebastian Johansson; [2021]
    Nyckelord :forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Sammanfattning : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

  5. 4. Hållbarhetsutvärdering - LCSA Analys : av trucksystem inom intern materialhantering

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för handel och företagande

    Författare :Erik Dahlberg; Weronica Fohlén; [2018]
    Nyckelord :sustainability evaluation; LCSA; LCA; LCC; SLCA; forklift systems; co2 equivalent; hållbarhetsutvärdering; LCSA; LCA; LCC; SLCA; trucksystem; koldioxidekvivalentutsläpp;

    Sammanfattning : Allt fler organisationer väljer att jobba med hållbar utveckling, på grund av att det kan ses som en konkurrenskraft. Att arbeta med hållbar utveckling kan innefatta att utföra hållbarhetsutvärderingar, vilket kan göras genom metoden LCSA analys. LÄS MER

  7. 5. Modelling of Test Bench for Road Load Simulation

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Dennis Åberg Skender; [2017]
    Nyckelord :modelling; test bench; road load; simulation; test rig;

    Sammanfattning : Warehouse forklifts are often powered by batteries. By using a test bench where the forklift can be driven in a certain driving-cycle, the battery capacity can be tested. To obtain the same speed curve on the test bench as a forklift obtains when driving on a real road, the test bench must be able to simulate road load. LÄS MER
