Specialized multimodal heavy lift haulage, riverine barging, hydraulic skidding, 5,000 LPH (5000 lph) transformer oil purification, and plinth placement across Bangladesh. Trusted by SIEMENS, GE, LASTRA, IRCON, and national utilities since 2000.
VisionTech and Swadesh Transport have executed complex multimodal transportation, customs clearance, offloading, and erection logistics for leading multinational engineering conglomerates with 100% satisfaction and zero cargo loss.
Low bed trailer (Low-bed)s, hydraulic multi-axle modular transporters, and heavy prime movers engineered for massive 100-300 ton transformers, turbine rotors, gas exchangers, and boilers over challenging terrain.
Safe indigenous dragging and skidding methods using heavy winches, greased steel plates, and 400mm hardwood sleepers to position massive transformers onto civil plinths with zero foundation shock.
High-vacuum degasification and oil dehydration equipment for transformers dispatched gas-filled or oil-filled. Complete with mobile testing equipment to certify BDV, moisture, and insulation resistance on site.
Statutory inventory of heavy lifting, dragging, oil filtration, and safety equipment deployed for turnkey projects.
