Interconnection members maintain connector alignment during welding, preventing thermal strain misalignment and reducing equipment complexity.
Segmenting the boom allows a guyed inner section to support loads while a tapered outer bending beam reduces overall height and weight.
A crane jib profile shape combines arcuate and straight sections to enable reliable longitudinal welding without edge preparation.
Electric motor drives screw mechanism to insert fixing pins, eliminating hydraulic viscosity issues in low temperatures.
An automated winch lifts the structural frame from a horizontal transport position to a vertical operational stance, eliminating manual securing pins.
A crane control system reduces parameter change speed before reaching safe working load limits.
A combined counterweight hitching device uses a spherical hinge to connect the piston rod and hitching platform.
Multiple counterweight attaching positions on a crane swiveling body allow selective attachment to change moment without increasing total vehicle weight.
Electrodynamically controlled slewing gear brake adapts torque via electric motor operation, preventing auto-rotation under wind loads.
A mobile lift crane adjusts counterweight position along a lattice mast to balance loads without ground support.
Electronic inclination sensors and processing units regulate electro-hydraulic outriggers to stabilize work machines.
Segmented part-jibs with flexural connectors increase the area moment of inertia, eliminating separate anchoring supports and reducing assembly time.
Lowering the mast aligns the lower spreader with the fixed retainer, eliminating manual position adjustment during attachment.
