Product Description Product Description40t Movable Double Girder Travelling Gantry Crane for South AfricaGantry crane is a large-scale lifting equipment with a gantry-shaped frame, which operates on ground tracks or is fixed in a specific area, and uses lifting mechanisms, traveling mechanisms, etc., to realize the vertical lifting and horizontal transportation of heavy objects, and is widely used in factories, ports, storage yards and other places.As a heavy-duty main model of gantry cranes, the double-girder gantry crane is characterized by its gantry main girder adopting a double-track structure composed of two parallel load-bearing steel beams.It achieves wide operational coverage via independently operating lifting trolleys, leverages stronger rigidity and load-bearing capacity to efficiently handle precise hoisting of heavy loads, long-distance transport and complex-condition hoisting, and is widely used in heavy-duty scenarios like large ports, machinery factories and metallurgical workshops for its high stability and accuracy.

Operating MechanismWheels:Directly contact the rails or ground to support the weight of the gantry crane and drive the equipment to move.End Beams:Connect the bottoms of the two side legs, distributing the weight of the legs and main beam (including cargo loads) to the wheels and rails through the end beams.Rails (or Ground Foundation):Provide a running path for the wheels and bear the weight of the gantry crane and cargo loads.Safety DevicesContactor: Controls crane circuit on/off with under-voltage/voltage-loss protection.Overload protector: Monitors lifting weight, cuts power on overload.Cross limit switch: Restricts lifting height/travel to avoid overhoisting.Rubber buffer: Absorbs impact to prevent collisions.Circuit breaker: Trips automatically for overload, short-circuit, or under-voltage to prevent electrical accidents.Seamless slide wire: Enclosed design ensures stable power, prevents shock/foreign matter interference.(1)Purchase RecommendationChoosing the right crane is crucial to improving operational efficiency and safety.
