Gantry Crane / Portal Cranes
Street Portal cranes are the perfect solution to efficient lifting and handling in many industry applications such as in open stockyards – many such applications are heavy duty and require fast speeds to achieve required cycle times. With the use of software tools we can provide an analysis of the necessary crane speeds, utilisation and load spectrum for the specified stock movements in a given application. By this method we ensure each crane is a bespoke solution to give reliable service through the appropriate duty classification of mechanisms, structures and electrical systems. Street pre-engineered Goliath cranes provide efficient and competitively priced solutions for manufacturing and maintenance applications on indoor and outdoor sites. A cantilevered beam construction is an option whereby the load can be transported outside the rail centres as may be required for roadside loading bays or when loads need to be transferred from one crane to another (see application picture).
