Structure of single beam crane

The main beams of single-beam crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. The hoisting trolley is often assembled by chain hoists, electric hoists, or hoists as parts of the lifting mechanism.

　　The electric single-beam crane is a lifting equipment that walks above the workshop, commonly known as a single-beam crane, with a commonly used lifting tonnage of 1-20 tons, a maximum height of 32 tons, and a maximum span of 28.5 meters. Electric single-beam cranes are mainly composed of three operating mechanisms: hoisting operating mechanism, cart operating mechanism, and trolley operating mechanism. The hoisting mechanism is mainly composed of electric hoist, steel wire rope, pulley, hook or spreader. The operating mechanism of the cart is composed of a motor, a reducer, and wheels. The trolley running mechanism is composed of a running trolley, a reducer, etc. The lifting motor adopts a cone-shaped brake motor with a larger starting torque to adapt to frequent direct starting during intermittent operation of the product. The maximum torque is 2.4 to 3 times the rated torque.

The metal structure of the electric single-beam bridge crane is mainly composed of two parts: the main beam and the end beam. The main beam structure is mostly a combined cross section of I-beam and steel plate. It is composed of cover plates, webs and I-beam. Stiffener plate. Its safety and reliability directly affect the operating quality and working ability of the crane.

　　The electronic control system is mainly composed of the control box and the operation button box of the single beam crane, with protection or warning functions such as loss of pressure, interlocking, overload, and overload alarm.
