The single beam bridge crane is composed of a main beam, two end beams, a cart operating mechanism, a wire rope electric hoist, and an electrical control system; the bridge host is composed of a main beam and two end beams, and the cart operating mechanism is connected by high-strength bolts ; The trolley operating mechanism consists of two motors, two reducers, and four running wheels (two active and two driven) installed on the two sides of the end beam; the electric wire rope hoist consists of the trolley operating mechanism, hoisting mechanism, and electrical system Composition; the trolley running mechanism consists of a motor, a reducer, a small wheel, and an electric. It is installed under the main beam of the bridge crane to move left and right along the main beam, at a normal speed of 20m/min; the lifting mechanism is composed of a motor, a reducer, a reel and The shell, wire rope, hook, and electrical components are installed under the running trolley for ascending and descending operations. There are two types of single-speed and double-speed;
The electrical control system consists of the mainframe cart control box (DK box), electric hoist control box (CD/MD box), overload limiter, fire limiter, travel switch, remote control, collector, seamless sliding contact line , Drop wheel, towing cable, wire drawing, rope buckle, flange bolts and other accessories;
The wearing parts of single-beam bridge cranes include brake ring, rope guide, buffer, travel switch, hoisting reel, and current collector.
The single-beam bridge crane is used in conjunction with the CD1 single-speed electric hoist and the MD1 two-speed electric hoist. It is a light and small hoisting machinery. It belongs to the intermediate work system, and its lifting capacity is 1t-20t. The standard span is 7.5-31.5m. The working level is single beam A3-A5, and the working environment temperature is -25℃～40℃. It can also be customized according to customer requirements.
