The KPJ series electric transport cart is a cable drum powered electric flat cart. A cable drum is provided on the electric flat cart. The cable drum is a magnetically coupled cable drum to ensure that the cable is force-free and evenly arranged and released (there is an automatic cable arrangement device for more than 50m). The cable drum supplies 380V power to the metallurgical motor on the flat car, and the motor drags the flat car to run smoothly through the reducer. When the flat car is running, the cable drum automatically rolls up or releases the cable. Affected by the power supply length of the reel, the maximum running distance is generally less than 200m. This series of electric transport cart is suitable for hoisting metallurgy in harsh industrial and mining conditions. The flat car has a simple and reliable structure, economical price, convenient maintenance, and convenient track construction. It is a set of traditional electric rail flat car selection solutions; suitable for large-tonnage over-span solutions. This flat car is suitable for hoisting metallurgy in harsh working conditions. The flat car has a simple and reliable structure, economical price, and convenient track construction and maintenance.

The main structures of the KPJ series electric transport cart include frame, motor, reducer, wheel, cable drum,frame, control box, etc.

The frame structure of the trolley is a frame structure welded by four longitudinal beams, several cross beams and a work table cover. The support method adopts an eight-point load-bearing form. This structure and the bearing seat on the wheelset effectively reduce the height of the table and improve the force of the frame. The work table is equipped with a detachable inspection hole, and four lifting holes or hooks are provided on both sides of the frame for lifting and turning over. The longitudinal beams and cross beams of the frame are combined in the form of I-beams and channel steels of the same number, and the work table panel is made of high-quality carbon steel plates. The frame strength is designed to be 1.25 times the rated load, so as to ensure that the load frame will not deform when subjected to a certain impact.

Motor

The motor is a YZ series lifting metallurgical motor with a rated voltage of 380V, a rated frequency of 50HZ, a power of 3.7~7Kw, an insulation grade of F, and a protection grade of IP44. The power of the motor can be selected according to the rated tonnage of the electric flatbed truck.

Electric flatbed car reducer:

It adopts the heavy-duty standard of the lifting and transportation industry, and is dedicated to the shaft-holding hardened surface flat car. It has a compact structure, high reliability, good versatility, and is easy to install and maintain. The gears are all made by carburizing, quenching, and grinding, and are produced by a professional gear manufacturer.

Electric flatbed car wheels

The wheels are special wheels for cranes. The wheels are made of ZG55, overall quenching, and the hardness of the wheel tread and the inner side of the wheel rim is HB320-380, with a depth of 20mm; the axle is made of 45 steel quenching and tempering heat treatment, the bearing seat is made of ZG45, and the bearing is a radial roller bearing. The axial automatic micro-alignment of the bearing can eliminate and overcome the elastic deformation of the flat car under no-load and full-load conditions and the deviation of the horizontal parallelism of the track, ensuring the balance of the flat car on the track and improving its service life. After the wheel is assembled, it rotates flexibly, and the wheel is a single wheel rim. Considering the wheel pressure of the electric flat car, the wheel adopts a heavy-duty wheel dedicated to the crane, 4 wheels and 2 drives.

Cable reel for electric flatbed truck

This series of electric transport cart is powered by a cable reel. The frame is equipped with a cable reel. The cable reel reels and unwinds the wires when the trolley moves backward and forward.

Onboard control box: (If a remote control is installed, the effective distance is 100 meters)

The onboard control box consists of a control box and a control cable. The control box is equipped with forward, backward and emergency power-off buttons, and the control cable is about 2.5-3 meters long. The onboard control box can be stored in a box on the side of the flatbed truck when not in use, and taken out for operation when in use.

Sound and light alarm: To remind other staff to avoid and ensure safety when the flatbed truck is running. Each flatbed truck is equipped with a new type of sound and light warning integrated alarm at both ends of the front of the truck.

Control box for electric flatbed truck: The control box is installed on the lower side of the electric flatbed truck frame to play a protective role. Electrical components are all selected from products with high technological content and good reliability. The control system is equipped with leakage protection switch, overload protection and emergency power-off control elements, and the control circuit is set to a safe voltage of 36V. The entire set of electrical equipment has power distribution protection, short circuit protection, overcurrent protection, pressure loss protection, zero position protection, emergency power-off protection, safety signs, etc., ensuring that the transmission performance, control performance, and protection performance are safe, accurate and reliable, and can stop safely in an emergency.
