LDY type metallurgical single beam crane used in the casting industry
Product Introduction
nine hundred
1、 Overview
This manual is applicable to the installation, use, and maintenance of LDY type metallurgical electric single beam crane, for installation, operation, and maintenance personnel to use.
1. Main purpose
The LDY type metallurgical electric single beam crane (hereinafter referred to as the crane) is in accordance with the JB/T1306-2008 standard and complies with the quality inspection office's [375] document

The space transportation tool designed to be used in conjunction with the YHII electric hoist is mainly designed to work intermittently and periodically through a lifting crane

The timely and rapid completion of the displacement of heavy objects required for lifting and transportation in the metallurgical production process by hooks or other lifting devices is crucial for modern industrial enterprises
Important tools and equipment for improving labor productivity in casting sites.
2. Scope of Application
The LDY crane is suitable for working at level A6 and ambient temperature; 60 ℃, relative humidity≤ 85%, altitude below 2000m, no

Working under corrosive medium environmental conditions.
3. Environmental conditions
(1) The power supply of the crane is three-phase AC, with a rated frequency of 50Hz and a rated voltage of 380V (if the power supply voltage and frequency do not comply with this regulation)
At the same time, the power supply voltage and frequency of the place of use should be indicated when ordering. The upper limit of allowable voltage fluctuations on motors and electrical control equipment is rated power

The voltage is+10%, and the lower limit (at peak current) is -15% of the rated voltage. The internal voltage loss of the crane is 5%< Br/>
(2) Crane working environment: temperature≤ 60 ℃, humidity≤ 85%, below an altitude of 2000m, without fire, explosion, or corrosive media.
4. Noise
The crane is measured on the ground in a non enclosed factory building without any other noise interference and with a lifting height of no less than 5m. The lifting capacity Q

&Le; At 5t, the overall noise of the machine shall not exceed 85 dB (A), and the lifting capacity Q≥ At 5t, the overall noise of the machine shall not exceed 90 dB (A)
2、 Structure and performance parameters of cranes
The structure of the crane mainly consists of three parts: bridge, metallurgical electric hoist, and electrical system (see Figure 2 and random diagram)< Br/>
The bridge is used to support and move loads longitudinally, consisting of a metal structure and a running mechanism. The metal structure includes the main beam, end beam, and the connection between the main and end beams

Continue with three parts. The operating mechanism consists of four parts: driving device, transmission device, braking device, and wheel group. Metallurgical electric hoist undertakes lifting and horizontal

Move the load towards. The electrical system consists of a main circuit and a control circuit.
1. Bridge
The main beam is composed of cold-formed U-shaped channel steel and I-shaped steel welded together to form a solid web beam or welded together with steel plates to form a box beam. The end beam is welded into a box using U-shaped channel steel

Shape structure, with bolt and shear flange connection structure or seat structure between the main and end beams, for installation
