Product Description

DZX Series Waterproof Limit Switch Tower Crane Construction Machinery Part

 

Product Parameters

DXZ type Multi-function Stroke Limiter is widely applied to control andlimit trilinear coordinates of space of the lifting, transmission in building, port,mining and other industries, DXZ type Multi-functions Stroke Limiter has manycharacteristics, like small volume, many functions, high accuracy,adjustable limit,better compatibility,convenient to install,maintain and adjust.

DXZ Adjustable High Limit Switch is also called Dxz multi-functional travel limiter, Dxz crane lifting limiter, Dxz multi-functional limiter, Dxz limiter, Dxz limiter, dxz multi-functional limit switch. Dxz type multi-functional travel limiter is an essential safety protection device for crane

DXZ Adjustable High Limit Switch, limit device is suitable for AC 50 Hz, voltage to 380 V, DC voltage to 220 V control circuit, as the control of the movement of the travel mechanism or change its direction of movement or speed.

Functions of different models

A user should propose the specifications and quantity of the product required on thebasis of its needs by referring to the following examples:

 

Example 1:

1. DXZ-4/7, which means that the DXZ Limiter has 4 control loops without any

sensors, and its transmission ratio i is 1: 274.

2. DXZ-4/7W, which means that the DXZ Limiter has 4 control loops with sensors, andits transmission ratio i is 1: 274.

 

Example 2:

DXZ-6/F660, which means that the DXZ Limiter has non-standard specifications, has6 control loops without any sensors, and its transmission ratio i is 1: 660.

Installation Instructions

Our Advantages

 

 

Application:

♣ Two way deceleration (or alarm) and limit of crane.

♣ Over lift and over low (or over high) limit and protection.

♣ Amplitude forward (or backward) terminal deceleration and terminal protection.

♣ Rotary forward and reverse limit protection.

♣ The limiter with sensor outputs electric signal to ZXY display instrument.

♣ It can simulate and display the instantaneous space position of the travel.

♣ It is suitable for the control and lifting limit of double beam crane, gantry crane and winch.

 

Features:

♣ Small size.

♣ Many functions.

♣ High precision.

♣ Adjustable limit.

♣ Strong versatility.

♣ Easy to maintain, install and adjust.

 

Structure and working principle:

♣ 1.1 structure of dxz multi-function travel limiter: dxz multi-function travel limiter is composed of high-precision reducer with large transmission ratio, mechanical memory control mechanism and sensor synchronized with its output shaft.

 

♣ 1.2. Working principle of dxz type multi-functional travel limiter: the displacement signal of dxz type multi-functional travel limiter synchronized with the controlled mechanism is connected with the input shaft of the limiter after the speed change of the external change gear, and is converted into the angular displacement signal of the output shaft after the speed change of the crane reducer.
