15 Years Electric Wire Rope Hoists Manufactruer

Introduction

The lifting speed of CD1 wire rope electric hoist is single speed; MD1 wire rope electric hoist has two kinds of lifting speed, the ratio of high and low speed is 1:10, which is especially suitable for the occasions that require fine adjustment work. The electric hoist is divided into fixed type and running type. The fixed electric hoist is divided into four installation modes: upper (A1), lower (A2), left (A3), and right (A4). The lower fixed electric hoist is often used in combination with the LH electric hoist double beam. The running electric hoist can perform linear reciprocating motion in the horizontal direction as well as curved motion on the limited arc track. The running electric hoist can be used with LD electric single beam crane, LX electric suspension crane, MH electric hoist gantry crane, BMH electric hoist semi-gantry crane, cantilever crane, etc. to form a variety of hoist cranes.

The design and manufacture of electric hoists meet the standards of GB3811-2008 "Design Specifications for Cranes" and JB / T9008.1-2004 "Wire Rope Electric Hoists Part 1: Types and Basic Parameters, Technical Conditions". The working environment temperature is -20 ℃ ～ + 40 ℃, the atmospheric pressure is 0.08 ～ 0.11Mpa, the relative humidity is 85% (25 ℃), the rated voltage of the power supply is 380V, and the rated frequency is 50Hz.

When the electric hoist works under rated load, when the lifting weight is ≤ 5 tons, the noise sound pressure level does not exceed 85dB (A), and when the lifting weight is> 5 tons, the noise sound pressure level does not exceed 90dB (A).

Our company has a 22-year history of design and production of electric hoists. We have accumulated rich experience in the design and production of electric hoists, and can design non-standard electric hoists adapted to various working conditions.

CD1, MD1 wire rope electric hoist is mainly composed of: lifting motor, reducer, drum device, hook group, electronic control system, running trolley, safety device and so on.

Features

Overload protection limit switch to protect the hoist from overload operation;
Lift height limit switch to protect the hoist from the hook reach the up/down limit;
Power failure protection to protect the hoist from the low voltage and power failure;
Motor's protection grade is IP44 with F for insulation grade based standard;
For ex type condition, the EX grade of the motor and electricity will be EX dII BT4/CT4;
For metallurgical condition, the insulation of the motor will be H grade, and there is high temperature resistance cable and thermal baffle to protect the crane from the heat.
