But it is forbided using in inflammable, explosive or erosion environment.

FEATURES

In General

crane mechanism

Compact instructure, low building clearance;

Maximize lifting height to make full use of workshop.

Light body, and small wheel loading;

Variable frequency speed regulation, stable travelling.

Mechanism Parts

Double main girder, welding box beam, camber accord with National Standard.

It is made of carbon steel with high quality of Q235B or Q345B(as Fe37 or Fe52)

The main girder is connected by strength bolt, it can be made as centre-rail or inclined to one side;

Metal structure use steel pretreatment process;

Weld joint between girder cover and web is tested by X ray or ultrasonic examination;

Crane wheel, trolley wheel and brake wheel are treated by untermediate frequency, power frequency;

Leeb hardness tester control heat treatment hardness.

Trolley

Compact structure, small size and light;

Rail is P type or square steel rail;

Consisted with motor, reducer, trolley shelf and hoist.

Trolley travelling is trinity structure;

Lifitng mechanism is similar with hoist's

Crane Travelling

Ground control use soft starting motor with small current, no axial channeling move

Seldom fault, can frequency starting, save energy;

Cabin control use ZDR series cone-shape rotor, three-phase motor or electromagnetic braking mortor;

High mechanical strength, compact structure, braking torque can be adjusted

Starting stablely, safe braking;

Convenient to control, use and maintance;

Use QS trinity drive and doubel-girder hoist special wheel

Simple device and compact structure.

Electrical Part
