3~5T A3 LZ type single beam grab crane for factory single girder overhead travelling crane
Product description of 3~5 Ton Single Beam Bridge Crane With Electric Hydraulic Double Flap Grab:
LZ grab bridge crane is based on LDA and travels with the grab bucket through a wire rope hoist or a hoist trolley.Cranes generally work indoors, and the working environment temperature is -20℃~50℃.The grab can be customized according to customer needs. The split electro-hydraulic grab can be used in water.
The relative humidity of the air does not exceed 85%. The crane adopts a single main beam structure, and uses an electric hoist as a lifting mechanism, which is suspended on the lower edge of the main beam for lateral movement.
Ground operation adopts squirrel cage motor with self-contained
plane brake. Conical winding brake motor is used when operating in
the cab. The brake is a conical brake. The reducer adopts one-open
and one-close or one-open and two-close involute gear deceleration.
Device.)
LDZ type electric overhead single girder grab crane is a light lifting equipment with the lifting mechanism of electric grab,and it can travel on the rails with suitable structure,the whole crane has strong rigidity.
This type crane sit on the tall concrete pillars or mental supports,its shape looks like a bridge.Single girder overhead crane runs longitudinally along the rails laid on the elevated on the both sides.This is able enough to lift materials under the bridge without being hindered by the ground cargo.Single girder overhead crane is one of the most used and largest number of lifting machinery.
Control method:
LDZ type single girder overhead grab crane mainly has two operation methods:ground control and air cabin control with closed model or open model;cabin can be installed on the right side or left side of crane according to the practical situation.And the direction of entering the gate has two forms:sideways and ends in order to satisfy the users’ choice ,users’ different conditions.
Application:
Single girder overhead crane is a main tool and equipment for mechanization and automation of processing in the modern industrial manufacturing and lifting transportation areas.Single girder overhead grab crane is mainly equipped with light class grab for grabbing and transporting materials,so this type crane mainly used for grabbing places such as lump coal, coke, slag, cement and so on.
Product configuration:
LDZ type single girder grab overhead crane mainly includes four parts:mental structure part(main beam and end beam,sometimes including traveling tracks),trolley and crane traveling mechanism,electrical control part and lifting mechanism.
1. Mental Structure Parts: main beam, end beams, traveling tracks;
(1) The main beam adopts the U-shaped groove formed by the steel plate,and then forms the box-shaped beam with the I-beam.The end beams are also rolled into the U-shaped groove with the steel plate,welded into the box-shaped end beams.The main beam and end beams are connected by bolts.
(2)We can supply traveling tracks and bus bar for clients according to customers’ requirements.There have three methods of tracks’ installation:Welding method; bolt fixing method; hook bolt method.
2.Traveling Mechanism: trolley traveling mechanism and crane traveling mechanism.
The traveling of electric wire rope hoist and crane is controlled separately;and traveling motors adopts soft-start squirrel cage with disc-brake;The traveling speed of them is about 20 or 30m/min.
3.Electrical Parts are equipped by famous international electrical brands,The power supply system of the single-girder bridge crane adopts "multi-level seamless sliding line".
4. Hoisting Mechanism:The hoisting motor adopts a large starting torque conical rotor Squirrel cage motor with disc brake; the hoisting mechanism uses light class grab.
