U Type Large Span Dock Yard Material Handling Gantry Crane Installation for Ship Building
U type material handling gantry crane usually have long crane span,heavy loading capacity,large rail distance between beams. This kind of structure is easier to lift big size heavy block material.
More stable, more safe, more efficiency.The crane is combined by the bridge, cart running mechanism, car and electrical equipment. Bridge with box welded structure, cart running mechanism driven respectively. Crane control have the ground operation, remote control and bridge operation. Crane electric power supply have cables and bus bar you can choose any one of when you order it. U type Large Span Gantry Crane have 10-35/10 tons capacity, working environment temperature is 25 ~ 40 ℃.Overload capacity is strong, large working area, suitable for large span, heavy rail freight yard, port loading and unloading operation, open storage, container depot, etc.
Safety Feature with Protection Device for Gantry Crane:
(1) lifting height limit position limiter
For by changing the crane luffing boom Angle, when the top hook device to distance the lower boom 800mm, must immediately stop lifting movement.
In car luffing crane, when the hook assembly top to bottom at 500 mm distance from the car frame.Must immediately stop lifting movement.
(2) the crane moment limiter and the maximum lifting weight limiter
When lifting moment amounted to 90% of its rating, crane moment limiter should be able to send audio or red light, as a sign of alarm.When lifting torque exceeds its rating and rating of 108%, should stop ascending direction and the direction of the outward luffing movement.
Such as sets up the weight indicator, and amplitude numerical display should correctly and clearly marked.Its digital error shall be greater than 5% of the indicated value.
When lifting weight more than the maximum weight, maximum lifting weight limiter should be light or sound alarm, when hoisting by more than 6% of the maximum lifting weight, should stop ascending in the direction of movement, but allow institutions facing down direction.
(3) the amplitude limit device
To boom luffing crane, should furnish minimum amplitude limiter and to prevent boom recovery device.Must be installed to the juki car horns, the car trip switch and terminal buffer device.
(4) walking rail and the limit switch
Rail type crane rail device must be installed.Should be installed at the same time walking limit device.
To boom root hinge point height of more than 50 m crane, must be installed at the top of anemometer.
(6) the lightning protection and the electromagnetic induction device
To boom root hinge point height of more than 50 m crane, lightning protection equipment should be based on actual situation and to prevent electromagnetic induction measures.
(7) tower crane to prevent rotary overload should limit moment coupling
(8) to take off the rope device To prevent the wire rope from the work location
(9) the car broken rope device Prevent the luffing rope broken car free sliding
The broken shaft device.
(10) cars To prevent the car wheel broken shaft after the fall
Each part of the
(11) Brake unit Is also a safety device.
