10 Ton Single Girder Gantry Crane with Electric Trolley

 MH type single girder gantry crane has box type and truss type, the former have good techniques and easy fabrication, the latter is light in dead weight and strong in wind resistance. For different usage, MH gantry crane also has cantilever and noncantilever gantry crane. If have cantilevers, the crane can load the goods to the crane edge through the supporting legs which is very convenient and high efficiency.

STRUCTURE CLASSIFICATION
(a) Class of utilization – U7 (two million loading cycles) 
(b) State of loading – Q 2 
(c) Group classification – A 7 
(d) Impact factor – 1.3 
(e) Duty factor – 0.95
(f) Nominal load spectrum factor – 0.63 of rated capacity.
(Or as your requirement)
 
MAIN HOIST:: 
The wire ropes reeving configuration, and sheaves of the main hoist system designed to ensure that wire ropes do not dislodge from the sheaves (or jump off sheave groove) under any operating condition. The design shall prevent excessive slackening of the main hoist ropes and also limit the hoisting speed when the ropes are slack. Slack rope condition monitored through the load cells and back-up by limit switches installed at the girder end. Load cells provided for every hoist ropes. 

AC motors used for the main hoist system. The motors coupled to the reducer through gear couplings or flexible coupling. 

Two sets of fail safe disc brakes assemblies be fitted on the drive. The braking torque of each set of brakesat least 150% of rated load torques. Normal container handling operation with loads up to the rated capacity possible with only one set of brakes.
 
Main Parts of MH model gantry Crane:
SPREADER LIST, TRIM AND SKEW ADJUSTING DEVICES: 
The Crane equipped with spreader tilt and skew adjustment devices. The devices of sufficient stroke to tilt the spreader with a rated load to at least ±3 degrees (about a vertical plane). Sufficient clearance maintained between any part of the spreader (with flipper at raised position) and crane structures (e.g walkway leading to operator cabin) especially when trolling and spreader is tilted or skewed to the maximum. Tests for above requirement conducted during acceptance, testing and commissioning of the cranes.
 
OPERATOR’S CABIN
The operator’s cabin firmly secured in a fail safe manner. The roof inclined 
to drain away rain water. Safe passage or walkway provided from the yard side leg to enable the operator to enter the cabin from the rear through a sliding door. Safe and easy 
escape from the cabin at any trolley position made possible for emergency purposes 
without having to move the trolley back to the parking position.
It’s not suitable for lifting blazing & melting metal or toxicant 
as well as explosion-proof or insulating working conditions.
