Problems solved by technology

However, the existing electric hoist bridge crane has a large upper part, and the trolley running device is generally not provided with a lubrication device, resulting in large frictional resistance, high noise, and high power consumption during driving. There are usually only two operating methods on one piece of equipment. Too close to the operator has a certain safety hazard. When the operator operates in the control room, the seat cannot be adjusted, which will adversely affect the observation when lifting things of different sizes during operation.

Abstract

The invention discloses an overhead travelling crane with an electric hoist, relating to the technical field of lifting equipment. The overhead travelling crane comprises four main parts including a crane span structure, a bogie operating device, a cart operating device and electric control, wherein the crane span structure comprises a main beam, an end beam, a walking board and a handrail. The overhead travelling crane is characterized in that the bogie operating device comprises a bogie lubrication mechanism; the cart operating device comprises a cart lubrication mechanism; the electric control comprises three control modes, which are control from a control cab, control from floor and wireless control, respectively; and an adjustable seat is mounted in the control cab. The overhead travelling crane with the electric hoist has the advantages of reasonability in structure, lubrication function, small frictional resistance and noise, convenience for control and safety and reliability.

Description

Technical field: [0001] The invention relates to the technical field of hoisting equipment, in particular to an electric hoist bridge crane. Background technique: [0002] The electric hoist bridge crane (referred to as hoist) series is a bridge crane that uses a solid electric hoist (seat type or hanging type) as the lifting mechanism (main hook and auxiliary hook) and is installed on a trolley. The product is simple in structure, light in weight and cheap in price. It is mainly used for general lifting and loading and unloading operations in machinery manufacturing workshops, warehouses, assembly and maintenance of hydroelectric drills and other places. The industrial environment temperature of this product is -25~40℃. It is not suitable for mediums with explosion hazards and fire hazards and places with a relative temperature greater than 85% and filled with corrosive gases, nor is it suitable for lifting molten metals and toxic, flammable, and explosive items. However,...
