Problems solved by technology

Although tire-type cranes have the characteristics of flexible maneuverability, large capacity, large operating range, compact structure, safe and reliable operation, convenient operation, beautiful appearance, and good comfort, they cannot meet the requirements for construction sites far away from hardened roads. Especially for the wetland type areas that require low grounding specific pressure, it is difficult for the tire crane to drive. Due to the small area of ​​the outriggers during work, the pressure generated is very high, making it impossible to carry out construction work

Abstract

The invention relates to a novel hydraulic crawler crane, which is the improvement of wheel crane through replacing wheel type chassis by crawler chassis. The invention comprises a crawler chassis (1), a turntable (3) arranged on the crawler chassis (1) through a turning gear (5) and a turning support (2), a lifting mechanism (4), a hydraulic device (9), a power device (10), a balance weight assembly (11) and a driving cab (12) which are arranged on the turntable (3), a telescopic boom (6) hinged with the turntable (3), a sling dog (8) arranged at the other end of the telescopic boom (6), a telescopic oil cylinder arranged inside the telescopic boom (6), a derricking oil cylinder (7) hinged with the turntable (3) and the telescopic boom (6), a hydraulic device (9) and a power device (10) ,etc. The invention is characterized in flexible maneuvering, large working scope, a compact structure, safe and reliable working, convenient operation, aesthetic appearance, ideal comfortableness, being capable of working in wetland type region, low earthing specific pressure and needing no support of outrigger etc.

Description

1. Technical field: [0001] The invention relates to a construction machine, in particular to a novel hydraulic crawler crane. 2. Background technology: [0002] Cranes are essential construction equipment during field construction operations. Although tire-type cranes have the characteristics of flexible maneuverability, large capacity, large operating range, compact structure, safe and reliable operation, convenient operation, beautiful appearance, and good comfort, they cannot meet the requirements for construction sites far away from hardened roads. Especially for wetland type areas that require low grounding specific pressure, it is difficult for rubber-tyred cranes to drive. Due to the small area of ​​the outriggers during work, the pressure generated is very high, making it impossible to carry out construction operations. 3. Contents of the invention: [0003] The object of the present invention is to provide a new type hydraulic crawler crane, which basically retai...
