May be the cabinet of aluminium alloy used for manufacturing later, people developed the push-pull cabinet.Push-pull cabinet did not stop the problem, because of push-pull cabinet casement opening and closing of stationary state basic same.

The SH130-5 development concept is to achieve:
(1) Easy to operate sports performance (operability + speed + horsepower).
(2) Sensitive quality: Perfect design that perfectly fits the operator's feelings and the customer's voice.
(3) Can adapt to the harsh operating environment reliability. In a nutshell, it is excellent sportiness, excellent comfort and excellent economy. Among them, the sports performance is reflected in: the increase in the amount of work, walking drive force increased by 7.5%, good operability (can automatically increase the digging force); economic performance is mainly reflected in: reduce fuel consumption 15%, the rigidity of structural parts such as small arms to enhance Reliability, standard EMS easy-to-maintain system and other measures make maintenance more convenient; as regards comfort, it mainly includes: wide vision, large cab (1.6 times that of the old model) and low noise.
Both the SH350-5 and SH460HD-5 are further improved on the basis of the original 3B model, and a cooled exhaust gas recirculation (EGR) system is adopted. The Sumitomo patented integrated knob mode is used to greatly improve the operating performance and increase the efficiency. At the same time, it reduces the fuel consumption rate and reflects the organic combination of speed and power of the LEGEST series excavators.
One disadvantage of push-pull cabinet is a must have at least one fixed fan, greatly reduce the cabinet area: the other is a fatal weakness could not meet the requirements of air tightness and water tightness.
Of push-pull cabinet casement fixed point is up and down two guide rail, so the wind pressure strength is limited.Modern building more and more high to the requirement of energy conservation and other functions, the sealing of the cabinet, sound insulation and heat insulation, air tightness and water tightness and wind resistance strength and security level, there are strict requirements.To meet the requirements of a variety of integrated and produced within the batter casement cabinets, or the Europe type cabinet.
The cabinet of modern glass curtain wall building model related to the cabinet frame on the wall of the fixed way.Because the glass curtain wall of air tightness, water tightness and wind resistance strength of the demand is higher, on the curtain wall cabinet accessories, according to the need to develop relatively independent.
Modern architecture of the cabinet is not confined to the level of manpower and starting from the requirements of ventilation heat removal, the height of the cabinet is an important factor decided to take a breath row of thermal efficiency, so people invented all kinds of cabinet.
Following the successful debut of the new SH210-5 and SH240-5 models last year, Sumitomo also launched in August this year three new energy-efficient and efficient excavators, namely the SH130-5, SH350-5 and SH460HD-5.
